CHANGELOG

This release contains the changes from `polkadot-stable2407-2` to `v1.16.0-rc1`. ## Changelog ### Changelog for `Node Dev` **ℹ️ These changes are relevant to:** Those who build around the client side code. Alternative client builders, SMOLDOT, those who consume RPCs. These are people who are oblivious to the runtime changes. They only care about the meta-protocol, not the protocol itself. #### [#5410]: Reactive syncing metrics Syncing metrics are now updated immediate as changes happen rather than every 1100ms as it was happening before. This resulted in minor, but breaking API changes. #### [#5288]: Added `polkadot-parachain-lib` helper library that can be used to build a parachain node This PR adds the `polkadot-parachain-lib` helper library that can be used to build a parachain node. #### [#4993]: Added BEEFY equivocation-related methods to BeefyApi This PR adds the `generate_ancestry_proof`, `submit_report_fork_voting_unsigned_extrinsic` and `submit_report_future_block_voting_unsigned_extrinsic` to `BeefyApi` and bumps the `BeefyApi` version from 4 to 5. #### [#5393]: Allow to enable full PoV size A feature is introduced allowing a collator to enable full PoV size at compile time. WARNING: To use this feature, security considerations must be understood and the latest SDK version must be used. #### [#5065]: Replace env_logger with sp_tracing This PR replaces env_logger with sp_tracing because of an issue with env_logger and gum #4660 #### [#5344]: Fix storage weight reclaim bug. Improvement in slot worker loop that will not call create inherent data providers if the major sync is in progress. Before it was called every slot and the results were discarded during major sync. #### [#5396]: Simplify `SyncingEngine::new()` Tiny changes to simplify the internal implemenation of API `SyncingEngine::new()` to prevent panics while fetching the genesis hash and to eliminate unnecessary allocation for reserved peers. #### [#4845]: Make approval-distribution logic runnable on a separate thread Pass SubsystemSender trait inside approval-distribution instead of passing SubsystemContext everywhere. This allows us in the future to be able to run multiple approval-distribution instances on different workers. #### [#5364]: Improve `sc-service` API This improves `sc-service` API by not requiring the whole `&Configuration`, using specific configuration options instead. `RpcConfiguration` and `ExecutorConfiguration` were also extracted from `Configuration` to group all RPC and executor options together. If `sc-service` is used as a library with lower-level APIs, `Configuration` can now be avoided in most cases. This mainly impacts you on your node implementation. There you need to change this: ``` with_execution_method(config.wasm_method) ``` to this: ``` with_execution_method(config.executor.wasm_method) ``` There are similar changes required as well, but all are around the initialization of the wasm executor. #### [#4739]: parachain-template - genesis config presets added - common DEV_RUNTIME_PRESET ("development") const added to sp-genesis-builder. - parachain-templates are now using presets. #### [#5195]: Bump Aura authoring duration to 2s. This PR bumps the Aura authoring duration in the asynchronous backing guide and the polkadot-parachain service file to 2s in order to make better use of the provided coretime. #### [#5142]: Move decompression to worker processes Candidate validation subsystem performed the PVF code decompression as well as the PoV decompression itself which might affect the subsystem main loop performance and required it to run on the blocking threadpool. This change moves the decompression to PVF host workers running synchronously in separate processes. #### [#5431]: Remove the need to wait for target block header in warp sync implementation Previously warp sync needed to wait for target block header of the relay chain to become available before warp sync can start, which resulted in cumbersome APIs. Parachain initialization was refactored to initialize warp sync with target block header from the very beginning, improving and simplifying sync API. #### [#5527]: Report BestBlock events only for newBlock reports This PR ensures that the chainHead_v1_follow method of the RPC-v2 API is always reporting a `BestBlock` event after a `NewBlock`. There was a race condition in the chainHead follow logic which led to the `BestBlock` event to be emitted without an associated `NewBlock` event. #### [#4928]: Move assignment VRF check and vote signature in approval-distribution This PR moves the assignment VRF check and approval vote signature from approval-voting into approval-distribution. This optimization creates a better pipelining for processing new messages, because in this way approval-distribution does not have to wait after approval-voting anymore and it will just notify it when it received a valid message that is ready to be imported. #### [#5450]: Sync status refactoring `SyncingService` API in `sc-network-sync` has changed with some of the redundant methods related to sync status removed that were mostly used internally or for testing purposes and is unlikely to impact external code. `ExtendedPeerInfo` now has working `Clone` and `Copy` implementation. #### [#5424]: Suppress the log output for transaction propagation when no transactions are present Previously, the log message `Propagating transactions` would always be printed, even when there were no transactions to propagate. This patch optimizes the logging by returning early when no transactions are present, resulting in cleaner and more relevant log output. #### [#5250]: Export `MetricsService` and add public constructor to `RpcHandlers` `sc-service` was missing just a couple of things in public API in order to make it possible to recreate its `spawn_tasks`, specifically `MetricsService` struct and `RpcHandlers` didn't have public constructor, which were both finally addressed. #### [#5029]: Backoff slow peers to avoid duplicate requests This PR introduces a backoff strategy mechanism. Whenever a peer disconnects with an inflight block (or state) request, the peer is backed off for a period of time before receiving requests. After several attempts, the peer is disconnected and banned. The strategy aims to offload the pressure from peers that are slow to respond or overloaded. #### [#5339]: Replace unnecessary `&mut self` with `&self` in `BlockImport::import_block()` Simplifies block import API to match intended design where independent blocks can technically be imported concurrently and in practice was called through `Arc` anyway #### [#5352]: Aura: Ensure parachains are building on all relay chain forks Ensure that parachains using the `basic` collator are building on all relay chain forks. #### [#5269]: Added the possibility to build a parachain node with block number u64 Added the possibility to build a parachain node with block number u64. #### [#3786]: Make changing of peer-id while active a bit more robust Implemetation of https://github.com/polkadot-fellows/RFCs/pull/91, to use `creation_time` field to determine the newest DHT record and to update nodes known to have the old record. Gossip-support is modified to try to re-resolve new address authorithies every 5 minutes instead of each session, so that we pick autorithies that changed their address faster and try to connect to them. #### [#5252]: Additional logging in `dispute-coordinator` subsystem Additional logging in `dispute-coordinator` subsystem tracing the list of offchain disabled validators and the reason why an import statement is considered spam. #### [#5316]: add timestamp function to sp-consensus-slots Added timestamp function to sp-consensus-slots to get the first timestamp of the given slot. #### [#3996]: asset-hub-rococo - genesis config presets added `asset-hub-rococo` genesis state was moved to runtime. #### [#5356]: Fix OurViewChange small race Always queue OurViewChange event before we send view changes to our peers, because otherwise we risk the peers sending us a message that can be processed by our subsystems before OurViewChange. Normally, this is not really a problem because the latency of the ViewChange we send to our peers is way higher than that of our subsystem processing OurViewChange, however on testnets like versi where CPUs are sometimes overcommitted this race gets triggered occasionally, so let's fix it by sending the messages in the right order. #### [#2923]: Use `console` crate instead of `ansi_term` This PR replace obsoleted `ansi_term` to `console`. #### [#5538]: collator-protocol: Remove race condition Remove a race condition in the collator protocol that could lead to collations not being announced to a validator. ### Changelog for `Runtime Dev` **ℹ️ These changes are relevant to:** All of those who rely on the runtime. A parachain team that is using a pallet. A DApp that is using a pallet. These are people who care about the protocol (WASM, not the meta-protocol (client).) #### [#4963]: Removed `pallet::getter` usage from the pallet-proxy This PR removed `pallet::getter`s from `pallet-proxy`s storage items. When accessed inside the pallet, use the syntax `StorageItem::::get()`. #### [#5132]: Add `from_mel` for `Footprint` This introduces a new way to generate the `Footprint` type by calculating the max encoded length of some generic type. This allows you to generate a `Footprint` of a type without actually constructing that type. #### [#5262]: Correct some typos in crates' descriptions Corrected typos and copy-paste errors in crates' descriptions. #### [#4962]: Removed `pallet::getter` usage from the pallet-treasury This PR removed `pallet::getter`s from `pallet-treasury`s storage items. Instead use the syntax `StorageItem::::get()`. #### [#5513]: Add more logs to trace AcceptanceCheckErr `Debug` was derived on `AcceptanceCheckErr` to print the error. This PR adds more logs to trace the error. #### [#4706]: Rename `assigner_on_demand` pallet to `on_demand` Renames `assigner_on_demand` pallet to `on_demand` #### [#5114]: Remove not-audited warning Pallets `tx-pause` and `safe-mode` have passed audit, this just removes a warning in the docs to not use them. #### [#5173]: Umbrella crate: exclude chain-specific crates The `polkadot-sdk` umbrella crate does now not contain chain-specific crates. The reasoning is that the SDK should be mostly chain-agnostic. Please check out [psvm](https://github.com/paritytech/psvm) to select matching version numbers for chain- specific crates. #### [#5078]: Add possibility to inject non-authorities session-keys in genesis Allows to inject a set of registered session-keys in pallet-session that are not part of the first initial set of validators #### [#4527]: Call implementation for `transfer_all` This PR introduces the `transfer_all` call for `pallet-assets`. The parameters are analog to the same call in `pallet-balances`. This change is expected to be backwards-compatible. This change requires running benchmarkings to set accurate weights for the call. #### [#4487]: Remove `pallet::getter` usage from pallet-election-provider-multi-phase This PR removes the `pallet::getter`s from `pallet-election-provider-multi-phase`. The syntax `StorageItem::::get()` should be used instead. #### [#5369]: Fix failing XCM from relay to Coretime Chain when revenue is zero The coretime assigner now always includes UnpaidExecution when calling `notify_revenue` via a `Transact`, not just when revenue is nonzero. This fixes an issue where the XCM would fail to process on the receiving side. #### [#4998]: Ensure members can always exit the pool gracefully Ensures when a member wants to withdraw all funds but the pool is not able to provide all their funds, the member can receive as much as possible and exit pool. Also handles cases where some extra funds held in member's account is released when they are removed. #### [#5467]: Make PendingConfigs storage item public Make PendingConfigs storage item in polkadot's configuration crate public. #### [#4956]: Add build options to the srtool build step and delete `disanle-logging` feature This PR adds possibility to set BUILD_OPTIONS to the "Srtool Build\" step in the release pipeline while building runtimes. And deletes the `disable-logging` feature from test runtimes to be able to build those with an activated logging. #### [#4564]: Make `OnUnbalanced::on_unbalanceds` work with `fungibles` `imbalances` The `on_unbalanceds` function of `OnUnbalanced` trait accepts the `fungibles` `imbalances` imbalances. This is done by replacing the `Imbalance` trait bound on imbalance type with the `TryMerge` trait bound. The `TryMerge` trait is implemented for all imbalance types. ### Migration for `OnUnbalanced` trait implementations: In case if you have a custom implementation of `on_unbalanceds` trait function, remove it's `` type argument. ### Migration for custom imbalance types: If you have your own imbalance types implementations, implement the `TryMerge` trait for it introduced with this update. #### [#5201]: Snowbridge free consensus updates Allow free consensus updates to the Snowbridge Ethereum client if the headers are more than a certain number of headers apart. Relayers providing valid consensus updates are refunded for updates. Bridge users are not affected. #### [#4976]: Add pub to xcm::v4::PalletInfo Forgot to make v4 PalletInfo fields public. Without them we cannot make use of the struct. #### [#5074]: Snowbridge on Westend Since Rococo is now deprecated, we need another testnet to detect bleeding-edge changes to Substrate, Polkadot, BEEFY consensus protocols that could brick the bridge. #### [#5074]: Snowbridge on Westend Like Rococo this PR enables the fast-runtime feature by default which is easier for testing beefy stuff on westend-local. #### [#5055]: Only log error in `UnixTime::now` call of the pallet-timestamp implementation if called at genesis This minor patch re-introduces a check to ensure that the `UnixTime::now` implementation in the timestamp only logs an error if called at the genesis block. #### [#5131]: Swap for paying delivery fees in different assets Using the `AssetExchanger` XCM config item, the executor now swaps fees to use for delivery fees, if possible. If you want your runtime to support this, you need to configure this new item. Thankfully, `xcm-builder` now has a new adapter for this, which lets you use `pallet-asset-conversion` or any type that implements the `SwapCredit` and `QuotePrice` traits. It's called `SingleAssetExchangeAdapter`, you can read more about it in its rust docs. This item is already configured in Asset Hub. IMPORTANT: The executor now only takes the first asset for delivery fees. If you have configured a custom router that returns more than one asset for delivery fees, then only the first one will be taken into account. This is most likely not what you want. #### [#5130]: Add SingleAssetExchangeAdapter SingleAssetExchangeAdapter is an adapter in xcm-builder that can be used to configure the AssetExchanger in XCM to use pallet-asset-conversion, or any other type that implements the `SwapCredit` and `QuotePrice` traits. It can be configured as follows: ```rust pub type AssetExchanger = SingleAssetExchangeAdapter< // pallet-assets-conversion, as named in `construct_runtime`. AssetConversion, // The fungibles implementation that brings together all assets in pools. // This may be created using `fungible::UnionOf` to mix the native token // with more tokens. Fungibles, // The matcher for making sure which assets should be handled by this exchanger. Matcher, >; ``` It's called "single asset" since it will only allow exchanging one asset for another. It will error out if more than one asset tries to be exchanged. Also, a new method was added to the `xcm_executor::traits::AssetExchange` trait: `quote_exchange_price`. This is used to get the exchange price between two asset collections. If you were using the trait, you now need to also implement this new function. #### [#4936]: Balances Pallet: Emit events when TI is updated in currency impl Previously, in the Currency impl, the implementation of pallet_balances was not emitting any instances of Issued and Rescinded events, even though the Fungible equivalent was. This PR adds the Issued and Rescinded events in appropriate places in impl_currency along with tests. #### [#5442]: Derive `Clone` on `EncodableOpaqueLeaf` `Clone` was derived on `EncodableOpaqueLeaf` for convenience of downstream users #### [#5354]: Fix benchmark failures when using insecure_zero_ed flag Currently, when the pallet is compiled with the insecure_zero_ed flag, benchmarks fail because the minimum balance is set to zero. The PR aims to resolve this issue by implementing a placeholder value for the minimum balance when the insecure_zero_ed flag is active. it ensures that benchmarks run successfully regardless of whether this flag is used or not #### [#4822]: Ensure as many as possible pool members can migrate to `DelegateStake` 1. Allows pool members to use their total balance while joining pool with `DelegateStake`. 2. Gates call mutating pool or member in unmigrated state. 3. Runtime apis for reading pool and member balance. #### [#5204]: Pallet assets: fix doc: start_destroy never required asset to be frozen In pallet assets calling `start_destroy` doesn't require the asset to be frozen. Doc is fixed. #### [#5465]: try-state check invariant for nomination-pools (points >= stake) Adds a new try-state invariant to the nomination pools that checks that for each bonded pool, the pool's points can never be lower than its staked balance. #### [#4460]: xcm-executor: allow deposit of multiple assets if at least one of them satisfies ED XCM programs that deposit assets to some new (empty) account will now succeed if at least one of the deposited assets satisfies ED. Before this change, the requirement was that the _first_ asset had to satisfy ED, but assets order can be changed during reanchoring so it is not reliable. Now, ordering doesn't matter, any one(s) of them can satisfy ED for the whole deposit to work. #### [#5443]: change try-runtime rpc domains as part of https://github.com/paritytech/devops/issues/3502, try-runtime nodes were migrated to a new provider with a new domain address. The PR fixes all the references to try-runtime nodes on rococo, westend, kusama and polkadot networks #### [#5430]: pallet-collator-selection: correctly register weight in `new_session` - Fixes an incorrect usage of the `WeightInfo` trait for `new_session`. #### [#5604]: Clear other messages before dry-running The DryRunApi.dry_run_call and DryRunApi.dry_run_xcm functions used to populate `forwarded_xcms` with all the existing messages in the queues at the time. Now, existing (irrelevant) messages are cleared when dry-running, meaning only the messages produced by the dry-run call (or xcm) will be returned in `forwarded_xcms`. #### [#5257]: Enable proof-recording in benchmarking We now enable proof recording in the timing benchmarks. This affects the standalone `frame-omni-bencher` as well as the integrated benchmarking commands of the node. For parachains on recent versions of polkadot-sdk this is the correct default setting, since PoV-reclaim requires proof recording to be enabled on block import. This comes with a slight increase in timing weight due to the additional overhead. Relay- or solo-chains which do not need proof recording can restore the old behaviour by passing `--disable-proof-recording` to the benchmarking command. In addition, the `ProofSizeExt` extension is available during benchmarking. #### [#5293]: Add initial version of pallet_revive Adds initial **experimental** version of the new pallet_revive. It will run PolkaVM contracts which were recompiled from YUL using the revive compiler. Do not use the pallet in production, yet. It is work in progress. #### [#5174]: Wasm-builder: Set the `resolver` version to `2` Set the `resolver` version to `2` in the generated `Cargo.toml`. #### [#4751]: Use all parachain heads for BEEFY MMR extra data Previously, the extra data in an MMR leaf nodes was only computed based on lease-based parachain heads. This PR extends the extra data to include others, including on-demand parachain heads. Currently, the number of heads is limited to the first 1024 heads sorted by para id. #### [#4999]: Fixes entropy for derivation of proxy delegator account. This fixes how ProxyDelegator accounts are derived but may cause issues in Westend since it would use the old derivative accounts. Does not affect Polkadot/Kusama as this pallet is not deployed to them yet. #### [#4959]: relax XcmFeeToAccount trait bound on AccountId This PR relaxes the trait bound on AccountId for the XcmFeeToAccount struct by introducing a new struct called `SendXcmFeeToAccount`. The old one (`XcmFeeToAccount`) will be deprecated at January 2025. #### [#4930]: Add test macro to emulated chains This PR adds a portable test macro that can be used to test trapped assets can be claimed in an emulated chain. #### [#4586]: Removed `pallet::getter` usage from pallet-identity This PR removed the `pallet::getter`s from `pallet-identity`. The syntax `StorageItem::::get()` should be used instead. #### [#4970]: Remove `pallet::getter` usage from the transaction-payment pallet This PR removes the `pallet::getter`s from `pallet-transaction-payment`. The syntax `StorageItem::::get()` should be used instead. #### [#5380]: Fix leases with gaps and time slice calculation in MigrateToCoretime Agile Coretime storage migration wasn't transferring correctly leases with gaps and was miscalculating time lease period. This patch provides fixes for both issues. #### [#5348]: allow for u8 to be used as hold/freeze reason Allows for `u8` type to be configured as `HoldReason` and `FreezeReason` #### [#5155]: Use umbrella crate for minimal template Minor additions to the `polkadot-sdk-frame` crate and making it ready for usage in more templates. This PR already integrates it in the minimal template. #### [#5113]: Make the candidate relay parent progression check more strict for elastic scaling Previously, the relay chain runtime was checking if the relay parent of a new candidate does not move backwards from the latest included on-chain candidate. This was fine prior to elastic scaling. We now need to also check that the relay parent progresses from the latest pending availability candidate, as well as check the progression within the candidate chain in the inherent data. Prospective-parachains is already doing this check but it's also needed in the runtime. #### [#4967]: Remove `pallet::getter` usage from the balances pallet This PR removes the `pallet::getter`s from `pallet-balances`. The syntax `StorageItem::::get()` should be used instead. #### [#5082]: Fix ParaInherent weight overestimation This PR fixes the relay chain inherent weight overestimation allowing it to support more cores and validators. #### [#3996]: asset-hub-rococo - genesis config presets added `asset-hub-rococo` genesis state was moved to runtime. #### [#4949]: [bridges-v2] Permissionless lanes This PR adds support for opening and closing dynamic, also known as permissionless, lanes. This means that authorized origins (relay chain, sibling parachains) can open and close bridges with other bridged (substrate-like) consensuses supported by Bridge Hubs. The Bridge Hubs, particularly the `pallet-xcm-bridge-hub`, introduce new extrinsics `open_bridge` and `close_bridge`, which can be called using `xcm::Transact`. #### [#4488]: Tx Payment: drop ED requirements for tx payments with exchangeable asset Drop the Existential Deposit requirement for the asset amount exchangeable for the fee asset (eg. DOT/KSM) during transaction payments. This achieved by using `SwapCredit` implementation of asset conversion, which works with imbalances and does not require a temporary balance account within the transaction payment. This is a breaking change for the `pallet-asset-conversion-tx-payment` pallet, use examples from PR for the migration. #### [#5270]: Inclusion: account for enact_candidate weight We are now properly accounting for the `enact_candidate`s weight in processing of a relay chain block inherent. This may result in some of the user relay chain transactions not being included in the block if it's really heavy. This should be fine though as we are moving towards the minimal relay chain. #### [#5384]: `MaybeConsideration` extension trait for `Consideration` The trait allows for the management of tickets that may represent no cost. While the `MaybeConsideration` still requires proper handling, it introduces the ability to determine if a ticket represents no cost and can be safely forgotten without any side effects. The new trait is particularly useful when a consumer expects the cost to be zero under certain conditions (e.g., when the proposal count is below a threshold N) and does not want to store such consideration tickets in storage. The extension approach allows us to avoid breaking changes to the existing trait and to continue using it as a non-optional version for migrating pallets that utilize the `Currency` and `fungible` traits for `holds` and `freezes`, without requiring any storage migration. #### [#5359]: Make ticket non-optional and add ensure_successful method to Consideration trait Make ticket non-optional and add ensure_successful method to Consideration trait. Reverts the optional return ticket type for the new function introduced in [polkadot-sdk/4596](https://github.com/paritytech/polkadot-sdk/pull/4596) and adds a helper `ensure_successful` function for the runtime benchmarks. Since the existing FRAME pallet represents zero cost with a zero balance type rather than `None` in an option, maintaining the ticket type as a non-optional balance is beneficial for backward compatibility and helps avoid unnecessary migrations. #### [#5466]: frame-omni-bencher maintenance Changes: - Set default level to `Info` again. Seems like a dependency update set it to something higher. - Fix docs to not use `--locked` since we rely on dependency bumps via cargo. - Add README with rust docs. - Fix bug where the node ignored `--heap-pages` argument. ### Changelog for `Node Operator` **ℹ️ These changes are relevant to:** Those who don't write any code and only run code. #### [#5129]: Prevent finalized notification hoarding in beefy gadget This PR fixes the error message "Notification block pinning limit reached." during warp sync. Finality notifications in BEEFY are now constantly being consumed and don't keep blocks pinned for extended periods of time. #### [#5326]: Update Readme of the `polkadot` crate Updated Readme of the `polkadot` crate. #### [#5436]: Add Polkadot Coretime Chain genesis chain-spec The Polkadot Coretime Chain can now be run as all other system parachains without specifying a chain-spec. However this will soon be deprecated and `--chain ./chain-spec.json` should continue to be used instead. #### [#5240]: Warn on empty public-addr when starting a validator node This PR shows a warning when the `--public-addr` CLI parameter is missing for validators. In the future, we'll transform this warning into a hard failure. Validators are encouraged to provide this parameter for better availability over the network. #### [#5197]: Prevent `ConsensusReset` by tolerating runtime API errors in BEEFY After warp sync, the BEEFY worker was trying to execute runtime calls on blocks which had their state already pruned. This led to an error and restarting of the beefy subsystem in a loop. After this PR, the worker tolerates call errors and therefore prevents this worker restart loop. #### [#4792]: rpc: bind to `ipv6` if available and add `CLI --experimental-rpc-endpoint` to specify listen addr This PR changes/adds the following: 1. The default setting is that substrate starts a rpc server that listens to localhost both ipv4 and ipv6 on the same port. ipv6 is allowed to fail because some platforms may not support it 2. A new RPC CLI option `--experimental-rpc-endpoint` is introduced which allows to configure arbitrary listen addresses including the port, if this is enabled no other interfaces are enabled. 3. If the local addr is not found for any of the sockets the server is not started and throws an error. 4. Remove the deny_unsafe from the RPC implementations instead this is an extension to allow different polices for different interfaces/sockets such one may enable unsafe on local interface and safe on only the external interface. 5. This new `--experimental-rpc-endpoint` has several options and in the help menu all possible parameters are documented. 6. The log emitted by jsonrpc server when it has been started has been modified to indicate all started rpc endpoints. So for instance it's now possible to start up three RPC endpoints as follows: ``` $ polkadot --experimental-rpc-endpoint "listen-addr=127.0.0.1:9944,methods=unsafe" --experimental-rpc-endpoint "listen-addr=0.0.0.0:9945,methods=safe,rate-limit=100" --experimental-rpc-endpoint "listen-addr=[::1]:9944,optional=true" ``` #### [#5196]: Bring benchmark inline with reference machine used for weights - BLAKE2-256 reference values were too low(~30%) when compared with the machine used for generating the weights, so it was brought in sync with results on the reference hardware recommended here: https://wiki.polkadot.network/docs/maintain-guides-how-to-validate-polkadot#reference-hardware - SR25519-Verify reference values were too low(~10%) when compared with the machine used for generating the weights, so it was brought in sync with results on the reference hardware recommended here: https://wiki.polkadot.network/docs/maintain-guides-how-to-validate-polkadot#reference-hardware - Validators where the `BLAKE2-256` and `SR25519-Verify` were barely passing, might received the warning that they are not compliant anymore, this should not be treated as critical, but they should take the necessary steps to become compliant in the near/mid-term future. - Note!: The reference hardware requirements have not been increased we just fixed the benchmark which was wrongly reporting lower spec HW as being compliant. #### [#5124]: Add Polkadot Chain genesis chainspec The Polkadot People Chain can now be run as all other system parachains without specifying a chainspec. However this will soon be deprecated and `--chain ./chainspec.json` should continue to be used instead. #### [#5214]: make polkadot-parachain startup errors pretty Changed the format of how polkadot-parachain prints the startup errors to include the full displayable context. #### [#5392]: Don't disconnect disabled nodes sending us dispute messages No longer disconnect peers which we consider disabled when raising disputes as this will affect the approval process and thus finality. ### Changelog for `Runtime User` **ℹ️ These changes are relevant to:** Anyone using the runtime. This can be a token holder or a dev writing a front end for a chain. #### [#5036]: [pallet_contracts] Modify the storage host function benchmarks to be run on an unbalanced storage trie This PR modifies the storage host function benchmarks. Previously, they were run on an empty storage trie. Now, they are run on an unbalanced storage trie to reflect the worst-case scenario. This approach increases the storage host function weights and decreases the probability of DoS attacks. #### [#4424]: Coretime auto renewal With the additions in this PR, any task that utilizes a core that can be auto-renewed can enable auto-renewal. The renewal is paid from the task's sovereign account. The two new extrinsics for controlling auto-renewal are `enable_auto_renew` and `disable_auto_renew`. #### [#4613]: pallet-conviction-voting: Include events for vote and remove vote Introduce event called `Voted: { who: T::AccountId, vote: AccountVote> }` and `VoteRemoved: { who: T::AccountId, vote: AccountVote> }` #### [#5436]: Add Polkadot Coretime Chain genesis chain-spec The Polkadot Coretime Chain chain-specs have been added to the polkadot-sdk repo and can now be pulled from there along with all other system chains. #### [#4938]: introduce pallet-parameters to Westend to parameterize inflation This PR adds `pallet-parameters` to the Westend runtime, and makes the inflation formula be adjustable based on this. Moreover, the old `era_payout` function has been removed from `polkadot_runtime_common` and is replaced by `relay_era_payout`. This function is only meant to be used in the Polkadot relay chains, and other users are encouraged to provide their own implementation of `type EraPayout`. #### [#5131]: Swap for paying delivery fees in different assets If the `AssetExchanger` is configured on a runtime, the XCM executor is now able to swap assets to pay for delivery fees. This was already possible for execution fees via the `SwapFirstAssetTrader`. A runtime where this will be possible is Asset Hub. That means reserve asset transfers from Parachain A to Parachain B passing through Asset Hub no longer need to have any DOT to pay for fees on AssetHub. They can have any asset in a pool with DOT on Asset Hub, for example USDT or USDC. #### [#4460]: xcm-executor: allow deposit of multiple assets if at least one of them satisfies ED XCM programs that deposit assets to some new (empty) account will now succeed if at least one of the deposited assets satisfies ED. Before this change, the requirement was that the _first_ asset had to satisfy ED, but assets order can be changed during reanchoring so it is not reliable. Now, ordering doesn't matter, any one(s) of them can satisfy ED for the whole deposit to work. #### [#4973]: [pallet_contracts] Increase the weight of the deposit_event host function to limit the memory used by events. This PR updates the weight of the deposit_event host function by adding a fixed ref_time of 60,000 picoseconds per byte. Given a block time of 2 seconds and this specified ref_time, the total allocation size is 32MB. #### [#5124]: Add Polkadot Chain genesis chainspec The Polkadot People Chain chainspecs have been added to the polkadot-sdk repo and can now be pulled from there along with all other system chains. #### [#5067]: Fix region nonfungible implementation PR fixes the issue with the current implementation where minting causes the region coremask to be set to `Coremask::complete` regardless of the actual coremask of the region. ## Rust compiler versions This release was built and tested against the following versions of `rustc`.
