Changelog

Sourced from pasts's changelog.

[0.12.0] - 2022-07-31

Added

• no-std feature

Changed

• Executor::new() now takes impl Into<Arc<I>> instead of I
• Executor::spawn() no longer requires Unpin futures
• Sleep trait now requires Send + Sync + 'static
• Started using core::hint::spin_loop() for default no-std executor

Removed

• std feature - to use pasts on no-std environments use the new no-std feature instead

[0.11.0] - 2022-06-10

Added

• Sleep trait for implementing custom executors
• Notifier trait (like AsyncIterator, but infinite)
• Poller struct for compatibility with futures
• Fuse trait for turning Futures into Notifiers
• Executor struct for custom executors
• Loop struct for a notifier created from future producers
• Box, Future, Pin, Exec (alias to core::task::Context), Executor, Fuse, Local, Task and Notifier to prelude.
• Local type alias for !Send boxed Notifiers
• Task type alias for Send boxed Notifiers

Changed

• Loop renamed to Join
• Join::on() now takes a closure for the notifier
• Task got split into many different specialized types

Removed

• poll_next_fn() in favor of new Poller type
• block_on() - all futures must be spawned locally now (this change was made to support the same behavior on web assembly as other platforms)
• BlockOn trait in favor of new Executor struct
• Executor trait in favor of using new Sleep trait in combination with the Wake trait from the std library.

[0.10.0] - 2022-05-07

Added

• More documentation
• poll_next_fn()

Changed

• Completely reimplemented Task so it doesn't always require allocation or Send (it should be more obvious which methods require allocation now)
• Loop::on() accepts different types for the second parameter

... (truncated)

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
