Release Notes

dafny-lang/dafny (org.dafny:DafnyRuntime)

### [`v4.8.0`](https://togithub.com/dafny-lang/dafny/blob/HEAD/RELEASE_NOTES.md#480) #### New features - Introduce `hide` statements that enable hiding the body of a function at a particular proof location, which allows simplifying the verification of that proof in case the body of the function is not needed for the proof. `Hide` statements make the opaque keyword on functions obsolete. ([https://github.com/dafny-lang/dafny/pull/5562](https://togithub.com/dafny-lang/dafny/pull/5562)) - Let the command `measure-complexity` output which verification tasks performed the worst in terms of resource count. Output looks like: ... Verification task on line 8 in file measure-complexity.dfy consumed 9984 resources Verification task on line 7 in file measure-complexity.dfy consumed 9065 res[https://github.com/dafny-lang/dafny/pull/5631](https://togithub.com/dafny-lang/dafny/pull/5631)lang/dafny/pull/5631) - Enable the option `--enforce-determinism` for the commands `resolve` and `verify` ([https://github.com/dafny-lang/dafny/pull/5632](https://togithub.com/dafny-lang/dafny/pull/5632)) - Method calls get an optional by-proof that hides the precondtion and its proof ([https://github.com/dafny-lang/dafny/pull/5662](https://togithub.com/dafny-lang/dafny/pull/5662)) #### Bug fixes - Clarify error location of inlined `is` predicates. ([https://github.com/dafny-lang/dafny/pull/5587](https://togithub.com/dafny-lang/dafny/pull/5587)) - Optimize the compilation of single-LHS assignment statements to allow the RHS to be a deeply nested expression. This solves a problem in compiling to Java, since `javac` does not deal gracefully with nested lambda expressions. ([https://github.com/dafny-lang/dafny/pull/5589](https://togithub.com/dafny-lang/dafny/pull/5589)) - Crash when compiling an empty source file while including testing code ([https://github.com/dafny-lang/dafny/pull/5638](https://togithub.com/dafny-lang/dafny/pull/5638)) - Let the options --print-mode=NoGhostOrIncludes and --print-mode=NoIncludes work ([https://github.com/dafny-lang/dafny/pull/5645](https://togithub.com/dafny-lang/dafny/pull/5645)) - Verification in the IDE now works correctly when declaring nested module in a different file than their parent. ([https://github.com/dafny-lang/dafny/pull/5650](https://togithub.com/dafny-lang/dafny/pull/5650)) - Fix NRE that would occur when using --legacy-data-constructors ([https://github.com/dafny-lang/dafny/pull/5655](https://togithub.com/dafny-lang/dafny/pull/5655)) ### [`v4.7.0`](https://togithub.com/dafny-lang/dafny/blob/HEAD/RELEASE_NOTES.md#470) #### New features - Add the option --find-project that given a Dafny file traverses up the file tree until it finds a Dafny project that includes that path. This is useful when developing a particular file and doing CLI invocations as part of your development workflow. - Improved error reporting when verification times out or runs out of resources, so that when using `--isolate-assertions`, the error message points to the problematic assertion. ([https://github.com/dafny-lang/dafny/pull/5281](https://togithub.com/dafny-lang/dafny/pull/5281)) - Support newtypes based on map and imap ([https://github.com/dafny-lang/dafny/pull/5175](https://togithub.com/dafny-lang/dafny/pull/5175)) - To enable smoothly working with multiple projects inside a single repository, Dafny now allows using a Dafny project file as an argument to `--library`. When using `dafny verify`, Dafny ensures that any dependencies specified through a project are verified as well, unless using the flag `--dont-verify-dependencies`. ([https://github.com/dafny-lang/dafny/pull/5297](https://togithub.com/dafny-lang/dafny/pull/5297)) - Experimental Dafny-to-Rust compiler development - Supports emitting code even if malformed with option `--emit-uncompilable-code`. - Supports for immutable collections and operators [https://github.com/dafny-lang/dafny/pull/5081](https://togithub.com/dafny-lang/dafny/pull/5081)ull/5081) - Allow for plugins to add custom request handlers to the language server. ([https://github.com/dafny-lang/dafny/pull/5161](https://togithub.com/dafny-lang/dafny/pull/5161)) - Deprecated the unicode-char option ([https://github.com/dafny-lang/dafny/pull/5302](https://togithub.com/dafny-lang/dafny/pull/5302)) - Warn when passing a Dafny source file to `--library` ([https://github.com/dafny-lang/dafny/pull/5313](https://togithub.com/dafny-lang/dafny/pull/5313)) - Add support for "translation records", which record the options used when translating library code. - `--translation-record` - Provides a `.dtr` file from a previous translation of library code. Can be specified multiple times. - `--translation-record-output` - Customizes where to write the translation record for the current translation. Defaults to the output directory. Providing translation records is necessary to handle options such as `--outer-module` that affect how code is translated. [https://github.com/dafny-lang/dafny/pull/5346](https://togithub.com/dafny-lang/dafny/pull/5346)ull/5346) - The new `decreases to` expression makes it possible to write an explicit assertion equivalent to the internal check Dafny does to prove that a loop or recursive call terminates. ([https://github.com/dafny-lang/dafny/pull/5367](https://togithub.com/dafny-lang/dafny/pull/5367)) - The new `assigned` expression makes it possible to explicitly assert that a variable, constant, out-parameter, or object field is definitely assigned. ([https://github.com/dafny-lang/dafny/pull/5501](https://togithub.com/dafny-lang/dafny/pull/5501)) - Greatly reduced the size of generated code for the backends: C#, Python, GoLang and JavaScript. - Introduce additional warnings that previously only appeared when running the `dafny audit` command. Two warnings are as follows: - Emit a warning when exporting a declaration that has requires clauses or subset type inputs - Emit a warning when importing a declaration that has ensures clauses or subset type outputs Those two can be silenced with the flag `--allow-external-contracts`. A third new warning occurs when using bodyless functions marked with `{:extern}`, and can be silenced using the option `--allow-external-function`. - Enable project files to specify another project file as a base, which copies all configuration from that base file. More information can be found in the reference manual. #### Bug fixes - Fix a common memory leak that occurred when doing verification in the IDE that could easily consume gigabytes of memory. - Fix bugs that could cause the IDE to become unresponsive - Improve the performance of the Dafny IDE by fixing bugs in its caching code - No longer reuse SMT solver processes between different document version when using the IDE, making the IDE verification behavior more inline to that of the CLI - Fix bugs that caused Dafny IDE internal errors ([https://github.com/dafny-lang/dafny/issues/5355](https://togithub.com/dafny-lang/dafny/issues/5355), [https://github.com/dafny-lang/dafny/pull/5543](https://togithub.com/dafny-lang/dafny/pull/5543), [https://github.com/dafny-lang/dafny/pull/5548](https://togithub.com/dafny-lang/dafny/pull/5548)) - Fix bugs in the Dafny IDEs code navigation and renaming features when working with definition that are not referred to. - Fix a code navigation bug that could occur when navigating to and from module imports - - Fix a code navigation bug that could occur when navigating to and from explicit types of variables [https://github.com/dafny-lang/dafny/pull/5419](https://togithub.com/dafny-lang/dafny/pull/5419)5419) - Let the IDE no longer show diagnostics for projects for which all files have been closed ([https://github.com/dafny-lang/dafny/pull/5437](https://togithub.com/dafny-lang/dafny/pull/5437)) - Fix bug that could lead to an unresponsive IDE when working with project files ([https://github.com/dafny-lang/dafny/pull/5444](https://togithub.com/dafny-lang/dafny/pull/5444)) - Fix bugs in Dafny library files that could cause them not to work with certain option values, such as --function-syntax=3 - Fix a bug that prevented building Dafny libraries for Dafny projects that could verify without errors. - Reserved module identifiers correctly escaped in GoLang ([https://github.com/dafny-lang/dafny/pull/4181](https://togithub.com/dafny-lang/dafny/pull/4181)) - Fix a soundness issue that could be triggered by calling ensures fresh in the post-condition of a constructor ([https://github.com/dafny-lang/dafny/pull/4700](https://togithub.com/dafny-lang/dafny/pull/4700)) - Ability to cast a datatype to its trait when overriding functions ([https://github.com/dafny-lang/dafny/pull/4823](https://togithub.com/dafny-lang/dafny/pull/4823)) - Fix crash that could occur when using a constructor in a match pattern where a tuple was expected ([https://github.com/dafny-lang/dafny/pull/4860](https://togithub.com/dafny-lang/dafny/pull/4860)) - No longer emit an incorrect internal error while waiting for verification message ([https://github.com/dafny-lang/dafny/pull/5209](https://togithub.com/dafny-lang/dafny/pull/5209)) - More helpful error messages when read fields not mentioned in reads clauses ([https://github.com/dafny-lang/dafny/pull/5262](https://togithub.com/dafny-lang/dafny/pull/5262)) - Check datatype constructors for bad type-parameter instantiations ([https://github.com/dafny-lang/dafny/pull/5278](https://togithub.com/dafny-lang/dafny/pull/5278)) - Avoid name clashes with Go built-in modules ([https://github.com/dafny-lang/dafny/pull/5283](https://togithub.com/dafny-lang/dafny/pull/5283)) - Invalid Python code for nested set and map comprehensions ([https://github.com/dafny-lang/dafny/pull/5287](https://togithub.com/dafny-lang/dafny/pull/5287)) - Stop incorrectly emitting the error message "Dafny encountered an internal error while waiting for this symbol to verify" ([https://github.com/dafny-lang/dafny/pull/5295](https://togithub.com/dafny-lang/dafny/pull/5295)) - Rename the `dafny generate-tests` option `--coverage-report` to `--expected-coverage-report` ([https://github.com/dafny-lang/dafny/pull/5301](https://togithub.com/dafny-lang/dafny/pull/5301)) - Stop giving an incorrect warning about a missing {:axiom} clause on an opaque constant. ([https://github.com/dafny-lang/dafny/pull/5306](https://togithub.com/dafny-lang/dafny/pull/5306)) - No new resolver crash when datatype update expressions are partially resolved ([https://github.com/dafny-lang/dafny/pull/5331](https://togithub.com/dafny-lang/dafny/pull/5331)) - Optional pre-type won't cause a crash anymore ([https://github.com/dafny-lang/dafny/pull/5369](https://togithub.com/dafny-lang/dafny/pull/5369)) - Unguarded enumeration of bound variables in set and map comprehensions ([https://github.com/dafny-lang/dafny/pull/5402](https://togithub.com/dafny-lang/dafny/pull/5402)) - Reference the correct `this` after removing the tail call of a function or method ([https://github.com/dafny-lang/dafny/pull/5474](https://togithub.com/dafny-lang/dafny/pull/5474)) - Apply name mangling to datatype names in Python more often ([https://github.com/dafny-lang/dafny/pull/5476](https://togithub.com/dafny-lang/dafny/pull/5476)) - Only guard `this` when eliminating tail calls, if possible ([https://github.com/dafny-lang/dafny/pull/5524](https://togithub.com/dafny-lang/dafny/pull/5524)) - Compiled disjunctive nested pattern matching no longer crashing ([https://github.com/dafny-lang/dafny/pull/5572](https://togithub.com/dafny-lang/dafny/pull/5572)) ### [`v4.6.0`](https://togithub.com/dafny-lang/dafny/blob/HEAD/RELEASE_NOTES.md#460) #### New features - Add a check to `dafny run` that notifies the user when a value that was parsed as a user program argument, and which occurs before a `--` token, starts with `--`, since this indicates they probably mistyped a Dafny option name. ([https://github.com/dafny-lang/dafny/pull/5097](https://togithub.com/dafny-lang/dafny/pull/5097)) - Add an option --progress that can be used to track the progress of verification. ([https://github.com/dafny-lang/dafny/pull/5150](https://togithub.com/dafny-lang/dafny/pull/5150)) - Add the attribute `{:isolate_assertions}`, which does the same as `{:vcs_split_on_every_assert}`. Deprecated `{:vcs_split_on_every_assert}` ([https://github.com/dafny-lang/dafny/pull/5247](https://togithub.com/dafny-lang/dafny/pull/5247)) #### Bug fixes - (soundness issue) Twostate predicate now check if their not new arguments are allocated in the previous heap ([https://github.com/dafny-lang/dafny/pull/4844](https://togithub.com/dafny-lang/dafny/pull/4844)) - Add uniform checking of type characteristics in refinement modules ([https://github.com/dafny-lang/dafny/pull/5146](https://togithub.com/dafny-lang/dafny/pull/5146)) - Fixed links associated with the standard libraries. ([https://github.com/dafny-lang/dafny/pull/5176](https://togithub.com/dafny-lang/dafny/pull/5176)) - fix: Disable the "erase datatype wrappers" optimization if the datatype implements any traits. feat: Allow the "erase datatype wrappers" optimization if the only fields in the datatype are ghost field[https://github.com/dafny-lang/dafny/pull/5234](https://togithub.com/dafny-lang/dafny/pull/5234)ull/5234) - Fix the default string value emitted for JavaScript ([https://github.com/dafny-lang/dafny/pull/5239](https://togithub.com/dafny-lang/dafny/pull/5239)) ### [`v4.5.0`](https://togithub.com/dafny-lang/dafny/blob/HEAD/RELEASE_NOTES.md#450) #### New features - Add the option `--include-test-runner` to `dafny translate`, to enable getting the same result as `dafny test` when doing manual compilation. ([https://github.com/dafny-lang/dafny/pull/3818](https://togithub.com/dafny-lang/dafny/pull/3818)) - - Fix: verification in the IDE no longer fails for iterators - Fix: the IDE now provides feedback when verification fails to run, for example due to a bad solver path - Fix: let the IDE correctly use the solver-path option when it's specified in a project file - Feat: improve the order of verification diagnostics emitted by the Dafny CLI, so that they now always follow the line order of the program. [https://github.com/dafny-lang/dafny/pull/4798](https://togithub.com/dafny-lang/dafny/pull/4798)ull/4798) - - Add an option `--filter-position` to the `dafny verify` command. The option filters what gets verified based on a source location. The location is specified as a file path suffix, optionally followed by a colon and a line number. For example, `dafny verify dfyconfig.toml --filter-position=source1.dfy:5` will only verify things that range over line 5 in the file `source1.dfy`. In combination with \`\`--isolate-assertions` , individual assertions can be verified by filtering on the line that contains them. When processing a single file, the filename can be skipped, for example: `dafny verify MyFile.dfy --filter-position=:23\` - Add an option `--filter-symbol` to the `dafny verify` command, that only verifies symbols whose fully qualified name contains the given argument. For example, `dafny verify dfyconfig.toml --filter-symbol=MyModule` will verify everything inside `MyModule`. - The option `--boogie-filter` has been removed in favor of --filter-symbol [https://github.com/dafny-lang/dafny/pull/4816](https://togithub.com/dafny-lang/dafny/pull/4816)ull/4816) - Add a `json` format to those supported by `--log-format` and `/verificationLogger`, for producing thorough, machine readable logs of verification results. ([https://github.com/dafny-lang/dafny/pull/4951](https://togithub.com/dafny-lang/dafny/pull/4951)) - - Flip the behavior of `--warn-deprecation` and change the name to `--allow-deprecation`, so the default is now false, which is standard for boolean options. - When using `--allow-deprecation`, deprecated code is shown using tooltips in the IDE, and on the CLI when using `--show-tooltips`. - Replace the option `--warn-as-error` with the option `--allow-warnings`. The new option, when false, the default value, causes Dafny to stop generating executable output and return a failure exit code, when warnings occur in the program. Contrary to the previous `--warn-as-error` option, warnings are always reported as warnings. - During development, users must use `dafny run --allow-warnings` if they want to run their Dafny code when it contains warnings. - If users have builds that were passing with warnings, they have to add `--allow-warnings` to allow them to still pass. - If users upgrade to a new Dafny version, and are not using `--allow-warnings`, and do not want to migrate off of deprecated features, they will have to use `--allow-deprecation`. - When using the legacy CLI, the option /warningsAsErrors now has the behavior of --allow-warnings=false - A doo file that was created using `--allow-warnings` causes a warning if used by a consumer that does not use it. [https://github.com/dafny-lang/dafny/pull/4971](https://togithub.com/dafny-lang/dafny/pull/4971)ull/4971) - The new `{:contradiction}` attribute can be placed on an `assert` statement to indicate that it forms part of an intentional proof by contradiction and therefore shouldn't be warned about when `--warn-contradictory-assumptions` is turned on. ([https://github.com/dafny-lang/dafny/pull/5001](https://togithub.com/dafny-lang/dafny/pull/5001)) - Function and method parameters and return types, and datatype constructor arguments, can now have attributes. By default, there are no attributes that Dafny recognizes in these positions, but custom back-ends can use this feature to get extra information from the source files. ([https://github.com/dafny-lang/dafny/pull/5032](https://togithub.com/dafny-lang/dafny/pull/5032)) - Under the CLI option `--general-newtypes`, the base type of a `newtype` declaration can now be (`int` or `real`, as before, or) `bool`, `char`, or a bitvector type. `as` and `is` expressions now support more types than before. In addition, run-time type tests are supported for `is` expressions, provided type parameters are injective (as was already required) and provided the constraints of any subset type or newtype is compilable. Note, although both `as` and `is` allow many more useful cases than before, using `--general-newtypes` will also forbid some unusual cases that were previously allowed. Any such case that is now forbidden can still be done by doing the `as`/`is` via `int`. [https://github.com/dafny-lang/dafny/pull/5061](https://togithub.com/dafny-lang/dafny/pull/5061)5061) - Allow newtype declarations to be based on set/iset/multiset/seq. ([https://github.com/dafny-lang/dafny/pull/5133](https://togithub.com/dafny-lang/dafny/pull/5133)) #### Bug fixes - Fixed crash caused by cycle in type declaration ([https://github.com/dafny-lang/dafny/pull/4471](https://togithub.com/dafny-lang/dafny/pull/4471)) - Fix resolution of unary minus in new resolver ([https://github.com/dafny-lang/dafny/pull/4737](https://togithub.com/dafny-lang/dafny/pull/4737)) - The command line and the language server now use the same counterexample-related Z3 options. ([https://github.com/dafny-lang/dafny/pull/4792](https://togithub.com/dafny-lang/dafny/pull/4792)) - Dafny no longer crashes when required parameters occur after optional ones. ([https://github.com/dafny-lang/dafny/pull/4809](https://togithub.com/dafny-lang/dafny/pull/4809)) - Use defensive coding to prevent a crash in the IDE that could occur in the context of code actions. ([https://github.com/dafny-lang/dafny/pull/4818](https://togithub.com/dafny-lang/dafny/pull/4818)) - Fix null-pointer problem in new resolver ([https://github.com/dafny-lang/dafny/pull/4875](https://togithub.com/dafny-lang/dafny/pull/4875)) - Fixed a crash that could occur when a case body of a match that was inside a loop, had a continue or break statement. ([https://github.com/dafny-lang/dafny/pull/4894](https://togithub.com/dafny-lang/dafny/pull/4894)) - Compile run-time constraint checks for newtypes in comprehensions ([https://github.com/dafny-lang/dafny/pull/4919](https://togithub.com/dafny-lang/dafny/pull/4919)) - Fix null dereference in constant-folding invalid string-indexing expressions ([https://github.com/dafny-lang/dafny/pull/4921](https://togithub.com/dafny-lang/dafny/pull/4921)) - Check for correct usage of type characteristics in specifications and other places where they were missing. This fix will cause build breaks for programs with missing type characteristics (like `(!new)` and `(0)`). Any such error message is accompanied with a hint about what type characterics need to be added where. [https://github.com/dafny-lang/dafny/pull/4928](https://togithub.com/dafny-lang/dafny/pull/4928)4928) - Initialize additional fields in the AST ([https://github.com/dafny-lang/dafny/pull/4930](https://togithub.com/dafny-lang/dafny/pull/4930)) - Fix crash when a function/method with a specification is overridden in an abstract type. ([https://github.com/dafny-lang/dafny/pull/4954](https://togithub.com/dafny-lang/dafny/pull/4954)) - Fix crash for lookup of non-existing member in new resolver ([https://github.com/dafny-lang/dafny/pull/4955](https://togithub.com/dafny-lang/dafny/pull/4955)) - Fix: check that subset-type variable's type is determined (resolver refresh). Fix crash in verifier when there was a previous error in determining subset-type/newtype base type. Fix crash in verifier when a subset type has no explicit `witness` clause and has a non-reference trait as its base type. [https://github.com/dafny-lang/dafny/pull/4956](https://togithub.com/dafny-lang/dafny/pull/4956)4956) - The `{:rlimit N}` attribute, which multiplied `N` by 1000 before sending it to Z3, is deprecated in favor of the `{:resource_limit N}` attribute, which can accept string arguments with exponential notation for brevity. The `--resource-limit` and `/rlimit` flags also now omit the multiplication, and the former allows exponential notation. ([https://github.com/dafny-lang/dafny/pull/4975](https://togithub.com/dafny-lang/dafny/pull/4975)) - Allow a datatype to depend on traits without being told "datatype has no instances" ([https://github.com/dafny-lang/dafny/pull/4997](https://togithub.com/dafny-lang/dafny/pull/4997)) - Don't consider `:= *` to be a definite assignment for non-ghost variables of a `(00)` type ([https://github.com/dafny-lang/dafny/pull/5024](https://togithub.com/dafny-lang/dafny/pull/5024)) - Detect the same ghost usage in initializing assignments as in other expressions. The effect of this fix is to allow more iset/imap comprehensions to be compiled. Also, report errors if the LHS of `:=` in compiled `map`/`imap` comprehensions contains ghosts. [https://github.com/dafny-lang/dafny/pull/5041](https://togithub.com/dafny-lang/dafny/pull/5041)5041) - Escape names of nested modules in C# and Java ([https://github.com/dafny-lang/dafny/pull/5049](https://togithub.com/dafny-lang/dafny/pull/5049)) - A parent trait that is a reference type can now be named via `import opened`. Implicit conversions between a datatype and its parent traits no longer crashes the verifier. (Dis)equality expressions of a (co)datatype and its parent traits no longer crashes the verifier. [https://github.com/dafny-lang/dafny/pull/5058](https://togithub.com/dafny-lang/dafny/pull/5058)5058) - Fixed support for newtypes as sequence comprehension lengths in Java ([https://github.com/dafny-lang/dafny/pull/5065](https://togithub.com/dafny-lang/dafny/pull/5065)) - Don't emit an error message for a `function-by-method` with unused type parameters. ([https://github.com/dafny-lang/dafny/pull/5068](https://togithub.com/dafny-lang/dafny/pull/5068)) - The syntax of a predicate definition must always include parentheses. ([https://github.com/dafny-lang/dafny/pull/5069](https://togithub.com/dafny-lang/dafny/pull/5069)) - Termination override check for certain non-reference trait implementations ([https://github.com/dafny-lang/dafny/pull/5087](https://togithub.com/dafny-lang/dafny/pull/5087)) - Malformed Python code for some functions involving lambdas ([https://github.com/dafny-lang/dafny/pull/5093](https://togithub.com/dafny-lang/dafny/pull/5093)) - Let verifier understand opaque function overrides, supporting both when the overridden function is opaque and non-opaque. Revealing such a function for one overriding type has the effect of revealing it for all overriding types. Also, forbid the case where a function is opaque in a parent trait and the function override is not opaque. (Previously, this had caused a crash.) [https://github.com/dafny-lang/dafny/pull/5111](https://togithub.com/dafny-lang/dafny/pull/5111)5111) ### [`v4.4.0`](https://togithub.com/dafny-lang/dafny/blob/HEAD/RELEASE_NOTES.md#440) #### New features - Reads clauses on method declarations are now supported when the `--reads-clauses-on-methods` option is provided. The `{:concurrent}` attribute now verifies that the `reads` and `modifies` clauses are empty instead of generating an auditor warning. [https://github.com/dafny-lang/dafny/pull/4440](https://togithub.com/dafny-lang/dafny/pull/4440)4440) - Added two new options, `--warn-contradictory-assumptions` and `--warn-redundant-assumptions`, to detect potential problems with specifications that indicate that successful verification may be misleading. These options are currently hidden because they may occasionally produce false positives in cases where proofs are so trivial that the solver never does work on them. ([https://github.com/dafny-lang/dafny/pull/4542](https://togithub.com/dafny-lang/dafny/pull/4542)) - Verification of the `{:concurrent}` attribute on methods now allows non-empty `reads` and `modifies` clauses with the `{:assume_concurrent}` attribute. ([https://github.com/dafny-lang/dafny/pull/4563](https://togithub.com/dafny-lang/dafny/pull/4563)) - Implemented support for workspace/symbol request to allow IDE navigation by symbol. ([https://github.com/dafny-lang/dafny/pull/4619](https://togithub.com/dafny-lang/dafny/pull/4619)) - The new `--verification-coverage-report` flag to `dafny verify` creates an HTML report highlighting which portions of the program were and were not necessary for verification. The format is the same as for `dafny generate-tests --coverage-report` and files from the two commands can be merged. ([https://github.com/dafny-lang/dafny/pull/4625](https://togithub.com/dafny-lang/dafny/pull/4625)) - Built-in types such as the `nat` subset type, tuples, arrows, and arrays are now pre-compiled into each backend's runtime library, instead of emitted on every call to `dafny translate`, to avoid potential duplicate definitions when translating components separately.

For example, merging coverage reports from test generation and verification using the option `--only-label NotCovered` will highlight only the regions not covered by either testing or verification. ([https://github.com/dafny-lang/dafny/pull/4673](https://togithub.com/dafny-lang/dafny/pull/4673)) - The Dafny distribution now includes standard libraries, available with the `--standard-libraries` option.

([https://github.com/dafny-lang/dafny/pull/4681](https://togithub.com/dafny-lang/dafny/pull/4681)) - The new `--coverage-report` flag to `dafny run` and `dafny test` creates an HTML report highlighting which portions of the program were executed at runtime. ([https://github.com/dafny-lang/dafny/pull/4755](https://togithub.com/dafny-lang/dafny/pull/4755)) - Enable turning nonlinear arithmetic on or off on a per-module basis, using the attribute `{:disable-nonlinear-arithmetic}`, which optionally takes the value false to enable nonlinear arithmeti[https://github.com/dafny-lang/dafny/pull/4773](https://togithub.com/dafny-lang/dafny/pull/4773)ull/4773) - Let the IDE provide code navigation in situations where the program parses but has resolution errors. Note that this only works for modules whose dependency tree does not have errors, or modules who contain errors themselves, but not for modules whose dependencies contain errors. ([https://github.com/dafny-lang/dafny/pull/4855](https://togithub.com/dafny-lang/dafny/pull/4855)) #### Bug fixes - Ensures that computing the set of values or items of map can only be done if the type of the range supports equality.

([https://github.com/dafny-lang/dafny/pull/4530](https://togithub.com/dafny-lang/dafny/pull/4530)) - Fix a bug that prevented certain types of lemma to be verified in the IDE ([https://github.com/dafny-lang/dafny/pull/4607](https://togithub.com/dafny-lang/dafny/pull/4607)) - Dot completion now works on values the type of which is a type synonym. ([https://github.com/dafny-lang/dafny/pull/4635](https://togithub.com/dafny-lang/dafny/pull/4635)) - Fix a case where the document symbol API would return incorrect data when working on a file with parse errors ([https://github.com/dafny-lang/dafny/pull/4675](https://togithub.com/dafny-lang/dafny/pull/4675)) - Emit less nested target code in match-case expressions (nice for readability, and necessary for Java) ([https://github.com/dafny-lang/dafny/pull/4683](https://togithub.com/dafny-lang/dafny/pull/4683)) - Ghost diagnostics are now correctly updated when they become empty ([https://github.com/dafny-lang/dafny/pull/4693](https://togithub.com/dafny-lang/dafny/pull/4693)) - Enable verification options that are configured in a Dafny project file, to be picked up by the Dafny language server ([https://github.com/dafny-lang/dafny/pull/4703](https://togithub.com/dafny-lang/dafny/pull/4703)) - Prevent double-counting of covered/uncovered lines in test coverage reports ([https://github.com/dafny-lang/dafny/pull/4710](https://togithub.com/dafny-lang/dafny/pull/4710)) - fix: correction of type inference for default expressions ([https://github.com/dafny-lang/dafny/pull/4724](https://togithub.com/dafny-lang/dafny/pull/4724)) - The new type checker now also supports static reveals for instance functions ([https://github.com/dafny-lang/dafny/pull/4733](https://togithub.com/dafny-lang/dafny/pull/4733)) - Resolve :- expressions with void outcomes in new resolver ([https://github.com/dafny-lang/dafny/pull/4734](https://togithub.com/dafny-lang/dafny/pull/4734)) - Crash in the resolver on type parameters of opaque functions in refined modules ([https://github.com/dafny-lang/dafny/pull/4768](https://togithub.com/dafny-lang/dafny/pull/4768)) - Fix error messages being printed after their context snippets ([https://github.com/dafny-lang/dafny/pull/4787](https://togithub.com/dafny-lang/dafny/pull/4787)) - Override checks no longer crashing when substituting type parameters and equality ([https://github.com/dafny-lang/dafny/pull/4812](https://togithub.com/dafny-lang/dafny/pull/4812)) - Removed one cause of need for restarting the IDE.
