cargo-msrv v0.16.0-beta.1

(Changelog for 0.16.0 is in progress, and may be incomplete)

Added

• Subcommand cargo msrv verify now supports setting a custom Rust version via the --rust-version <VERSION> argument,
  which can be used to check for a crate's compatibility against a specific Rust version.
• Added flag --write-msrv to cargo msrv (find), which upon finding the MSRV writes its value to the Cargo manifest.
• Added option to refer to a specific crate using its Cargo manifest (with --manifest-path) instead of its path (with --path)
• Added a 'minimal' output option intended for machine-readable use when full json output is undesirable.

Changed

• CLI options are now grouped.
• Option --min <version> now also accepts two component semver major.minor versions, in addition to full three component (strict) SemVer versions, and edition specifiers like "2015", "2018" and "2021".
• Option --max <version> now also accepts two component semver major.minor versions, in addition to full three component (strict) SemVer versions.
• The rust-releases index is now only fetched for subcommands which depend on it.
• Renamed --toolchain-file to --write-toolchain-file to emphasise that the toolchain-file is an output.
• Subcommand cargo msrv set will now default to writing a regular TOML table for the metadata MSRV fallback value, instead of an inline table.
• The rust-toolchain file will now be overwritten if a rust-toolchain file was already present.

Fixed

• Subcommand cargo msrv set will now return an error when the Cargo manifest solely consists of a virtual workspace.
• The program will no longer return an unformatted message when a command failed and the output format was set to json.
• Fix issue where reading the fallback MSRV from a TOML inline table was not possible.
• Fix an index out-of-bounds panic which occurred if the filtered Rust releases search space was empty

cargo-msrv v0.15.1

NB: Check the releases page to also find more recent beta releases.

0.15.1 - 2022-02-24

In this release a license generation step was fixed, which caused the automated binary builds to fail.
In addition, a Cargo feature toggle was added which adds a feature gate for the rust-dist release source of
the rust-releases crate. This allows people who build from source to build cargo-msrv without the default
features (i.e. without rust-dist), which reduces build time and binary size.

This release does not contain user-facing changes, hence the lack of changelog entries for this version.

cargo-msrv v0.15.0

0.15.0 - 2022-02-23

Added

• Flag --no-user-output which disables user output.
• Subcommand cargo msrv set, which can be used to write a given MSRV to the Cargo manifest.

Changed

• ⚠️ Breaking change: Changed default cargo-msrv (find) check command from cargo check --all to cargo check.
  • Revert to the old behaviour by running cargo-msrv with a custom check command: cargo msrv -- cargo check --all.

Removed

• ⚠️ Breaking change: Value void was removed as a valid format for the --output-format option.
  • Use new --no-user-output flag instead

Special thanks: @cschramm

cargo-msrv v0.14.2

0.14.2 - 2022-02-09

cargo-msrv v0.14.1

• Changed: Changed terminology from 'Determine MSRV' to 'Find MSRV' for top level cargo-msrv command.
• Added: Flag --linear to the top cargo-msrv command ('find msrv') to choose explicitly for the linear search strategy.
• Changed: The default search method is now bisect instead of linear. ⚠
• Added: Feedback messages printed after each check, allowing users to see why certain Rust versions are not compatible.
• Added: Flag --no-check-feedback which disables the feedback messages printed after each check.

cargo-msrv v0.13.0

• Added: Logging to a file (default) or the stdout for developer information; can also be disabled entirely
• Added: Output format option 'void', which disables user targeted output
• Changed: cargo-msrv now exits with a non-zero exit code on failure
• Changed: Clarify the reason when the program fails because of an IO error
• Added: Book covering cargo-msrv topics, and its subcommands
• Changed: Suggest package.rust-version is missing when MSRV can't be found in the Cargo manifest

cargo-msrv v0.12.0

0.12.0 - 2021-11-01

• Added subcommand list which lists the MSRV's of dependencies as specified by crate authors using the rust-version key.
• You can now also simply run cargo-msrv standalone, i.e. cargo-msrv instead of cargo msrv

Only list is available as a subcommand. The determine-msrv and verify-msrv commands have not been ported to subcommands yet, but are planned to.

Also of interest:

• migrate to toml_edit by @euclio in #162

cargo-msrv v0.11.1

0.11.1 - 2021-10-28

This release is equal to v0.11.0, except that the automated 'release build and packaging' task was fixed.
The release notes for v0.11.0 have been included below.

0.11.0 - 2021-10-28

• Added --release-source which allows users to select a rust-releases source. Thanks @pjsier
• A message is now shown to inform users when the index is being updated. Thanks @pjsier
• Verify can now also read and use the package.rust-version MSRV key in the Cargo.toml manifest.
• When the package.edition is set, the first release supporting this edition will now be set as the minimum version.
  This behaviour can be disabled by providing the --no-read-min-edition flag. Thanks @clanghout
