v0.29.0

What's Changed

In this release: 5 new lints, one fixed false-positive, and assorted UX improvements.

This is the last release to support Rust 1.71-1.73. Future releases will require Rust 1.74+ both to install (MSRV) and at runtime.

Hat-tip to everyone that came to check out my talk on cargo-semver-checks at FOSDEM 2024! We even got a chance to pair-program a few lints in the hallway after my talk: #649 with @rubdos, and #650 with @ehiggs.

Unfortunately, the FOSDEM recording had an AV glitch and lost ~10min of audio and video. But all is not lost!

• If you're in the Boston area, come to the Boston Rust meetup this Wednesday (Feb 21) where I'll again talk about cargo-semver-checks!
• I'm going to re-record the missing parts and post a new video, so follow me on Mastodon, Twitter, or Bluesky.

New lints:

• exported_function_changed_abi by @ehiggs (#650)
• repr_packed_added by @jw013 (#666)
• repr_packed_removed by @jw013 (#666)
• struct_pub_field_now_doc_hidden by @rubdos (#649)
• trait_no_longer_object_safe (Rust 1.77+ only) by @devanbenz (#659)

False positives fixed:

• trait_method_unsafe_removed no longer triggers on traits sealed using the pub-in-priv supertrait technique. Contributed by @yottalogical in #614.

Miscellaneous:

• Support checking rlib, dylib, and staticlib Rust library types, by @obi1kenobi (#662, #663, #664).
• Improve diagnostic messages when a crate fails to build, by @obi1kenobi (#656, #658)
