This PR was rebased onto a different master commit. Here's a range-diff highlighting what actually changed.

Rebasing is a normal part of keeping PRs up to date, so no action is needed—this note is just to help reviewers.

Turbo87 · 2025-12-20T14:37:19Z

since @epage asked: the crates.io team talked about the pubtime field in one of our team meetings a couple of weeks ago and there were no objections to introducing it :)

rust-rfcbot · 2025-12-26T15:20:20Z

The final comment period, with a disposition to merge, as per the review above, is now complete.

As the automated representative of the governance process, I would like to thank the author for their work and everyone else who contributed.

Congratulations, folks. We have t-cargo and t-crates-io signed off of this index pubtime field.

Ten days FCP has passed. This is going to be merge soon. Expect to be stabilized in 1.94.

The top-level include config key allows loading additional config files, enabling better organization, sharing, and management of Cargo configurations across projects and environments. [docs] (https://doc.rust-lang.org/nightly/cargo/reference/config.html#including-extra-configuration-files) [#16284] (rust-lang/cargo#16284) - Stabilize the pubtime field in registry index. This records when a crate version was published and enables time-based dependency resolution in the future. Note that crates.io will gradually backfill existing packages when a new version is published. Not all crates have pubtime yet. [#16369] (rust-lang/cargo#16369) [#16372] (rust-lang/cargo#16372) - Cargo now parses [TOML v1.1](https://toml.io/en/v1.1.0) for manifests and configuration files. Note that using these features in Cargo.toml will raise your development MSRV, but the published manifest remains compatible with older parsers. [#16415] (rust-lang/cargo#16415) - [Make `CARGO_BIN_EXE_<crate>` available at runtime ] (rust-lang/cargo#16421) Compatibility Notes ------------------- - [Forbid freely casting lifetime bounds of `dyn`-types] (rust-lang/rust#136776) - [Make closure capturing have consistent and correct behaviour around patterns] (rust-lang/rust#138961) Some finer details of how precise closure captures get affected by pattern matching have been changed. In some cases, this can cause a non-move closure that was previously capturing an entire variable by move, to now capture only part of that variable by move, and other parts by borrow. This can cause the borrow checker to complain where it previously didn't, or cause `Drop` to run at a different point in time. - [Standard library macros are now imported via prelude, not via injected ` #[macro_use]`] (rust-lang/rust#139493) This will raise an error if macros of the same name are glob imported. For example if a crate defines their own `matches` macro and then glob imports that, it's now ambiguous whether the custom or standard library `matches` is meant and an explicit import of the name is required to resolve the ambiguity. One exception is `core::panic` and `std::panic`, if their import is ambiguous a new warning ([`ambiguous_panic_imports`] (rust-lang/rust#147319)) is raised. This may raise a new warning ([`ambiguous_panic_imports`] (rust-lang/rust#147319)) on `#![no_std]` code glob importing the std crate. Both `core::panic!` and `std::panic!` are then in scope and which is used is ambiguous. - [Don't strip shebang in expression-context `include!(…)`s] (rust-lang/rust#146377) This can cause previously working includes to no longer compile if they included files which started with a shebang. - [Ambiguous glob reexports are now also visible cross-crate] (rust-lang/rust#147984) This unifies behavior between local and cross-crate errors on these exports, which may introduce new ambiguity errors. - [Don't normalize where-clauses before checking well-formedness] (rust-lang/rust#148477) - [Introduce a future compatibility warning on codegen attributes on body-free trait methods] (rust-lang/rust#148756) These attributes currently have no effect in this position. - [On Windows `std::time::SystemTime::checked_sub_duration` will return `None` for times before the Windows epoch (1/1/1601)] (rust-lang/rust#148825) - [Lifetime identifiers such as `'a` are now NFC normalized] (rust-lang/rust#149192). - [Overhaul filename handling for cross-compiler consistency] (rust-lang/rust#149709) Any paths emitted by compiler now always respect the relative-ness of the paths and `--remap-path-prefix` given originally. One side-effect of this change is that paths emitted for local crates in Cargo (path dependencies and workspace members) are no longer absolute but relative when emitted as part of a diagnostic in a downstream crate. Internal Changes ---------------- These changes do not affect any public interfaces of Rust, but they represent significant improvements to the performance or internals of rustc and related tools. - [Switch to `annotate-snippets` for error emission] (rust-lang/rust#150032) This should preserve mostly the same outputs in rustc error messages.
