Rust Just Failed an Important Test
To clarify this a bit:
1. The widely used Time crate had some code which converted to an unspecified type. The code then converted this again in a following line. Because there was only a single possible (identity) conversion, this code was a noop. Regardless this was fixed in [email protected] (released in April 9, 2024). [1]
2. Rust 1.80 (released July 27, 2024) introduced a new trait implementations that made the second conversion now cause the first conversions to have two possible inferences. [2]
3. Rust packages that upgraded the compiler to 1.80.0, but used a version of the time crate prior to 0.1.35 fail to build the time dependency. This is mitigated by the fact that 0.1.35 is a semver compatible update, which just requires running cargo update to use.

[2]: https://blog.rust-lang.org/2024/07/25/Rust-1.80.0.html#stabi...
Something that would be neat to see from Rust here would be a way to measure the impact of these sorts of compiler and dependency bumps in order to reduce the blast radius of this sort of thing. Ideally being able to say "this change requires X devs to do process which cost Y minutes, so it's worth investing Z minutes to avoid / document it". I often want to make public API changes to a library I maintain, but the best tool I have for understanding who those changes will affect is often a GitHub search for code.

Getaddrinfo() on glibc calls getenv(), oh boy
The problem is that this effects higher languages too, because they often build on libc. And on some OSes, they don't have a choice, because the system call interface is unstable and/or undocumented).
For example in rust, multiple time libraries were found to be unsound if `std::env::set_env` was ever called from a multi-threaded program. See:
https://github.com/time-rs/time/issues/293 and https://github.com/chronotope/chrono/issues/499
https://github.com/rust-lang/rust/issues/27970
https://github.com/rust-lang/rust/issues/90308
- The time crate has officially adopted an N-2 MSRV policy for end-user improvements and an N-4 MSRV policy for internal improvements.

Simple, fast and safety alternative for unzip
On that note, it would also be good to configure cargo-deny so that a CI pipeline and any maintainer can easily audit the current dependency versions. Sometimes CVEs require a new major semver (looking at you, time 0.1.x and thus chrono 0.4.x), so it's not enough to rely on people installing the tool with semver-compatible updates. Automatically auditing dependencies is really important, and given how easy cargo-deny makes it, I don't think many projects have any excuse not to configure it.

Hifitime 3.5.0: time.rs and chrono alternative, only more precise, formally verified, and used in scientific and engineering programs
I've come to understand that correct support for leap seconds for time computations cannot be implemented in a reliable and globally consistent manner. Here is a GitHub discussion that touches on this.

What lightweight date/time library to use? [2022 edition]
I'm not fully aware of all the history but here's what I think happened: time 0.1 was originally a minimal wrapper around libc time functions, maintained by Alex Crichton. (I seem to remember it may have been part of the std library before 1.0, but I'm not sure about that part.) In August of 2016 it was declared to no longer be actively maintained, with the README stating bugs would still get fixed.
