Sorry I have been absent, I'll have a look tomorrow.

@pitdicker no worries! Friendly ping?

I am trying to understand the cause of the dependency resolution issue on 1.57.0. It seems to be because ahash 0.7.6 is yanked last week. We used to have 0.7.6 in the dependency tree.

All versions before 0.7.7 have a vulnerability and are yanked: tkaitchuck/aHash#163, fixed in PR tkaitchuck/aHash#175.
But it also pulls in a fix for AVR that updates once_cell to 1.13.1.

Maybe we should get in contact in tkaitchuck/aHash#174 or some other issue before bumping the MSRV?

[djc]

I think it's probably because the latest ahash 0.7 release includes use of specific dep: features, which cause Cargo before 1.60 to fail parsing the manifest (but I didn't actually check).

[djc]

I feel like it's okay to get to 1.60 at this point. Current Debian stable has 1.63.

[pitdicker]

Okay, I'm the last to complain about bumping the MSRV 😄. and Debian is pretty much the one to care about, right?

Do you also want to update the documentation in README.md and lib.rs?

[pitdicker]

If we bump to 1.61 we can start making the methods on DateTime const, and remove the workaround from 6b3a314.

[djc]

Added the README and crate root docs changes and bumped to 1.61.

Sorry, in my memory this was already merged.
