This Month in Hax: April 2025

In April, we successfully merged 38 pull requests!

Thanks @Nadrieril, for pinning a more recent nightly version of the Rust compiler (#1391). Nadrieril also continued making the frontend more robust and complete with work on constants #1402, #1420, #1429) and item's children (#1412).

@W95Psp worked on hax-lib with improved support for writing f* lemmas in rust (#1428), and fstar post-processing with tactics (#1437).

I worked on while loops which now support invariants and variants (to prove termination) in #1375

We also worked on various improvements like removing deprecated dependencies used by hax-lib (#1385 and #1394), some ProVerif backend workarounds by @jschneider-bensch (#1360, #1401 and #1406), and multiple f* core lib additions.

Stay tuned for more updates next month!
