cc rust-lang/rust#133210 @lcnr @rust-lang/types -- I expanded/reworded a bit the stub you had started for new trait solver in coherence, would definitely appreciate review to make sure I didn't get the details too wrong :)

cc @joshtriplett @rust-lang/cargo for the section on MSRV-aware resolver, I sort of semi-randomly came up with recommendations and general prose but very happy to replace it if there's something better or actual recommendations the team wants to offer :)

cc @rust-lang/opsem for the strict provenance section -- I tried to find a balance between copying in the whole contents of the standard library docs and referencing them, very open to changes though.

cc @rust-lang/release as well...

@Mark-Simulacrum I already spent some effort on Strict Provenance release notes in rust-lang/rust#131996, did you see that? I thought that is the intended place for such text.

Thanks, I had seen it previously but missed it when putting together the blog (just my bad). Copied that text in, it looks good to me, thanks for writing it up!

OK, I think that incorporates the feedback I have clear solutions for. I'm still not super happy with the header for the MSRV section, but I don't have any better ideas than the tweak I applied just now.
