1.15 release notes #38966

brson · Jan 10, 2017

Lots of good stuff this release!

Perf graphs: https://goo.gl/KSVFvF, https://goo.gl/K98g8M, https://goo.gl/H1gSoz, https://goo.gl/yZBV2p, https://goo.gl/ltURbb. Not much change 😿

+* [Fix `extern "aapcs" fn` ABI][37814]
+* [The `-C no-stack-check` flag is deprecated][37637]. It does nothing.


Wrong issue/PR number. This refers to an issue titled "Using $crate with a proc macro"

+* [Support creation of anonymous pipes on WinXP/2k][37677]
+* [`copy_from_slice` is optimized for small copies][37573]


Ah this PR didn't actually change copy_from_slice (but changed impl Read for &[u8]), so that it special cases the single byte read case.

+* [Use small vectors in type walker][37760]
+* [Avoid unnecessary `mk_ty` calls in `Ty::super_fold_with`][37705]


As written this seems identical to the change four bullet points up. Granted, the PRs do basically the same thing, but throwing in a "more" somewhere would help — and indeed the linked PR is titled "Avoid more unnecessary ...".

Maybe add a note about the upcoming struct reorder by @camlorn ?

Once Peekable returns None it always does

This should be: if peekable peeks a None, it will return that same None in peek or next without querying the underlying iterator. Peekable is still not fused.

brson · Jan 10, 2017

All comments addressed. Thanks for review.

@est31 re struct reordering, in these I don't mention any work in progress, only what's usable on stable.

I'm not sure whether this is accurate for the 1.15 release. PR #38401 was merged after 1.15 branched off. PR #37702 was only about a preview.

@jackpot51 @ticki is this okay?

Hm, yeah. Maybe we should wait until the next release for this bullet.

"with the brace" sounds weird. "with curly braces"?

The link target is right but the label is wrong (but it matches the link, so this doesn't actually matter).

It is just custom derive, not "including" custom derive, right?

I don't know the details I'm afraid, but I'll say that.

The link for "Rust supports the MSP430" seems to be formatted incorrectly.
