REL: PRs that may need release notes

[charris]

In order to start preparing for the 1.20.0 I thought I'd check for missing release notes. This is a generated starting list for enhancements, some entries may be spurious and I've omitted the SIMD work which I think falls under performance. I will later add a list for deprecations. I'm thinking we need another tag, maybe NEW, to mark true additions.
