Re: PG 16 draft release notes ready

Hi Bruce,

> Add support for SSE2 (Streaming SIMD Extensions 2) vector operations on x86-64 architectures (John Naylor)

> Add support for Advanced SIMD (Single Instruction Multiple Data) (NEON) instructions on ARM architectures (Nathan Bossart)

Nit: It's a bit odd that SIMD is spelled out in only the Arm entry, and perhaps expanding the abbreviations can be left out.

We can leave out the architecture here (see below). Typo: "array searches"

All the above seem appropriate for the "source code" section, but the following entries might be better in the "performance" section:

> Allow ASCII string detection to use vector operations on x86-64 architectures (John Naylor)
> Allow JSON string processing to use vector operations on x86-64 architectures (John Naylor)

Arm as well. For anything using 16-byte vectors the two architectures are equivalently supported. For all the applications, I would just say "vector" or "SIMD".

And here maybe /processing/parsing/.

When moved to the performance section, it would be something like "improve scalability when a large number of write transactions are in progress".
