Dear all,

Network Security Services (NSS) 3.64 was released on April 15th, 2021.

The HG tag is NSS_3_64_RTM. NSS 3.64 requires NSPR 4.30 or newer.

NSS 3.64 source distributions are available on ftp.mozilla.org for secure HTTPS download: https://ftp.mozilla.org/pub/mozilla.org/security/nss/releases/NSS_3_64_RTM/src/

Bugs fixed in NSS 3.64:
* Bug 1705286 - Properly detect mips64.
* Bug 1687164 - Introduce NSS_DISABLE_CRYPTO_VSX and disable_crypto_vsx.
* Bug 1698320 - replace __builtin_cpu_supports("vsx") with ppc_crypto_support() for clang.
* Bug 1613235 - Add POWER ChaCha20 stream cipher vector acceleration.

NSS 3.64 shared libraries are backward compatible with all older NSS 3.x shared libraries.
A program linked with older NSS 3.x shared libraries will work with NSS 3.64 shared libraries
without recompiling or relinking. Furthermore, applications that restrict their use of NSS APIs
to the functions listed in NSS Public Functions will remain compatible with future versions
of the NSS shared libraries.

Bugs discovered should be reported by filing a bug report with bugzilla.mozilla.org (product NSS).

The release notes will be available at:

-- Notes: 
We had to release 3.63.1 on April 6th in order to temporarily suspend a CA change from 3.63
that would have caused a breakage of Firefox 88. (Bug 1703090)
