Dear all,

Network Security Services (NSS) 3.93 was released on 25 August 2023.

The HG tag is NSS_3_93_RTM. This version of NSS requires NSPR 4.35 or newer.

NSS 3.93 source distributions are available on ftp.mozilla.org for
secure HTTPS download:


- Bug 1849471 - Update zlib in NSS to 1.3.
- Bug 1848183 - softoken: iterate hashUpdate calls for long inputs.
- Bug 1813401 - regenerate NameConstraints test certificates.

NSS 3.93 shared libraries are backwards-compatible with all older NSS
3.x shared libraries. A program linked with older NSS 3.x shared
libraries will work with this new version of the 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 at
