## [Compatibility](#compatibility)

:::{container}
NSS 3.62 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 NSS 3.62 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.

## [Notes](#notes)

:::{container}
Due to changes to MDN, we have been notified that the NSS documentation will have to move off of
MDN. It is not fully clear yet, but the proposed solution is to move the documentation in-tree
(nss/docs), to the md/sphinx format, and have it either rendered as a sub-section of the Firefox
source docs or as a standalone website. More information will follow in the NSS 3.63 notes.

Regarding the Release day, in order to organize release process better and avoid issues, we will
likely move the release day to Thursdays. Please take a look at the release calendar for the
exact dates.
