## [Notable Changes in NSS 3.36.1](#notable_changes_in_nss_3.36.1)

:::{container}

- In NSS version 3.35 the iteration count in optimized builds, which is used for password based
  encryption algorithm related to encrypted PKCS#7 or PKCS#12 data, was increased to one million
  iterations. That change had caused an interoperability regression with operating systems that
  are limited to 600 K iterations. NSS 3.36.1 has been changed to use the same 600 K limit.

## [Compatibility](#compatibility)

:::{container}
NSS 3.36.1 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 3.36.1 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.
