## [Notable Changes in NSS 3.27.2](#notable_changes_in_nss_3.27.2)

:::{container}
The `SSL_SetTrustAnchors()` function is used to set the distinguished names that an NSS server
includes in its TLS CertificateRequest message. If this function is not used, NSS will include
the distinguished names for all trust anchors installed in the database. This can be a lengthy
list.

Previous versions of NSS leaked the memory used to store distinguished names when
`SSL_SetTrustAnchors()` was used. This release fixes that error.

:::

## [Compatibility](#compatibility)

:::{container}
NSS 3.27.2 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 3.27.2 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.
