`Notable Changes in NSS 3.27 <#notable_changes_in_nss_3.27>`__
--------------------------------------------------------------

- *UPDATE 2016-10-02:*
- The maximum TLS version supported has been increased to TLS 1.3 (draft).
- Although the maximum TLS version enabled by default is still TLS 1.2, there are
applications that query the list of TLS protocol versions supported by NSS, and enable all
supported versions. For those applications, updating to NSS 3.27 may result in TLS 1.3
(draft) to be enabled.
- The TLS 1.3 (draft) protocol can be disabled, by defining symbol NSS_DISABLE_TLS_1_3 when
building NSS.
- NPN can not be enabled anymore.
- Hard limits on the maximum number of TLS records encrypted with the same key are enforced.
- Disabled renegotiation in DTLS.
- The following CA certificates were **Removed**

This Bugzilla query returns all the bugs fixed in NSS 3.27:
`Compatibility <#compatibility>`__
----------------------------------
.. container::
NSS 3.27 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 3.27 shared libraries
without recompiling or relinking. 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.
