NSS 3.27 set this value on by default, allowing TLS 1.3 (draft) to be + disabled using NSS_DISABLE_TLS_1_3, although the maximum version used by default remained TLS + 1.2. + + However, some applications query the list of protocol versions that are supported by the NSS + library, enabling all supported TLS protocol versions. Because NSS 3.27 enabled compilation of + TLS 1.3 (draft) by default, it caused those applications to enable TLS 1.3 (draft). This resulted + in connectivity failures, as some TLS servers are version 1.3 intolerant, and failed to negotiate + an earlier TLS version with NSS 3.27 clients. + + NSS 3.27.1 once again requires NSS_ENABLE_TLS_1_3 to be deliberately set to enable TLS 1.3 + (draft). + +.. _bugs_fixed_in_nss_3.27.1: + +`Bugs fixed in NSS 3.27.1 <#bugs_fixed_in_nss_3.27.1>`__ +-------------------------------------------------------- + +.. container:: + + - The following bug has been fixed in NSS 3.27.1: `Re-disable TLS 1.3 by + default <https://bugzilla.mozilla.org/show_bug.cgi?id=1306985>`__ + +`Compatibility <#compatibility>`__ +---------------------------------- + +.. container:: + + NSS 3.27.1 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 3.27.1 shared libraries + without recompiling or relinking.
