Even if it comes about one and a half months after the GStreamer 1.12.0 release, the 1.12.1 update is a small one that contains only bugfixes. These include improvements to the Meson build system, a fix for a memory leak on the gstptpclock related to the delay request message release, leaving the timeout source referenced. Leaks also appear to have been fixed in the registrychunks component under utils/, which were discovered in failed cases, and GStreamer 1.12.1 addresses incorrect escaping of the path in the gst_uri_construct function of the gsturi component. In GStreamer Base Plugins, they fixed a Playbin3 RTSP freeze that occurred at first frame and added introspection annotations for various navigation output parameters.
