+Subject: pipewiresink: use all the available dest memory when copying buffer
+
+When pipewiresink needs to copy data, it has to resize the destination
+buffer (to a smaller size) in order to send the correct data size to
+pipewire. When this dest buffer is reused later, it will still have
+this smaller size as its total size and the copy may discard data
+from upstream if the new upstream buffer is bigger than the last one
+that was copied on the same dest buffer.

+Subject: pipewiresink: release manually acquired buffers back to the pool
+
+When we manually acquire buffers from the pool, we never release them.
+But because gst_buffer_pool_acquire_buffer() adds a reference to the pool,
+this leaks the pool eventually.
+
+To fix this, just unref the buffer after it has been sent. This releases
+it back to the pool and unrefs the pool.
+
+This has no significant effect to the stream, since the underlying
+pw buffers are actually pooled in the pw_stream. It just prevents leaking.

-Subject: [PATCH] gst: Implement new pwaudio{src,sink} elements, based on
- GstAudioBase{Src,Sink}
-
-These are much more reliable elements to use for audio data.
-* GstAudioBaseSink provides a reliable clock implementation based
-  on the number of samples read/written
-* on the pipewire side we make sure to dequeue, fill and enqueue
-  a single buffer inside the process() function, which avoids
-  underruns
-
-Both elements share a common ringbuffer that actually implements
-the pipewire integration.

-Subject: [PATCH] module-access: add same-sec-label-mode
-
-This is a mode where the access module allows all clients that have
-the same security label as the pipewire daemon, and every other
-client is put on the restricted state.
-
-In systems that use SMACK security labels, such as AGL, this allows
-the session manager (which is spawned by pipewire, inheriting the
-same smack label) to have full access to all objects, while every
-other client is restricted and the session manager must decide
-what to do with it
-
-Note that while this option is configurable, there is no loss of
-security if this option is not set in the configuration. Clients
-that don't have the same security context will be considered to
-be flatpak clients because pipewire will not be able to open
-/proc/pid/cmdline. This however results in some unwanted error
-messages that may be confusing.

-
-Currently alsa_read and alsa_write assumes that all the frames committed
-using snd_pcm_mmap_commit are read or written, which is probably true.
-However, as it could be some corner cases add a warning to notice this
