+# PipeWire 1.1.81 (2024-05-16)
+
+This is the first 1.2 release candidate that is API and ABI
+compatible with previous 1.0.x releases.
+
+In addition to all the changes backported to 1.0.x, this release
+also contains some new features:
+
+## Highlights
+  - Support for asynchronous processing has been implemented. Nodes can choose
+    (or be forced) to be scheduled asynchronously. The graph will not wait for
+    the output of the node to continue processing but it will use the output
+    of the previous cycle (or silence) instead. This adds one cycle of latency
+    but it can avoid having some nodes blocking the processing graph. Non realtime
+    streams and filters now also use this asynchronous processing instead of
+    their own slightly broken version.
+  - The concept of node.sync-group was added. This groups nodes with overlapping
+    sync-group together when one of them sets the node.sync = true. This is now
+    used to make sure all nodes are scheduled together when JACK transport is
+    started so that they all see the same time.
+  - Config parsing errors are reported earlier and much better with line and
+    column numbers where the parsing started to fail.
+  - Add support for mandatory metadata when negotiation buffer parameters. This
+    can be used to only negotiate extra buffer planes when certain metadata is
+    negotiated. One use case is the explicit sync support that requires 2
+    extra fds for the timelines.
+  - Support was added for making and using multiple data-loops in the server
+    and clients. Support for CPU affinity and priorities was added to the
+    data-loops as well.
+  - The log topic debug levels can now be changed at runtime with metadata.
+    The log levels in the pulse server can be dynamically changed with a
+    /core message.
+  - The UCM conflicting devices patches were merged.
+
+
+## PipeWire
+  - snap support has been added.
+  - Implement async processing. (#3509)
+  - Support for explicit sync was added.
+  - Config parsing errors are reported earlier and much better.
+  - A -P option was added to provide extra properties to the context. This can be
+    used to enable some features that use rules.
+  - properties.rules was added to enhance properties based on some rules.
+    This deprecates the vm.overrides.
+  - Support was added for security-context. This makes it possible for a flatpak
+    to request a socket with specific properties from pipewire to mount in the
+    flatpak. The session manager can then assign permissions based on the connection
+    properties.
+  - Support for fixed arrays in pw_array was improved.
+  - Pipewire server and clients can now use multiple threads to process the nodes
+    in parallel.
+  - device.rules and node.rules were added to update device and node properties
+    based on rules.
+  - device.param and node.param can now be used to configure params when devices
+    and nodes are created.
+  - Memory will now try to use MFD_NOEXEC_SEAL.
+  - The driver id of a node is now placed in the properties.
+  - A potential race was fixed when adding and removing ports to the scheduling
+    lists.
+

+  - The RTP sender can now use a timer to send out multiple packets per
+    quantum.
+  - A new module was added for loading Parametric EQ.
+  - The simple-protocol module now has per stream configurable properties
+    and can also be used to interface with a snapcast server.
+  - Support for local services was added to raop, rtp and pulse avahi
+    discoverers. Support for IPv6 on local services was added to RAOP.
+
+## SPA
+  - Support for reporting JSON parsing errors has been added.
+  - Some extra checks are added when iterating POD structures.
+  - Port and profiles can now be hidden from ALSA nodes with
+    api.acp.hidden-ports and api.acp.hidden-profiles properties.
+  - The UCM conflicting devices patches were merged.
+  - Profiles and Routes can now also be set by name.
+  - Hires timestamps are now used when possible in IRQ based scheduling to
+    get more accurate wakup times.
+  - udev can now be an optional dependency.
+  - audioadapter now has an option to automatically configure its ports.
+  - Camera rotation was added to the libcamera node.
+  - invoke on loops can now be done from multiple threads at the same time.
+  - Make sure we use CLOCK_MONOTONIC everywhere in the io_clock.
+  - Vulkan bit and convert filters were added.
+  - ALSA will now always read the HW ringbuffer pointer when followers are
+    not on the same card.

+    a core message pipewire-pulse:describe-module.
+  - An option was added to disable module loading and unloading.
+
+## JACK
+  - OSC messages can now also be placed in JACK MIDI and the translation
+    layer will detect and tag the right PipeWire control message types.
+  - A jack.other-connect-mode was added to limit the connections that an
+    app can do to ports it doesn't own.
+  - The way the transport is started and how the nodes are grouped together
+    in the transport was improved using the new sync groups. (#3850)
+  - Fix large MIDI messages handling. (#4005)
+
+## ALSA
+  - Fix format renegotiation. (#3858)

+  - A new pw-container tool was added to start a new security context and
+    run an application in it.
+  - pw-dot handles properties with quotes better. Nodes are grouped with the
+    node.link-group.
+  - pw-link has a --wait option to wait for all links to be created.
