## Notes for end users
### Automatically switch Bluetooth profile when using VoIP applications
Bluetooth headsets typically support both the A2DP profile, which is
suitable for music, and the HSP profile, which is suitable for
telephony use cases. module-bluetooth-policy will now automatically
switch the profile of a Bluetooth headset from A2DP to HSP/HFP when an
application creates a recording stream with property media.role=phone
(telephony applications should set that property for their
streams). When the stream goes away, the profile gets restored back to
A2DP. This way the user doesn't have to manually switch the profiles
when starting and stopping a call. This behaviour can be disabled by
giving argument auto_switch=false to module-bluetooth-policy.
### New module for prioritizing passthrough streams (module-allow-passthrough)
Passthrough streams are streams whose content must go completely unaltered from the application to the sound card, and they are mainly used for playing back compressed audio through an S/PDIF connection. When a passthrough stream is playing to a device, no other streams can play at the same time to the same device, and if there's already something playing when a passthrough stream is created, the passthrough stream creation will normally fail. Now we have a new module, called module-allow-passthrough, which will give higher priority to passthrough streams, so that if there are other streams playing when a passthrough stream is created, those other streams will be moved out of the way to a dummy device.
### Fixed hotplugging support for USB surround sound cards
A long-standing bug that prevented PulseAudio from using any
hotplugged USB surround sound cards has been fixed.
### Separate volumes for Bluetooth A2DP and HSP profiles
The Bluetooth sink and source names are now different depending on
whether the active profile is A2DP or HSP. This allows PulseAudio to
store different volumes for A2DP and HSP. Due to different mechanisms
for implementing volume control between the profiles, trying to use
the same volume value in PulseAudio doesn't actually result in the
same perceived volume, so it's better not to try to use the same
volume.
As an unfortunate transition effect, volumes saved earlier with an
older PulseAudio version won't have effect in the new PulseAudio
version, so all Bluetooth devices will have their volume reset to the
default value when running the new PulseAudio version for the first
time.
This only affects BlueZ 5 users. The same change was done already
earlier for PulseAudio's BlueZ 4 code.
### memfd-based shared memory mechanism enabled by default
The memfd-based shared memory mechanism that was implemented in 9.0 is
now enabled by default. This shouldn't cause any user-visible changes
in behaviour, except if you're using the Firejail sandboxing software,
which doesn't work with PulseAudio's old shared memory mechanism.
If desired, the feature can still be disabled by setting "enable-memfd
= no" either in daemon.conf (for disabling it at the server side) or
in client.conf (for disabling it at the client side).
### Removed module-xenpv-sink
module-xenpv-sink was removed, because it's probably not used by
anyone. If you use it, please let us know.
## Notes for packagers
### Dropped dependency to json-c
libpulse previously used json-c internally, which forced applications
to link to json-c too. That caused crashing in some GLib applications,
because json-c and json-glib both use the same name for some
functions. To solve this, we implemented the necessary JSON
functionality directly in libpulse, so we don't depend on json-c any
more.
### When using systemd to start PulseAudio, pulseaudio.socket is always started first
The pulseaudio.service unit now depends on pulseaudio.socket, meaning
that before systemd starts PulseAudio, it will always first set up the
socket. This is done to avoid confusing behaviour in certain corner
cases (see the comments in pulseaudio.service for a more detailed
explanation).
### Compatibility with OpenSSL 1.1.0
OpenSSL, which is used by module-raop-sink, broke backwards
compatibility in the 1.1.0 release. PulseAudio now supports both 1.1.0
and older versions.
### Clarified qpaeq license
Most of PulseAudio is licensed under LGPL, but the "qpaeq" equalizer
GUI is licensed under AGPL. That hasn't previously been mentioned
anywhere else than in the qpaeq source code itself. Therefore,
distributions that tag their packages with license information have
likely used incorrect information. The license of qpaeq hasn't
changed, but the use of AGPL is now correctly noted in the top-level
LICENSE file.

Changelog:
Since we had a couple of annoying bugs in 7.0, we thought it'd be a
good idea to do a 7.1 to address those.

systemd socket activation support
Better support for multichannel and 2.1 profiles
Remap optimisations
Many minor improvements, bug fixes, and i18n updates
Notes for Application Developers
New function in libpulse: pa_stream_write_ext_free(). The function allows more flexible use of free callbacks than the regular pa_stream_write() function. This is useful if an audio buffer is part of a bigger structure that needs to be freed or unreferenced when the audio buffer is no longer needed.
We now have Vala bindings for libpulse-simple.
on Linux. What were they thinking... If there is one platform that it's
rash to make assumptions about API consistency on, it's Linux...
Fixes build on Ubuntu 11.10.
* Remove dependency to sysutils/hal, hald backend is removed.

PulseAudio 3.0 Release Notes
We're, back with another shiny PulseAudio release! While the 3.0 release was a little delayed, it brings a number of important improvements, and bug fixes. A summary of changes follows.
Notable Changes
ALSA Use Case Manager (UCM) support
Runtime editable LADSPA filter parameters
Out-of-the-box support for Bluetooth sources
ARM NEON optimisations
Configurable device latency offset
Adhere to the XDG Base Directory Specification
Various ALSA changes
Lots of infrastructure improvements
Packaging
Bluetooth support requires now "sbc", a library for the SBC codec. The codec used to be included within PulseAudio, but it has now been split off into a separate library. It's available at http://www.bluez.org.
Support for the "socket API" of BlueZ has been dropped in favour of the D-Bus based "media API". Due to this change, the minimum supported version of BlueZ is now 4.99. Also, make sure that you don't have "Disable=Media" in /etc/bluetooth/audio.conf. And due to a bug in BlueZ, it's probably necessary to have "Disable=Socket", otherwise there will be problems with the A2DP profile.
Support for HAL has been removed. This shouldn't affect anyone, but if it does, please configure PulseAudio to use udev instead. module-hal-detect still exists for maintaining configuration file compatibility, but all it does is to load module-udev-detect. module-hal-detect may get completely removed in 4.0.
* Tested on NetBSD/i386 5.1, /i386 6.0, and /amd64 6.99.13
* Also tested on OpenIndiana/i386 151a7, but my environment lacks audio
device, so I cannot check audio output
* Tested with multimedia/mplayer's -ao pulse option, works fine
* Add gm4 to USE_TOOLS for OpenIndiana build
Changelog:
Many changes. See http://www.freedesktop.org/wiki/Software/PulseAudio .
Also add a patch by drochner:
pthread_key_create returns 0 on success; return values on failure are
not defined.
Remaining patches without comments:
patch-ab: adding an ifdef notyet in src/daemon/main.c
patch-a{c,e}: --start -> -D (no idea why)
patch-af: allow some Linux-only code also on NetBSD
patch-ah (new):
Fix wrong placed #else clause against #if defined(__linux__) in cpu-arm.c.
patch-ba:
Check NetBSD's native atomic_ops in configure even in arm case.
configure checks $host_cpu first, not $host_os on checks for
native atomic operations.
(In upstream it seems fixed to see $host_os first but
it might still have problem around NetBSD version checks)
