 libraw1394 Release Notes
 
+Version 2.1.0:
+- Behavior changes of the backend to firewire-core:
+    - The isochronous reception buffer is now mapped read/writable
+      rather than read-only.  The raw1394 backend already maps the
+      buffer read/writable too.  Note that writing into the buffer
+      will go wrong on architectures without cache-coherent DMA if
+      the CPU and the OHCI write within the same cacheline region,
+      so use this feature with caution.
+    - Decrease memory footprint of IR and IT buffers by avoiding
+      some internal rounding up of the buffer size.
+- New APIs in <libraw1394/raw1394.h>:
+    - raw1394_add_config_rom_descriptor():
+      Add contents to the Configuration ROM of the local node(s).
+      At runtime, this API is only available if running on top of
+      firewire-core.  It could probably also be implemented with
+      the raw1394 kernel driver if anybody cared.
+    - raw1394_remove_config_rom_descriptor():
+      Counterpart to raw1394_add_config_rom_descriptor().
+    - raw1394_read_cycle_timer_and_clock():
+      Like the existing raw1394_read_cycle_timer(), but lets the
+      caller choose between CLOCK_REALTIME (which the former call
+      is always using), CLOCK_MONOTONIC, or CLOCK_MONOTONIC_RAW.
+      For example, this enables libffado's audio streaming to run
+      undisturbed by resets of CLOCK_REALTIME.
+      At runtime, this call requires firewire-core underneath.
+    - raw1394_get_speed():
+      Returns the speed code of the maximum possible transmission
+      speed between a given node and the local node.  This takes
+      maximum speeds of all participating PHYs and the two links
+      into account.  This can be used to configure the speed of
+      isochronous streams.
+      At runtime, this call requires firewire-core underneath.
+    - enum raw1394_iso_speed was extended by
+      RAW1394_ISO_SPEED_800, _1600, and _3200.
+- New APIs in <libraw1394/ieee1394.h>:
+    - Added preprocessor constants
+      L1394_SPEED_BETA, L1394_SPEED_800, _1600, and _3200.
+- testlibraw1394:
+  Added unit tests of the new APIs.
+
 Version 2.0.9:
 - Fix that raw1394_iso_recv_flush() did not have any effect when running
   on firewire-core alias juju kernel drivers.  Requires kernel 3.4 or
