2.5.0 is a feature release and builds against kernels from 2.6.9 up to
and including 3.0. Some of the more notable changes from the 2.4.0
release are:

General DAHDI Changes:

* Software and Hardware (if available) echo cancellation can be mixed on a
  line if desired. This also allows hardware echo cancellation to be disabled
  without reloading the drivers.

* Channels can be configured to generate channel events when there are
  data under runs or over runs. Can be used when tracking down the source of
  data skips. 

* Debug flag can be set to show RBS bit changes in kernel log.

* Much refactoring in in dahdi-base to enable tighter integration with udev /
  sysfs in upcoming releases.

Updated Drivers:

* wctdm24xxp, wcte12xp: Added support for VPMOCT032 hardware echo
  cancellation module.

* wctdm24xxp: Fix regression with forward disconnect.

* wctdm24xxp, wcte12xp: Decrease the amount of time spent in the interrupt
  handler.

* wctdm24xxp: Added fastpickup module parameter to help with type-II caller id
  detection.

* wcte12xp: Properly recognizes loopup / loopdown signals.

* wct4xxp: Reduced kernel memory footprint and stack usage.

* wct4xxp: Added module parameter to allow the rotary switch settings to be
  ignored at module load time.

* wcb4xxp: Support for beroNet BN4S0e PCI Express card.

* xpp: support for a hardware echo canceller.                                                                                                                         
  Requires "octasic" support in dahdi-tools (as of 2.5) and the                                                                                                       
  firmware from http://updates.xorcom.com/astribank/hwec/                                                                                                             

* xpd_fxs - added parameter ring_trapez for a trapezoid (stronger) ring.         

Changes to DAHDI-tools:

* xpp: low-level USB tools can now use a relative -D mmm/nnn instead of
  a full -D /dev/bus/usb/mmm/nnn .

* xpp: Octasic support: oct612x code included to allow loading the
  Astribank hardware echo canceller module's firmware.

* xpp: xpp_order doesn't work when more then 9 ABs are listed
  (xpp/perl_modules/Dahdi/Xpp.pm)
