Thanks to pnlarsson for noting the spelling error in the cli commands. Also, added some verbage about the new algorithm to CHANGES.

* Ability to set process limits ("ulimit") without restarting Asterisk
|
||||
* Enhanced "agi debug" to print the channel name as a prefix to the debug
|
||||
output to make debugging on busy systems much easier.
|

* New CLI commands "dialplan set extenpatternmatching true/false"

|
|||
* Added a new channel driver, chan_unistim. See doc/unistim.txt and
|
||||
configs/unistim.conf.sample for details. This new channel driver allows
|
||||
you to use Nortel i2002, i2004, and i2050 phones with Asterisk.
|
||||
* A new extension pattern matching algorithm, based on a trie, is introduced
|
||||
here, that could noticeably speed up mid-sized to large dialplans.
|
||||
It is NOT used by default, as duplicating the behaviour of the old pattern
|
||||
matcher is still under development. A config file option, in extensions.conf,
|
||||
in the [general] section, called "extenpatternmatchingnew", is by default
|
||||
set to false; setting that to true will force the use of the new algorithm.
|
||||
Also, the cli commands "dialplan set extenpatternmatchingnew true/false" can
|
||||
be used to switch the algorithms at run time.
