A quick summary of recent significant DevStack changes:

* Keystone Service Catalog SQL back-end
Add "KEYSTONE_CATALOG_BACKEND=sql" to localrc to tell Keystone to use
the SQL backend for the service catalog.  This enables the keystone
service-* and endpoint-* commands to manage the service catalog. See
files/keystone_data.sh for the default commands used by DevStack.
DevStack continues to use the templated service catalog by default.


* Remove default services from ENABLED_SERVICES
This change allows easy the removal of services that are in
ENABLED_SERVICES by default (see the list in stackrc) by appending the
service name prefixed with a '-' to ENABLED_SERVICES.  For example, to
switch from Nova Volumes to Cinder, you would add this to localrc:

ENABLED_SERVICES+=,-n-vol,c-api,c-sch,c-vol

(Note the leading comma following the equals sign)


* Cinder Support
Speaking of Cinder, basic support was merged last week.  Since it is
still a bit of a moving target additional updates may still be
required.  Enable Cinder as shown in the ENABLED_SERVICES section
above.  Nova Volume will remain DevStack's default until some time
after Cinder becomes the default in Nova.
  * The default volume group name has changed to stack-volumes to
remove the nova project name (it was formerly nova-volumes).  Set it
in localrc with VOLUME_GROUP.
  * The default backing file is now
/opt/stack/data/stack-volumes-backing-file (it was formerly
/opt/stack/nova-volumes-backing-file).  Set it in localrc with
VOLUME_NAME_PREFIX.


* Colored logs
Vish added color to Nova's logs a couple of weeks ago to greatly help
visually scanning the log files.  Set "LOG_COLOR=False" in localrc to
disable the color as it is enabled by default.  Also note that if
SYSLOG=true the log coloring is also disabled.
