Release Name: 2.3

Notes:
This minor release adds an in-memory map cache
to speed up pan and rotate operations.  The cache
is dynamically sized and the maximum size adjusts
based on whether or not Maemo Mapper receives a
"low memory" message from Maemo.  The max size
can only decrease, so if you open a lot of
applications and Maemo Mapper reduces the size of
the cache to compensate, then you must restart
Maemo Mapper in order to restore the original
cache size.


Changes:
  * Added an in-memory map cache to improve pan performance (thanks to Tim
    Terriberry for the patch).
  * Fixed bug with infinitely repeating auto-route-update error messages.
  * Added option to completely disable all announcements.
