@ -23,6 +23,12 @@ Noteworthy changes in version 2.1.x (under development)
* Support for Windows CE.
* If the agent's --use-standard-socket option is active, all tools
try to start and daemonize the agent on the fly. In the past this
was only supported on W32; on non-W32 systems the new configure
option --use-standard-socket may now be used to use this feature by
default.
Noteworthy changes in version 2.0.13 (2009-09-04)
