+
+Commits by bldewolf, feiner.tom, janl, knan, ligne, mha, ssm, steve.schnepp, lupe, jorne
+
+Summary : 
+
+* Huge performance boost
+* munin-graph is over, cgi graphing only from now on
+* Enabling CGI HTML with an reworked UI
+* use a binary DB to store spoolfetch timestamps (fixes growing file bug in 2.0a1)
+* documentation cleanup
+
+Enhancements : 
+
+* Better node side timeout error message allowing things to be found out if needed
+* Properly label the bgbouncer queries-per-second graph.
+* Properly return undef when the SNMP client returns noSuchObject instead of setting an error.
+* munin-node: Insert a reset_timeout() call to enable the master to get in a word in edgeways after a slow plugin has executed
+* munin-html: Start using fork to save some wall-clock time.  Option --fork us now active and max_html_jobs is recognized by munin-html as the maximum number of paralell processes.
+* Actually recognize max_html_jobs as a config parameter
+* Add the publication part
+* Clean up Perl warnings due to use of undefined variables in two functions in LimitsOld.pm.
+* looking at the Net::SNMP doco, -username cannot be '' (it must be between 1 and 32 characters).
+* The time of munin-graph is over, cgi from now on
+* since pollers are now being respawned if they fall over, the shutdown-spooler signal handlers need to be removed before starting any poller up.
+* Cleanup of munin-cgi-graph:
+  - Make it log right
+  - Make it fast (now <0.1s pr graph on reasonable hardware)
+  - Remove $config deep copy, it is too expensive, we need to fix
+    expand_specials instead.
+  - BUG: Broke --pinpoint processing
+* Munin::Master::Utils:
+  - Replace some often used REs with string matches for speed.  Helped
+    speed up munin-cgi-graph quite a bit.  Introduced munin_dumpconfig
+    to help debug the expand_specials issue
+  - Introduce munin_find_node_by_fqn to do faster lookups of things
+    to graph.
+* Munin::Master::GraphOld:
+  - Restructure a bit to avoid double loading of $config (in
+    cooperation with munin-cgi-graph) and make it possible to pass
+    some graphing options (--only-fqn for example) in some new places.
+  - Propper logging the right way
+  - NOTE: All code relating to host and service filtering and looping
+    should be removed soonish - we're only using the FQN to find our
+    work now.
+* Replacing 'echo -n', which is implementation-defined - with printf, which is posix
+* munin-update: Add local URI scheme to enable running async collector directly on the master as this may somehow enable push-to master. Closes #981, thanks to jorne
+* ALWAYS dumps the RRD cmd used when an error occurs when RRD::graphing
+* Add some extra HTTP Response Headers
+* JMX refactoring by Joachim Sauer
+* add some external tools to ease a Storable datafile
+* Enabled multigraph capabilities for the munin-async-server
+* Re-work filtering in linux df plugin to be much more flexible.
+* Force lpstat to C locale instead of EN_us.
+
