+## Fix Wforce complaint about not being able to create temporary files on startup
+
+Wforce 2.6.x uses an HTTP library which creates temporary directories for file upload on startup, 
+by default in the current working directory, which for wforce is the config directory. For packaged
+installation of wforce, this is /etc/wforce, which is typically not writable by wforce itself, leading
+to errors. This fix changes the directory for those temporary files to /tmp/wforce.
+
+## Fix timing issue with webserver and syncDB
+
+In rare cases when starting up, the syncDB command may start, replicate from another wdforce instance, 
+and complete, before the webserver had finished initializing. This would cause the syncDone command from
+the other wforce instance to fail. This fix forces wforce to wait until the webserver is ready before
+starting the syncDB checks.
+
+## Fix issue in wforce docker image where the default config file was overriden by a volume mount by not used
+
+The wforce docker image documentation states that a volume mount can be used to specify a custom config file
+in /etc/wforce/wforce.conf, however this was not actually the case. The file was only used if the environment
+variable WFORCE_CONFIG_FILE was also set, which is incorrect, because that variable is only supposed to be used
+to specify a *new* location for the config file. This fix ensures that whenever a volume mount correctly
+mounts a custom /etc/wforce/wforce.conf file, it is both used, and a log message is output stating that it
+is being used.
