o Minor bugfixes (directory permissions):
- When a user requests a group-readable DataDirectory, give it to
them. Previously, when the DataDirectory and the CacheDirectory
were the same, the default setting (0) for
CacheDirectoryGroupReadable would always override the setting for
DataDirectoryGroupReadable. Fixes bug 26913; bugfix on
0.3.3.1-alpha.
