## Security Changes Only

Except for security changes, no further maintenance will be applied to this branch.
You are encouraged to upgrade to a maintained branch as soon as possible.
Maintained branches are master (preferred - version is 5.0.0 as of the date when this is being written), release390 (current version is 3.10.0), and release222 (2.4.0).
