Both of these are fixed in the current matplotlib release. You may
want to consider upgrading, particularly if you are actively writing
date code, since the date handling has changed and it may be less
painful to upgrade sooner rather than later when you have a large code
base installed. See the release notes at what's new for matplotlib
0.63.

Also, *many* memory leaks have been fixed - for web applications, this
may be important.
