SDK 1.10.11 Release

A happy new year to all! We’d like to kick this year off with a fresh new release of Panda3D. This is another maintenance release containing bug fixes and minor improvements. A full list of changes is included below.

Since the new release is not expected to contain regressions or backward-incompatible changes, it is a recommended upgrade for all users on lower releases. Head to the download page to get the latest binaries and source code.
