+
+### Added
+- Added a few tweaks to improve drawing performance:
+  - Improved color type conversion performance by using compiler specific byte swap functions.
+  - :rocket: **Greatly** improved image drawing performance by performing color type conversion only once, instead of letting Skia handle it automatically on every draw operation.
+  - :rocket: **Greatly** improved drawing performance for fully opaque images, by skipping alpha channel conversion on draw. Drawing JPEGs and opaque PNGs got over 10 times faster on some tested devices.
+  - Improved text drawing performance by caching font objects and avoiding unnecessary font loading.
+
+### Changed
+- Force usage of software graphics on Linux/ARM systems until we find a proper way to detect support for hardware accelerated graphics - #259
+
+### Fixed
+- Class java.util.Objects would sometimes be not available on the device.
+- Segfault during SDL initialization reported in some systems - #263, #265
+- Fixed screen not updating on some devices, by refreshing the SDL_Surface on repaint.
+- XmlTokenizer was still trying to use the old byte implementation when running on device.
