This release replaces the libJASPER JPEG2000 codec backend with OpenJPEG. Furthermore, the CMake has been modernized to use target_* directives more broadly. Last, this is the first version which has Ubuntu (and derivatives) 18.04 support.

Note: this is the last main version where we support 16.04, 18.04 is our new LTS. There is now no longer an explicit dependency on libopenslide in the 16.04 version as the package repositories only contain 3.4.0 and not the 3.4.1 with support for Philips TIFF. So if you want support for openslide formats I highly recommend installing version 3.4.1 manually, or, if you do not need support for Philips TIFF, install the 3.4.0 package from the repositories.

All releases now use Python 3.6, so this identifier is dropped from the filename.

Release contains mostly bug fixes for loading the rectangle annotations. One new feature is support for reading and writing sparse TIFFs (TIFF files that do not have all tiles written).

New features in this release:

• Support for rectangle annotations. Double-click to specify width and height exactly
• Support for unicode TIFFs. Windows binaries include OpenSlide version which supports unicode paths on Windows.
• Custom annotation colors are now persistent
• Separated functionality of ASAP into ASAPLib for easier linking on other platforms

This is the last release for Ubuntu (and derivatives) 16.04, the next release will be on the new LTS 18.04.

This release contains a big modification to loading of whole-slide files. In ASAP you can now specifically indicate which backend to use for loading the file. By default ASAP tries to identify the best one. Furthermore, it includes a bug fix for dot annotations which could cause a crash on removal.

This release contains a fix for multi-resolution TIFF with tiles stored in the yCbCr color space (example in the generic TIFF test data of OpenSlide). I also added a release linked against Python 3.5 and one against 2.7. From next release on we will switch to Python3 for the provided builds.
