  * Major internal restructuring
  * New formats: Hamamatsu NDPI, Sakura SVSLIDE, Ventana BIF (preliminary)
  * Add openslide_detect_vendor()
  * Deprecate openslide_can_open() (not very useful and often misused)
  * Document performance considerations for openslide_open()
  * Add properties giving the bounds of the non-empty region of the slide
  * leica: Support multiple main images if their levels are coplanar
  * leica: Use slide size as level size

  * Fix some crashes in error paths
  * Add tests for many error paths

- Update to version 3.3.3
  * Properly handle Aperio JP2K slides with zero-length tiles
  * Support Hamamatsu slides with blank MacroImage key

- Update to version 3.3.2
  * Fix seams in MIRAX 2.2 slides
  * Fix associated image naming in single-level Aperio slides
  * Stop decoding MIRAX tiles outside requested region
  * Stop decoding unneeded tiles during tile-aligned accesses
  * Increase Hamamatsu VMU tile size to reduce rendering overhead
  * Document performance considerations for openslide_can_open()

- Update to version 3.3.1
  * Parallelize concurrent openslide_read_region calls on an openslide_t
  * Eliminate background scanning of tile headers in MIRAX
  * Scan many fewer tiles during first accesses to Hamamatsu VMS
  * Ignore Leica Z-planes other than 0
  * Add experimental tile-size properties
  * Document API thread safety

- Update to version 3.3.0
  * Support Leica SCN format (requires libtiff >= 4) (thanks, Agelos Pappas)
  * Allow opening MIRAX 2.2 slides (though there are seams, bug #92)
  * Add standardized microns-per-pixel and objective-power properties
  * Add "macro" associated image in Trestle
  * Rename "layer" to "level" throughout the API (deprecate "layer" functions;
    remove "layer" properties)
  * Report parse errors in openslide_open() by returning an openslide_t in
    error state
  * Deprecate openslide_get_comment()
  * Add openslide_get_version()
  * Improve command-line tools; add manpages
  * Support building with MinGW-w64; drop CMake, MSVC, mingw32
