Release of Bio-Formats 5.2.3

The OME Consortium are pleased to announce the release of Bio-Formats 5.2.3

Dear All,

Today we are releasing Bio-Formats 5.2.3, a bug-fix release.

Improvements include fixes for three formats:

  • CZI
    • fixed imageCount for RGB images
  • ICS writing
    • fixed ordering of image dimensions
  • DeltaVision
    • fixed reading of large time dimensions

Other improvements:

  • Command-line tools
    • now includes the version history as NEWS.rst (thanks to Gerhard Burger)
  • Code clean-up
    • switched to String.indexOf(int) in GPL-licensed reader code so that a simpler library method can be used
    • strings now extended with characters where possible
    • completed deprecation of DataTools.sanitizeDouble()
    • deprecated unused OSGi and ome-tools bundle build targets
  • Documentation
    • documented versioning policy
    • clarified supported versions for Micro-Manager and Olympus ScanR files
  • OME-XML changes
    • bumped schema version number to 2 (schema namespace left unchanged)
    • added acquisition modes BrightField, SweptFieldConfocal and SPIM
    • added parsing for Laser Scan Confocal and Swept Field Confocal
