There are lots of enhancements, in fact, although none (almost) of the "spectacular things" that I had planned. Just out of my (poor) memory:
- First 64-bit version for Mac OS X. It is 100% production stable although still tagged as "experimental" due to some graphical glitches.
- First 32-bit and 64-bit versions for FreeBSD/X11. Although they won't be available in the initial release, they will be published during August-September. These will be Tier-1 releases, comparable in all respects to the reference Linux/X11 versions.
- StarAlignment: Selectable/automatic interpolation algorithm (including all the algorithms available in Resample, for example), improved frame adaptation feature, improved console information output.
- ImageIntegration: New persistent file cache, new Linear Fit Clipping rejection algorithm.
- ImageCalibration: New DefectMap tool.
- PCL: A completely new interface between modules and the Core application. Now compatibility of existing modules is guaranteed for all future PI and PCL releases.
- PCL: Important changes in PCL's multithreading infrastructure (this improves performance of all processes and the core application).
- Color management: Integration of LCMS version 2 (more accurate and faster color calibration). All the color management functionality is now provided by the Core application (previously all modules had to be linked against LCMS).
- GUI: Refactored ProcessExplorer. Now all featured scripts are accessible from the ProcessExplorer window, so they can be added to favorites, for example.
- FITS support: Added an option to correctly interpret signed FITS images storing physical pixel values.
and many things that I must review my notes to recall.
There are literally hundreds of bug fixes. This version aims to be extremely stable on all platforms. Although many changes are not visible on the surface, it builds the foundations to a new major release which will include important new features.
