0.7 pre-release

(Note: odd-numbered version are test releases. This release is intended as a test and will become version 0.8 once released)

Changes since 0.6.1:

New features:

• Support for .head text files to override fits file headers
• New option --dump-default-config to produce a default configuration file
• Added --grouping-moffat-max-distance option to constrain Moffat grouping to a maximum distance in pixels
• Added an optional sliding window for Lutz segmentation (--segmentation-lutz-window-size), this allows measurement to start on sources that fall outside the window to save on memory and enable multithreading sooner. Off by default.
• Support for the GSL minimization engine as an alternative to levmar. Levmar is still the default and recommended.
• New signal to noise ratio check image (--check-image-snr)
• New core threshold cleaning method (--partition-corethreshold)

Bug fixes and minor changes:

• Fixed crash when Moffat model fitting starts with a negative value as flux guess
• Added grouping options into the help display
• Removed "sextractor" name from the code
• Fixed a crash when exiting if using external plugins
• Improved the robustness of multi-extension FITS loading
• Improved performance of Moffat model evaluation
• Will look for plugins in default directories too
• Fixed pixels with negative variance values sometimes appearing
• Compressed FITS files are now loaded correctly
• Improved error reporting from Python
• Outputs more and better background modelling statistics
• Fixed compilation issues on OSX
• Better multithreading performance if levmar was compiled with the proper options to be fully reentrant
• Made the code compatible with the Intel compiler
• Fixed default configuration file not found warnings
• Source ids now start at 1 instead of 0 (source 0 was previously not distinguishable from the background on the check images)
• The output catalog is now written incrementally instead of all at once (controllable with --output-flush-size)
