Fixed model sub-sampling issues with large objects, including check-image resizing.
Fixed initialization of DETMODEL size guess (thanks to Eli Rykoff).
Fixed image extension pb in double weighting/single image mode.
Improved debug info for memory allocations in FFT and FITS libraries.
Fixed crashes with DETMODEL magnitudes on null measurement weight maps.
Added Eli Rykoff's fix to discard sources with NaNs in the fitted positions.
Improved MKL autoconfiguration.
Improved vectorization in FITS data transformations and FFT-based convolutions.
Pushed SExtractor version number to 3.18.8.

Fixed issues with PSF image extension numbering.
Fixed crashes when calling FFT routines with the MKL library.
Pushed version number to 2.18.2.

Updated FITS library to the latest version, removing potential conflicts with the CFITSIO library.
Added PSF/model-fitting support for MEFs.
Pushed version number to 2.17.0

Fixed triggering of model surface brightness measurement.
Added new FLUX_DETMODEL,FLUXERR_DETMODEL, MAG_DETMODEL,MAGERR_DETMODEL, FLAGS_DE
TMODEL and CHI2_DETMODEL measurement parameters that apply on the measurement im
age a model fitted on the detection image (two PSF models required); these new p
arameters are meant for measuring faint galaxy colors.
Improved displayed info for memory allocation failures.
Increased default maximum number of threads set by configure to 1024.
Updated Copyright display line (2012).
Added support for "TPV" WCS projection.
Pushed version number to 2.16.0.

Added 2nd order moments measurements of the convolved model.
Fixed issues introduced in a recent updates with check-images.
Implemented new algorithms for SPREAD_MODEL and SPREADERR_MODEL (no optimization yet and the scaling is still variable however).
Added experimental SNR_WIN measurement parameter.
Fixed crash with empty ASSOC lists.
Pushed version number to 2.13.6.

Preliminary implementation of a RESCALE_WEIGHTS configuration switch.

Pushed version number to 2.13.1.

Added more complete headers to all files.
Clarified licensing issues.
Updated FITS library.
Updated configuration files.
Added configuration files to the list of data that get installed in ${prefix}/share/sextractor.
Added background offset and point-source model components: FLUX_BACKOFFSET,FLUXERR_BACKOFFSET,FLUX_POINTSOURCE,FLUXERR_POINTSOURCE,MAG_POINTSOURCE,MAGERR_POINTSOURCE.
Tweaked model-fitting convergence parameters.
Fixed catalogue source ordering/number issue in dual-image mode.
Pushed version number to 2.13.0.

Added --disable-model-fitting configure option to turn-off model-fitting features and to allow compiling SExtractor without requiring the ATLAS and FFTW libraries.
Version number pushed to 2.12.0.

Improved real-time display.
Fixed various issues with XSLT in double image mode.
Pushed version number to 2.11.0.
