Fixed issue with magnitudes when used as PSF model parameters (thanks to A.Donnarumma for reporting this issue).
Added ID_PARENT catalog parameter to identify the common parent of deblended sources (thanks to R.McMahon for the suggestion).
Introduced regularization of Sersic model ellipticities based on AMALGAm prescriptions for the Great3 challenge (see Mandelbaum et al. 2015).
Fixed error in ecliptic coordinate computations (thanks to H.Bouy for reporting this issue).
Added support for differential geometry maps, with new DGEO_TYPE and DGEO_IMAGE configuration keywords and new DGEOX/Y_IMAGE and DGEOX/YWIN_IMAGE measurement parameters.
Added differential geometry map correction to model-fitting.
Added VIGNET_DGEOX and VIGNET_DGEOY differential geometry map cutouts in catalogs (for use in PSFEx).
Added support for PSF model dependencies in ASSOC vectors.
Fixed issue with single-line background meshes.
Fixed positional offsets of large galaxy models on MODELS and -MODELS check-images.
Pushed version number to 2.23.1.

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.

Added new ASSOCCOORD_TYPE configuration parameter for ASSOCiating detections either in PIXEL or WORLD coordinates.
Fixed sampling issues for Sersic, de Vaucouleurs and exponential model-fitting.
Version number pushed to 2.13.2.

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.

Fixed X/YMODEL_WORLD issue.
Increased CLEANing margin for model-fitting.

Fixed several issues related to image and weight copy prior to fitting.
Fixed bug with symmetric models.
Fixed issue with new FFT planning scheme.
Pushed version number to 2.9.5.
