Reverted minimization algorithm back to double precision (while keeping single precision for data and parameters in "bounded" space).
Added specific handling of "Jacobian calls" in model-fitting.
Sped up the resampling process in model-fitting.
Tuned up minimization algorithm in model-fitting.
Added shortcuts to the computation of the local PSF model. 
Fixed triggering issues with some model-fitting parameters (thanks to S.Serrano).
Removed CLASS_STAR_MODEL and DISK_PATTERN* measurement parameters.
Added automatic tracking of the PSF FWHM from the local PSF model if SEEING_FWHM is 0 for CLASS_STAR.
Fixed excessive WIN parameter computation time on large ring-shaped objects.
Fixed model-fitting issue with null half-light radii (thanks to S.Desai and B.Armstrong).
Fixed aperture display value error in FITS-LDAC catalogue header.
Removed redundant update_tab() calls in FITS library.
Fixed comment copy issue for slashes within strings in FITS library (thanks to F.Schuller).
Added check of PSF values; SExtractor will now exit in error in the case where all PSF components sum up to 0.
Replaced computation of model second moments and ellipticities with analytical estimates.
Improved the accuracy of peak and average model surface brightness estimates.
Fixed some compiler warnings.
Pushed version number to 2.11.7.

Fixed various compilation warnings.

Added support for 64 bit binary table elements in FITS library (thanks to J.P. McFarland).

Changed configure behaviour towards CFLAGS and LDFLAGS: automatic settings are now applied only if the --enable-automatic-flags configure option is set (thanks to S.Pascual).
Version number pushed to 2.9.0.

Replaced configuration error with warning if FFTW is not multithreaded and multithreading has been activated (unused).
Added autoconfig support for FFTW multithreaded versions combined in libfftw3 (unused).
Added runtime warning if ATLAS is not multithreaded and multithreading is on (unused).
Version number pushed to 2.8.8.

(thanks to D.G. Bonfield for the suggestion).

Cleaned up Makefile.am RPM options.
Fixed rpm build issue on Fedora Core 10.
Fixed display of max thread number in configure help.
Updated icc compilation flags to 11.0 syntax.
Set the license string to CeCILL in the .spec file.
Pushed version number to 2.8.5.
