* Various extensions to Local Minima and Maxima (3D algorithms, on-the-fly
thresholding).
* Added vigra::BucketQueue, vigra::MappedBucketQueue.
* Refactored and extended 2D watershed algorithms (especially
watershedsRegionGrowing()).
* Added the vigra::Quaternion class.
* Added Unsupervised Decomposition.
* Added mathematical functions (even(), odd(), gamma(), loggamma(), legendre(),
besselJ(), besselY(), linearSequence(), indexSort(), inversePermutation(),
applyPermutation(), checksum())
* Implemented wrapper of the FFTW library to support arbitrary dimensional
Fourier transforms (see fourierTransform() and vigra::FFTWPlan) and FFT-based
convolution (see convolveFFT() and vigra::FFTWConvolvePlan) and refactored
vigra::FFTWComplex.
* Added cannyEdgelListThreshold(), cannyEdgelList3x3Threshold().
* Added capability to handle subarrays and anisotropic resolution to
separableConvolveMultiArray() and related Gaussian filters. Added windowRatio
parameters to vigra::Kernel1D::initGaussian() and
vigra::Kernel1D::initGaussianDerivative()
* Added vigra::StridedScanOrderIterator and corresponding
vigra::MultiArrayView::begin().
* Extended vigra::MultiArrayView. Added vigra::Shape1 ... vigra::Shape5
convenience typedefs.
* Implemented vigra::multi_math (arithmetic and algebraic functions for
multi-dimensional arrays).
* Extended the vigra::HDF5File class.
* Improved and documented the Timing macros for runtime measurements.
* Added support for the OpenEXR image format and multi-page TIFF. Improved
support for the SIF format.
* vigranumpy: added axistags and completly re-implemented VigraArray and the
conversion between Python and C++ arrays in terms of axistags.
* Minor improvements and bug fixes in the code and documentation.
* Removed the call to png_read_transform_info() when the system libpng
is being used, so it can be built with a system libpng.
Changes 1.7.19:
* pngcrush-1.7.18 failed to read interlaced PNGs. Reverted the change
from calling png_read_transform_info() to png_read_update_info().
Since png_read_transform_info() is not exported we again cannot build
with the system libpng15.
Changes 1.7.18:
* This version will work with either a "system" libpng14 or libpng15, or with
the embedded libpng15. The deprecated usage of libpng png_struct members
and unexported functions has been removed.
* Revised the format of the time report (all on one line so you can get
a nice compact report by piping the output to "grep coding").
* Exiv2 utility
- Fixed time setting of -T option when DST is in effect.
- Added version hex number to the output of "exiv2 -V".
* Exiv2 library
- Exif version 2.3 missing tag codes.
- Tamron 18-270mm lens.
- Exif 2.3 & DNG 1.2/1.3 tags.
- Some tests depend on system settings (locale, path, etc).
- Sort iptc data by record number when encoding.
- New Tamron 70-300 mm lens improperly recognized.
- "Assertion `sv == d' failed" in 0.21.1 (r2474).
- Build failure on MinGW with GCC >= 4.6 because of "-no-undefined".
- Debug messages of psdimages.cpp go to stdout instead of stderr.
- PSD resource block handling patch II.
- Setting metadata on an image should always succeed.
- Exiv2 fails to write to JPEG with an empty APP13 Photoshop PS3 segment.
- Wrong ELSE statement in src/CMakeLists.txt.
- On Windows (MSVC and MinGW builds), charset conversions now use respective
Windows functions if iconv is not available.
- Support for Encapsulated PostScript (*.eps) files.
- The exiv2 library should be re-entrant.
- Fixed typo: SupplementalCategory -> SupplementalCategories.
- Added Tokina AT-X 107 AF DX Fish-eye 10-17mm f/3.5-4.5 lens.

Changelog:
2011.10.01 v.11.10
+ New function: classic gamma curve edit for brightness and individual
RGB colors. Applicable to the whole image or a selected object/area.
+ Printing was revised to work better with recent changes in HPLIP that
made printing on small paper sizes more difficult. The paper size must
be specified in the Printer Properties dialog (printer admin function)
and not in the application program - otherwise the print fails with a
"paper mismatch" error. This changed between Ubuntu 10.10 and 11.04.
+ New function: convert "tetragon" image into a rectangle. Useful for
gallery paintings photographed from the side to avoid reflections,
buildings photographed at an angle, etc.
+ At startup, check for new files, advise if synchronization is needed.
+ New option: warn if overwriting original (non-versioned) image file.
+ Slide Show: stop strange behavior when multiple monitors are used.
+ Slide Show: option to show only the most recent version of each image.
+ Slide Show: use spacebar to pause and resume slide show.
+ Pixel Edit: transparency adjustment steps were made finer.
+ Code cleanup for new compiler warnings from GCC 4.6 (Ubuntu 11.10).
2011.09.26 v.11.09.1
+ Bufgix: crash in Slide Show if the last transition type (jaws) is
not included in the user preferences.
2011.09.01 v.11.09
+ Print Image File now has margin inputs and tiny margins also work.
+ The Portuguese translation was brought up to date.
+ Minor source code changes were made for better BSD compatibility.
+ Show RGB: labels on monitored image points were made optional.
+ Gallery: larger font for file names is used when thumbnails are large.
+ Edit Captions and Edit User Comments were combined into one function.
+ File Open will discard a preceding search result or named collection,
and the user is notified and may proceed or cancel.
+ File > Open (menu and toolbar) can now be used to open a single RAW
file (as tiff-16). A batch conversion function is also available.
+ CPU load monitor on status bar now includes spawned subprocesses.
+ Smart Erase: improved algorithm gives better results in some cases.
+ Panorama: image overlap requirement was relaxed.
+ Bugfix: Flatten: fix uneven conversion of pixels with max. brightness.
+ Bugfix: crash if Tools > Add Menu is started and then canceled.
+ Bugfix: minor memory leak.
2011.08.01 v.11.08
+ An Italian user guide has been added.
+ New function DRGB: change brightness and color balance using OD units.
+ Revise_RGB: added delta mode (show +/- changes from original image).
+ Show RGB: added EV and OD units, delta mode, and pixel labels on image.
+ Slide Show: two image transitions were added, "radar" and "jaws".
+ Slide Show: preferred transition modes can be selected and remembered.
+ Delete Area was renamed to Unselect Area (to reduce ambiguity).
+ F1 help topic is now determined by the last dialog opened OR USED.
+ Bugfix: disable a select-area if Undo/Redo changes the image size.
+ Bugfix: Create Blank Image got leftover EXIF data from a prior image.
+ Bugfix: buffer overflow crash in Russian locale. Several other risky
places from long translation strings were identified and fixed.
+ Bug workaround: crash from GCC 4.5 optimization removing necessary
code. Do-nothing variable references were added to prevent this.
+ Annoyance fix: rapid repetition of prev/next buttons or arrow keys
was sometimes causing a "function still active" popup message.
+ Current bug: On Ubuntu 11.04 Fotoxx refuses to print with small paper
formats (A5, A6). Ubuntu 10.10 works OK. I cannot fix this.
* Changed "#if !defined(PNG_NO_STDIO)" to "#ifdef PNG_STDIO_SUPPORTED"
as recommended in the libpng documentation.
* Added PNG_UINT_32_NAME macro and used it to simplify chunk_type integer
definitions.
Changelog:
Gource 0.37 has been released, fixing a few bugs with timestamps
and directory deletion.
Changes since 0.35:
* Fixed SVN log GMT timestamp conversion.
* Fixed issue with sub-dirs of deleted dir not being removed in some cases.
Version 1.5.5beta01 [July 13, 2011]
Fixed some typos and made other minor changes in the manual.
Updated contrib/pngminus/makefile.std (Samuli Souminen)
Version 1.5.5beta02 [July 14, 2011]
Revised Makefile.am and Makefile.in to look in the right directory for
pnglibconf.h.prebuilt
Version 1.5.5beta03 [July 27, 2011]
Enabled compilation with g++ compiler. This compiler does not recognize
the file extension, so it always compiles with C++ rules. Made minor
changes to pngrutil.c to cast results where C++ expects it but C does not.
Minor editing of libpng.3 and libpng-manual.txt.
Version 1.5.5beta04 [July 29, 2011]
Revised CMakeLists.txt (Clifford Yapp)
Updated commentary about the png_rgb_to_gray() default coefficients
in the manual and in pngrtran.c
Version 1.5.5beta05 [August 17, 2011]
Prevent unexpected API exports from non-libpng DLLs on Windows. The "_DLL"
is removed from the test of whether a DLL is being built (this erroneously
caused the libpng APIs to be marked as DLL exports in static builds under
Microsoft Visual Studio). Almost all of the libpng building configuration
is moved from pngconf.h to pngpriv.h, but PNG_DLL_EXPORT remains in
pngconf.h, though, so that it is colocated with the import definition (it
is no longer used anywhere in the installed headers). The VStudio project
definitions have been cleaned up: "_USRDLL" has been removed from the
static library builds (this was incorrect), and PNG_USE_DLL has been added
to pngvalid to test the functionality (pngtest does not supply it,
deliberately). The spurious "_EXPORTS" has been removed from the
libpng build (all these errors were a result of copy/paste between project
configurations.)
Added new types and internal functions for CIE RGB end point handling to
pngpriv.h (functions yet to be implemented).
Version 1.5.5beta06 [August 26, 2011]
Ensure the CMAKE_LIBRARY_OUTPUT_DIRECTORY is set in CMakeLists.txt
(Clifford Yap)
Fixes to rgb_to_gray and cHRM XYZ APIs (John Bowler):
The rgb_to_gray code had errors when combined with gamma correction.
Some pixels were treated as true grey when they weren't and such pixels
and true grey ones were not gamma corrected (the original value of the
red component was used instead). APIs to get and set cHRM using color
space end points have been added and the rgb_to_gray code that defaults
based on cHRM, and the divide-by-zero bug in png_handle_cHRM (CERT
VU#477046, CVE-2011-3328, introduced in 1.5.4) have been corrected.
A considerable number of tests has been added to pngvalid for the
rgb_to_gray transform.
Arithmetic errors in rgb_to_gray whereby the calculated gray value was
truncated to the bit depth rather than rounded have been fixed except in
the 8-bit non-gamma-corrected case (where consistency seems more important
than correctness.) The code still has considerable inaccuracies in the
8-bit case because 8-bit linear arithmetic is used.
Version 1.5.5beta07 [September 7, 2011]
Added "$(ARCH)" option to makefile.darwin
Added SunOS support to configure.ac and Makefile.am
Changed png_chunk_benign_error() to png_warning() in png.c, in
png_XYZ_from_xy_checked().
Version 1.5.5beta08 [September 10, 2011]
Fixed 64-bit compilation errors (gcc). The errors fixed relate
to conditions where types that are 32 bits in the GCC 32-bit
world (uLong and png_size_t) become 64 bits in the 64-bit
world. This produces potential truncation errors that the
compiler correctly flags.
Relocated new HAVE_SOLARIS_LD definition in configure.ac
Constant changes for 64-bit compatibility (removal of L suffixes). The
16-bit cases still use "L" as we don't have a 16-bit test system.
Version 1.5.5rc01 [September 17, 2011]
Removed "L" suffixes from constants in pngpriv.h
Version 1.5.5 [September 22, 2011]
No changes.
August 19, 2011: Release 1.10
A DXF backend was added. The output is in the drawing interchange
format used by computer aided design software. Thanks to Jonas
Benedett Dorr for testing. The Gimppath backend was changed to be
compatible with current versions of Gimp. The EPS, PDF, and SVG
backends now use high-resolution bounding boxes. The default scaling
of the EPS, PDF, and SVG backends is now fixed at 72dpi. A new option
--flat was added to the SVG backend. A new option --tight was added
to remove whitespace around the input image before calculating its
scaling and placement.
December 21, 2010: Release 1.9
The xfig and eps backends were improved, and a fixed pagesize PDF
backend was added. Support for BMP version 4 and version 5 files, as
well as top-down BMP files, was added. Minor speed improvements to
Potrace and major speed improvements to mkbitmap. A Gaussian blur
option was added to mkbitmap. Libtool is now used to build and
optionally install the Potrace library. An optional simplified
progress bar was added for dumb terminals. This release also contains
some portability improvements, cross-compilation improvements, and
minor bug fixes.
changes:
-Tags can now be organized into hierarchical trees
-Paired RAW + JPEG images are treated as a single photo when imported
from a camera
-Select different developers for RAW photos: use the development produced
by Shotwell or by your camera
-Shotwell now uses GSettings instead of GConf to store its
configuration information
-"Hide Photos Already Imported" setting persists between imports
-Several all-new saved search options
-JPEG mimics of RAW images are no longer stored in your home directory,
and are now created on demand
-Shotwell now supports Windows Bitmap (.bmp) images
changes:
-Imported dcraw 9.10 (1.444)
-Bugfix: green matching is turned off if output image is shrinked due to
wavelet filtering or aberration correction
