January 26, 2016:

Libgta 1.0.8 is released. The only change is a small bug fix for cmake-based builds.

Gtatool 2.2.0 is released. This is a cleanup release that removes support for Qt older than 5.5 and removes the ill-conceived view command that never really worked as expected. Furthermore some incompatibilities with current versions of libraries have been fixed.

December 20, 2014:

Gtatool 2.1.0 is released! New in this release is import/export of PNG images directly via libpng, and support for 128-bit integers and quadrupel precision floating point values on most platforms.

December 17, 2014:

Libgta 1.0.6 is released! A few potential memory leaks have been fixed, and a missing error check was added. These problems were found by the scan-build static analyzer. Additionally, unnecessary non-null pointer restrictions have been removed from a few gta_* functions. This release is completely compatible to previous versions.

Update: version 1.0.7 was released shortly after 1.0.6, to fix a small build problem. There are no other changes.

September 26, 2014:

Gtatool 2.0.1 is released! This version only fixes a build problem, nothing else changed.

September 23, 2014:

Gtatool 2.0.0 is released! This release contains a lot of improvements. The biggest change is the new view command, which launches an OpenGL-based data viewer. This command is still in alpha stage, but already useful for 2D arrays. It will be extended in future releases.

March 9, 2014:

Libgta 1.0.5 is released! Support was added for building libgta with CMake, as an alternative to the GNU autotools. Libgta can now be built with Visual Studio 2013 (using the pre-built library with any Visual Studio version was already possible before). The GNU autotools files have been updated. This release is completely compatible to the previous version.

April 29, 2013:

Gtatool 1.5.2 is released! This version fixes a number of minor bugs and removes some restrictions.

February 10, 2013:

Gtatool 1.5.1 is released! This version fixes a few portability problems. The GUI now watches files and reloads them automatically when they are changed on disk.

February 2, 2013:

Gtatool 1.5.0 is released! This version can automatically detect the file format for import/export and adds the new commands stream-foreach and stream-grep. Furthermore, the GUI is improved and several problems are fixed.

January 26, 2013:

Gtatool 1.4.0 is released! This version adds new commands diff and combine, improves the GUI for GTA files with many arrays, and fixes several minor problems.

December 8, 2012:

• Libgta 1.0.4 is released! This version improves compatibility with Windows compilers, especially newer Visual Studio versions. The FindGTA.cmake file for CMake users was updated.
• Gtatool 1.3.1 is released! This version fixes several problems, including broken import via FFmpeg.

December 3, 2012:

Gtatool 1.3.0 is released! This version adds import/export filters for NetCDF files (including many HDF4 and HDF5 files) and improves the PLY and PCD import/export filters.

September 3, 2012:

Packages for Ubuntu 12.04 are now available from this PPA: http://launchpad.net/~marlam/+archive/gta.

September 3, 2012:

Gtatool 1.2.0 is released! This version adds import/export filters for JPEG images and for volumetric data in PVM or .dat/.raw format. Furthermore, a few minor problems were fixed.

September 2, 2012:

Libgta 1.0.3 is released! This version fixes a few minor problems, one of which prevented the test suite to run properly.

July 18, 2012:

Gtatool 1.1.0 is released! New features include import and export filters for CSV and NRRD files. The GUI and the raw binary filter were improved. Several smaller bugs were fixed.

February 18, 2012:

The following projects have added support for the GTA file format via libgta:

• The Geospatial Data Abstraction Library (GDAL). See their format documentation.
• The OpenSceneGraph (OSG) graphics toolkit. Support for a GTA ReaderWriter plugin is in the current SVN version.

January 27, 2012:

Libgta 1.0.2 and gtatool 1.0.2 are released.
These updates fix a few minor build and portability issues. An update is unnecessary if you did not run into problems with the 1.0.1 releases.

December 11, 2011:

• Libgta version 1.0.1 is released.
  This update fixes a few bugs that caused libgta to crash on invalid input. An update is recommended.
  To help prevent this kind of problem in the future, automatic fuzz testing via make fuzztest was added.
• Gtatool version 1.0.1 is released.
  The component-based commands now use better buffering and are therefore faster than before. Building gtatool does not require C++11 anymore.

December 4, 2011:

Finally, both libgta and gtatool reached version 1.0.0.

There were no changes to the file format or the libgta API/ABI since 0.9.4. Future versions will remain compatible with this release.

Gtatool can now import/export multimedia data (via FFmpeg and libsndfile) and point cloud data (via PLY and PCL). Furthermore, existing commands for array manipulation were improved.

May 21, 2011:

New versions of both libgta and gtatool were released today.

• libgta-0.9.4: A few minor API tweaks were made, and element based input/output is now buffered. This is the third release candidate for 1.0.0.
• gtatool-0.9.4: Several bugs were fixed, and many commands are now faster than before.

August 22, 2010:

New versions of both libgta and gtatool were released today.

• libgta-0.9.3: Some compression-related fixes and tweaks were made. This is the second release candidate for 1.0.0.
• gtatool-0.9.3: Some minor improvements and tweaks were made, but no new features were added.

June 26, 2010:

New versions of both libgta and gtatool were released today.

• libgta-0.9.2: The documentation was improved and more examples were added. Two helper functions were added to the interface. This version is a release candidate for 1.0.0.
• gtatool-0.9.2: New commands were added to import and export MATLAB .mat files and RAT RadarTools .rat files. The GUI was improved significantly.

June 13, 2010:

New versions of both libgta and gtatool were released today.

• libgta-0.9.1: A few minor adjustments to the API and file format were made. If no suggestions for further changes are made, these are probably the last changes before version 1.0.0.
• gtatool-0.9.1: Many changes were made. The most significant addition is the new gui command that provides a graphical user interface for most gtatool commands.

May 7, 2010:

The GTA project made the initial public releases: libgta version 0.9.0 and gtatool version 0.9.0.

Both packages are fully functional. The plan is to make corrections and changes during the 0.9.x series where necessary. At the time of the 1.0 release, both the GTA file format specification version 1 and the libgta API/ABI will be frozen, and all future releases will be backward compatible if at all possible.
