The latest version of QGIS, version 2.8 aka QGIS Wien, has been released. Besides along list of new features and improvements (check out the visual change log), this is also the first release designated an ‘LTR’ (Long Term Release).
LTR releases will be supported with backported bug fixes for one year, and will be in permanent feature freeze (i.e. no new features will be added, only bug fixes and trivial updates). This may be particularly important for enterprises and organisations that do not want to deal with updating user skills, training materials etc. more than once per year.
The list of new features and improvements is really too long to summarize here, and there are too many to pinpoint one favourite. So instead I would say, check it out yourself!
It has taken many years of development, but finally the new stable major release GRASS GIS 7.0.0 is available. Many congratulations to the developers, they did an incredible job. This version provides numerous new functionalities, including completely new modules (e.g., the spatio-temporal database support) and massive improvements in data handling, with support for massive vector layers and speed improvements.
Check out the press release and the list of new features. But most of all, make sure you download the new version, if you have not done so already, and start enjoying a whole new experience.
The second release candidate of the upcoming stable GRASS GIS 7.0.0 version has been released. You can read the announcement here (including the download links) or the more detailed news about the release candidate here.
If you are still using GRASS 6.4, this long list of new features and improvements implemented in GRASS GIS 7 will give you plenty of reasons why you should try out the latest and greatest.
Riitters et al. (2000) proposed a quick approach to measure the degree of forest fragmentation that could be relatively easily implemented and which only required a map with forest and non-forest. Following their approach, Sylla consult created a shell script for GRASS GIS 6.4 to create a raster layer with six categories (non-forest, patch, transitional, edge, perforated, interior and undetermined) as a measure of forest fragmentation. See their blog post with an explanation how the script works or the above-cited article for a more in-depth description.
I adapted the script to make it work on GRASS 7.0, including some further improvements, such as the option to select the size of the moving window, the option to trim the output layer to avoid the edge effect that comes with moving-window calculations and the option to keep intermediate layers.
I have now rewritten the script as a Python addon. See here for the manual page. Continue reading Update of r.forestfrag addon for GRASS GIS 7.0
GRASS 7 sports very significant improvements and numerous new functions. For example, the improved graphical user interface makes it much easier to carry out complex GIS operations and handling of vector data has become much faster and more efficient with very large files. There is a large number of new analytical raster and vector modules and existing modules are now much faster (some even 1000 x faster). Beta 3 ships 390 fixes and improvements with respect to beta 2.

Just a few days after the release of GRASS GIS 6.4.4, now the latest and greatest QGIS Chugiak. And this new version comes with a whole bunch of improvements and new features. Check out this nice visual visual changelog of the major changes or go straight to the download page to try it out yourself.
Are you one of those people eagerly waiting for all those new features in QGIS that have been mentioned in the last couple of months on various forums and blogs? Well, the waiting is (almost) over. QGIS 2.2 is already available in OSgeo4W, Fedora, and Debian, while binary packages are being updated and will be available any time (or might already be available by the time your read this) on qgis.org.
