In 2011 when talking about Digia putting out new Qt Commercial releases
with over one hundred changes compared to what's found in the open-source/community Qt repository, many Phoronix readers were upset by this large delta. Digia is still putting out new Qt Commercial releases that carry large differences to the upstream open-source releases, but they've offered up the patches for mainline integration.
When Qt 4.8 was released in December, Digia's commercial version of the tool-kit shipped with "108 improvements and bug fixes available in Qt Commercial 4.8.0 that are not part of the LGPL release." This is what was upsetting to some Phoronix readers
Digia has now shared that they've released Qt Commercial 4.7.5. This time around, the commercial version is still carrying large changes from the last LGPL Qt 4.7.x series release. Fortunately, however, they're working to land the work within the Qt Project.
As mentioned on the mailing list
We have just released Qt Commercial 4.7.5, which is based on Qt 4.7.4, additionally containing the fixes from 4.7 branch that were not in 4.7.4, as well as fixes we have backported from 4.8. Overall Qt Commercial contains 216 fixes to Qt Commercial 4.7.4, and a few more to LGPL version of 4.7.4.
In case there is still interest towards 4.7 in the community, we are happy to make the source code available. What way would you prefer? We can, for example, make this available in gitorious and send the link to the mailing list.
