- Support for cross-platform compilation using cross-mingw32 (build instructions in README).
- Some bugs were fixed in the library, related to memory allocation. Now lensfun should be valgrind-clean.
- Fixed a nasty bug in lfDatabase::FindLenses() that would always use fuzzy search (even if you would ask for a 100% match). Your applications may chease to "find" lenses if they relied on this bug. Just add the LF_SEARCH_LOOSE flag as the last parameter to return the old behaviour.
- Fixed another bug in search logic that sometimes would mark unappropiate results with very high scores (esp. when little search keywords are given). Now search should work much better.
- New TCA correction algorithm: LF_TCA_MODEL_POLY3 ("poly3" in database). This is almost the algorithm used by Hugin except the highest-order power (r^4). This should allow users to use tca_correct to compute TCA parameters.
- Fixed the LF_TCA_MODEL_LINEAR - it used 1/k where it was expected to use k. This is the 'v' parameter of Hugin TCA model, and previously users had to invert v to get k; now they can just use v.
- New lens calibration tutorial, using Hugin.
- Some SSE & SSE2 support from Klaus Post with runtime CPU features detection.
