- Replaced references to pyrap -> casacore (issue 16)
- Experimental support for Python3 (needs python3 branch build of casacore)
- Link against correct Python on OSX when using homebrew (issue 15)

General
- Merge of CASA work into casacore, CASA should compile with casacore now
- Under-the-hood optimizations, like using allocator features (132)
- Building with gcc 5 is now possible (166)
- Compatibility with more versions of wcslib and cfitsio
- SOFA is now an external dependency (105)

Tables
- Arrays can now sometimes be reshaped while keeping allocated memory (113)

MS
- Selection of baselines with a regexp between stations is now possible (99)
- Several new methods to MSMetaData (138)

Bug fixes
- Fix a bug which caused an error with LOFAR measurement sets with
the LOFAR tool msoverview (140)
- Fix a bug where TaQL would not write output when an expression was
used (184)

This version was not released

- Renamed project from pyrap to python-casacore
- Renamed modules from pyrap to casacore
- Added backswards compatible module which imports casacore
- Removed scons build dependency, just use setup.py
- Depends on CASACORE 2.0
- Cleanup of project structure
- Moved development to github

General
- Fixed all build problems for GCC and clang on various platforms
(up to OS-X 10.10)
- Fixed all valgrind issues found in test programs
- Made the statics in all of casacore thread-safe. Similar to
libstdc++ the user is responsible for thread-safety when using
casacore ojbects.
- Added casacore/ to the include path of all header files
- Changed namespace from casa to casacore (but still defined as
casa for time being)
- Split Tables, MeasurementSets and Lattices into smaller parts
- The 3 changes above give rise to backward incompatibilities. Scripts
in casacore/changescripts (notably updateall) can be used to fix
client code.

Tables
- Added GROUPBY/HAVING/aggregation function to TaQL
- Optimized TaQL's IN operator (linear time for integer sets)
- Added table tracing (class TableTrace)
- Fixed TiledStMan issue where BucketCache was not shrinked
- Added MultiFile option to combine table files in a single one

Components
- This module has been removed (too CASA specific)

Images
- Added support for beam per frequency channel and Stokes
- Added persistency for ImageExpr and ImageCocat objects

Python
- Moved converters from pyrap to casacore/Python
