2.0.0

changes since 1.7.0

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.

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

Added persistency for ImageExpr and ImageCocat objects

Python

Moved converters from pyrap to casacore/Python
