2.2.0

General

• Lots of bug fixes and improvements

• Lots of code improvement, optimization and added tests

Measures

• The default search path for measures data is now smaller. The path can
  be set at cmake time by specifying -DDATA_DIR=/path/to/data. This path
  can contain %CASAROOT% which is expanded at run time, to support
  relocatable installations. The measures path can also still be set in

2.0.3

NOTE: this release is not ABI compatible with release 2.0.1

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)

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)

small bugfix release

2.0.1

changes since 2.0.0

Bug fixes

• Does not build if checkout root folder is not named casacore (#79)

casacore 2.0.0

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.

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
