2.0.2

This version was not released

2.0.1

changes since 2.0.0

Bug fixes

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

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.

  • Changed namespace from casa to casacore (but still #defined as casa for time being)
  • Split Tables, MeasurementSets and Lattices into smaller parts

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
