New in version 2.5.4

  • Added jsonb support for PostgreSQL 9.4 (ticket #226).
  • Fixed segfault if COPY statements are passed to execute() instead of using the proper methods (ticket #219).

  • Cursors WITH HOLD don't begin a new transaction upon move/fetch/close (ticket #228).

  • callproc() doesn't silently ignore an argument without a length.
  • Fixed memory leak with large objects (ticket #256).

New in version 2.5.2 (January 8th, 2014)

  • Fixed segfault pickling the exception raised on connection error (ticket #170).
  • Meaningful connection errors report a meaningful message, thanks to Alexey Borzenkov (ticket #173).

New in version 2.4.2 (June 14th, 2011)
