  ===========================================================================
  
! pyPgSQL v2.1 has been released. It is a bug fix release to version 2.0, but
! also includes some enhancements.
  
  It is available at http://pypgsql.sourceforge.net.

! Announce: pyPgSQL - Version 2.2 is released.
  ===========================================================================
  
! pyPgSQL v2.2 has been released. It is a bug fix release to version 2.1.
  
  It is available at http://pypgsql.sourceforge.net.

*** 40,107 ****
  ===========================================================================
  
! Changes since pyPgSQL Version 2.0
  =================================
  
! pyPgSQL 2.1 is now compatible and tested to work with PostgreSQL 7.2.x.
  
  Changes to README
  -----------------
! * Added documentation for the new TransactionLevel attribute of
! the Connection object.
  
  Changes to PgSQL.py
  -------------------
! * Added code to implement support for setting PostgreSQL transaction
! levels. [Feature Request #481727].
! 
! * Got rid of redundant building and storing of the
! mapping of column names to column positions in the PgResultSet class. Now,
! rows of the same query are instances of a dynamically created class, which
! has this mapping as a class attribute instead of an attribute of the
! instance. This saves a lot of space, and also slightly increases
! performance of cursor fetches.
! 	
! * Fixed the array parsing so it also works with PostgreSQL versions 7.2.x.
! The PostgreSQL developers changed the quoting in the string representation
! of arrays in 7.2 beta cycle: strings are now only quoted when otherwise
! the array representation would be ambiguous. The new parseArray() method
! should handle the old and new way of quoting in arrays. [Bug #539769].
! Also added a new testcase for the ARRAY type.
! 
! * Improved the array parsing, so that it now passes all
! the new mean testcases. Added support for parsing multidimensional arrays.
! Eventually, the array parsing code should go as a support function into
! libpq.
! 
! * Replaced all typechecks with "is" operators instead
! of equals. Mark McEahern had a problem with using pyPgSQL in combination
! with a FixedPoint class where the reason was that the FixedPoint class was
! not comarable to None. The consensus on python-list was that None and all
! types are singletons, so they should be checked using "is", which is also
! faster, because it only checks for object identity.
! 
! * Fixed a couple of problems found by Steven D. Arnold:
! 1. A undefined variable was used in a few places where notices were popped
!    from the notice list.
! 2. Comparisons between 2 PgNumerics gave the wrong result.
! 
! * Fixed problem that occurs when the sum() aggregate returns a
! NULL. [Bug #505162].
! 
! Changes to pgversion.c
! ----------------------
! * Allow for development and beta versions of PostgreSQL
  
! Changes to libpqmodule.c
! ------------------------
! * Removed special escaping of control characters in arrays.
  
! * Added support for two missing OID types: aclitem and macaddr. 
  
! * Applied patch by Chris Bainbridge [Patch #505941] "fix for null bytes in
! bytea".
  
! Changes to pgresult.c
! ---------------------
! * Change the point at which an OID is tested to see if it is a
! Large Object from 1700 to 16383.

  ===========================================================================
  
! Changes since pyPgSQL Version 2.1
  =================================
  
! The following source code files were added to Version 2.2 of pyPgSQL:
! 
!     pyPgSQL.spec	- RPM spec file, contributed by Sean Reifschneider.
  
  Changes to README
  -----------------
! * Added note about case-insensitiveness of column access in PgResultSet.
  
  Changes to PgSQL.py
  -------------------
! * Fixed various problems with the PgResultSet: Column (attribute and
! dictionary) access is now case-insensitive.  A __contains__ method was added
! and the __setattr__ method was fixed. The get method got an optional default
! value parameter.
  
! * Fixed various problems with the PgNumeric type:
!   - Added code to allow a float as an argument to the PgNumeric constructor.
!   - You can now change the precision/scale of a PgNumeric by:
!       a = PgNumeric(pgnumeric, new prec, new scale).
!     This can be used to 'cast' a PgNumeric to the proper precision and scale
!     before storing it in a field.
!   - The arithmatic routines (__add__, __radd__, etc) now ensure that the
!     arguments are properly coerced to the correct types.
!   - Added support for the augmented arithmetic operations (__iadd__, etc).
!   - The math routines would lose precision because the precision/ scale were
!     set to be the same as the first operand.  This is no longer the case all
!     precision is retained for the +, -, and * operations.
  
! * Fixed problem that occurs when a query on an OID field doesn't return any
! rows. [Bug #589370].
! 	
! * Applied patch #569203 and also added __pos__ and __abs__ special methods to
! PgNumeric.
  
! * Ensure proper SQL-quoting of long ints.
  
! Changes to PgSQLTestcases.py
! ----------------------------
! * 14 new tests, mostly for PgNumeric and PgResultSet.
