Release Name: 0.4.0

Notes:
Version 0.4 of the of the Sedna XML database client library for Ruby has been
released! This version adds an alternative style of specifying transactions,
non-blocking behaviour for initiating new connections, a method to reset the
current database connection, and some other small improvements. See the file
CHANGES for details. Version 0.4 has been fully tested in Ruby 1.8.5 and
above, including the latest release candidate of Ruby 1.9.1.


Changes:
* Released on January 4th, 2009.
* Added Sedna#reset, which closes the current connection and reconnects.
* Added Sedna#connected?, which returns whether or not the current connection
  is still active.
* Sedna#transaction can now also be used without a block. Use the newly added
  methods Sedna#commit and Sedna#rollback to finish such a declarative
  transaction. Note that this style is not recommended if a transaction can
  be wrapped in a block.
* Sedna.connect no longer blocks other threads in Ruby 1.9.1+. Use Sedna.blocking?
  to discover if support for non-blocking behaviour is enabled.
* Strings in the result Array of Sedna#execute are now in UTF-8 encoding in
  Ruby 1.9, rather than binary.
* Fully tested in Ruby 1.8.5+ (including the latest version, 1.9.1 RC1).
* Now also compiles with Ruby 1.9.0.x, but non-blocking behaviour is disabled
  for these versions.
