Changes for version 3.0.1

   * FormKeyError was in the wrong place in the pse.conf file, and
     it didnt work anyway.  It is now in the plugin.request section
     where it belongs.
   * PSE will no longer die if a custom tag import fails.
   * Session cookies now expire properly according to pse.conf.
   * api.write_error will no longer fail if a string was not passed.

Changes for version 3.0.0

   * PSE now requires at least Python 2.3.1.  Python 2.3.0 and older
     versions of Python are no longer supported.
   * PSE is now thread safe for use with multithreaded apache 2.0 mpm
     modules.  If you decide to use a multithreaded mpm, be sure your
     plugins, custom tags and other modules used in your applications
     are also thread safe.
   * The name of the pse handler for mod_python has changed to
     pse_handler.  See UPGRADING.TXT for more information.
   * PSE no longer uses the PythonAccessHandler directive in the
     apache configuration file.  You must delete these references.
   * Authentication hooks have been removed from PSE.  See the manual
     for use of the new pse.plugins.response.authenticate function.
   * A new function pse.call() works like pse.include(), but it runs
     code in a separate namespace.  Please see the PSE Manual for
     details.
   * PSE handles unicode better than previous versions.  The default
     encoding can be set with DefaultEncoding in pse.conf, which can
     be changed per servlet using the pse.setencoding() function.
     Please see the pse.conf file and the PSE Manual for details.
   * A new funtion pse.flush() will flush client output immediately,
     but any operations to alter headers will then raise an exception.
   * The plugin architecture has changed significantly.  While plugins
     made for PSE 2.x will continue to work, much of the functionality
     is deprecated.  See UPGRADING.TXT and the PSE Manual for details.
   * The pse.conf file has been reorganized.  Specifically, many
     options were moved to the Debug section.  Please see the pse.conf
     file for details.
   * User plugins can be placed in directories other than in the
     PSE distribution package directory; see pse.conf for details.
   * The session plugin type can now be configured in the pse.conf
     file rather than manipulating the modules in the PSE plugins
     directory; see the PSE Manual for details.
   * The SQLite session plugin now requires at least SQLite 3.0 and
     version 2.0 or higher of the Python bindings (pysqlite2).
   * User plugins can be disabled in the pse.conf file by specifying
     "Enabled = no" in that plugin's configuration section.
   * pse.plugins.response.redirect can now redirect requests in
     different ways.  See the PSE Manual for details.
   * Access to form data using pse.form is deprecated; use
     pse.plugins.request.form instead.
   * The cookie interface in pse.plugins.client was broken in 2.x;
     CookieDef was not available to create new cookies.  The class name
     has been changed to CookieClass and is now exposed to be able to
     create and store new cookies.  See the PSE Manual for details.
   * Custom tag classes can cause PSE to suspend its processing of
     text within the tag; see the PSE Manual for more information
   * Raw HTTP POST data can now be obtained from
     pse.plugins.request.content, a file-like object, for use with
     XML-RPC or other applications.
   * Unicode output is now passed through instead of being converted
     to a string.
   * Cached output is now stored in a separate directory from the
     PSE template files; see pse.conf and the PSE Manual for details.
   * Servlets compiled with the psecompile utility now compile to
     .pto files, not to be confused with the old "cache" .pto files.
   * Tracebacks no longer contain internal PSE frames leading up to
     the running servlet's first frame.
   * Added TraceAll to pse.conf to force PSE to attempt to show a
     traceback even when the source is not available.
   * A new api module was added to aid in the development of plugins
     and custom tags.  Please see the PSE Manual for details.
   * Many bug fixes and code optimizations were completed.
   * PSE includes an experimental CGI script that can be used when
     mod_python is not available.  WARNING: THIS IS EXPERIMENTAL!!
     Please report bugs to pse.info@borko.org.

Changes for version 2.2.2

     original source .pt file is absent.
   * Included debian package stuff, suitable for building
     debs for unstable(sid) debian.

Changes for version 2.2.0

   * pse.conf is now expected to be in /etc/pse/ or in a similar location,
     depending on where Python is installed (e.g. /usr/local/etc if Python
     was installed in /usr/local), as opposed to being in the pse
     package directory.
   * The compile utility has been renamed to psecompile.
   * _dbhash-session.py no longer exists in plugins.  It is now the
     default session.py modules.
   * PSE will no longer log the perror string for most log entries.
   * Fixed bug with <br /> being convertedto <br></br>.
   * The pserun utility no longer requires a fake _apache.py module.

     tarballs to be made.

     routines now get reported.
   * PSE now supports XML processing tags beginning with "<?xml".
   * Session cookies will now always be set for each request, regardless
     of error state.
   * PSE has been tested with Apache on Windows. The dbhash session
     plugin has been modified to work in Windows.  The Win32 extensions
     for Python must be installed to work correctly.
   * The global session namespace can now be cleared by calling
     pse.session.delete with no parameters.
   * For custom tag modules, tag_hooks is no longer required, and its
     use is now depricated.  Please see the PSE Manual for more
     information.
   * Form processing now results in PSEstr and PSElist objects instead
     of normal strings and lists.  Please see the PSE Manual for more
     information.
   * Numerous bug fixes and documentation updates.
   * NEW: Added PreImport option in pse.conf to pre-import modules for each
     request (modules must be on sys.path), to reduce page response time.
   * NEW: Compiled code memory caching can be controlled using CacheSize
     option in pse.conf.
   * NEW: Accessing the pse.form dictionary with an invalid key no
     longer raises a KeyError by default.  You can revert this by
     specifying FormKeyError=Yes in pse.conf.  Please see the PSE Manual
     for more information.

Changes for version 2.0.0

   * This is the first Open Source version of PSE.
   * This version contains some MAJOR CHANGES that may break existing
     servlets written for PSE 1.2.x and below.
     !!!! Please read UPGRADING.TXT for more information. !!!!
   * MAJOR CHANGE: The leading ? indicator templates from version 1.2
     and below longer evaluates Python code in tag attribute values.
     Instead, it indicates a condition in which the attribute appears
     at all.  This is for boolean attributes such as SELECTED and
     DISABLED.  Please read the documentation for more details.
   * MAJOR CHANGE: All plugins now appear in the pse.plugins package
     as opposed to appearing directly as sub-modules of the pse module
   * MAJOR CHANGE: The pse.include() function now returns a string
     instead of printing output directly as a result to allow better
     integration with Custom Tags

     you must delete all compiled servlets and/or recompile them to
     take advantage
