* There is now a ZPT Reference to go along with the DTML and API
    references in the online help system.

  * I changed the titles of some TAL and METAL help topics to make
    them look better in the help system.

Add some comments that make it clear that the traceback object is not
referenced when the function exits.

This code was correct, because of the outer try/finally that set tb to
None.  This change localizes the handling of the traceback, so that
it's safety can be determined by local inspection.

for object expiry.

did not show  the Webdav LockManager entry in the control panel

  - "active" in detailed output is now slightly more meaningful.
    It is > 0 only if other requests started after it started
    but before it finished.  The greater the active count, the
    more likely it is that something was going on at the time
    in which the request ran that caused a slowdown.


  - multiple files may be analyzed at the same time.

Also, script recognizes "U" opcode in big M logs as meaning a restart.

- Implemented stemming in a simpler way.

- Made checkSynword() easier to read.

- Used PyList_GetItem() to do bounds checking in Splitter_item().

- Made Splitter_indexes slightly faster by keeping a local copy of the length.

- splitUnicodeString() now returns -1 on error.

- Made splitUnicodeString() easier to read.

- prepareString() performs a copy the standard way.

This silences a DeprecationWarning when running the Zope tests.  It's
kosher, because the trunk requires Python 2.1.

This silences extraneous output when running the TAL tests with a
Python without expat.

Application instance on the fly.

their disobedience.

- Made some corrections to the DTML tests, which aren't currently working
in testrunner but work when run directly. ??

  - Remove the need to 'import Zope' in one of the last tests which
    does so (ZCatalog tests still need it, on account of ZClass
    base class stuff).

- added script to recreate regression reference files
- added another test

s Appendix B.

Added documentation for the AccessControl.getSecurityManager function and the SecurityManager class. They are usuable from Python-based scripts and ZPT.

- Revert to old Unauthorized exceptions when zExceptions module is not present.
