New Features:
-------------
  - None
Bug Fixes:
----------

  - Fixed incorrect list quoting for "filter" in urlspace
    introspection. This led to display problems, e.g. in the nsstats
    module.

  - Fixed naming Inconsistency: Unified the term "fastpath" across
    configuration, API-interface, and documentation.

  - Fixed potential crash in Ns_SetIUpdateSz(): Fixed a bug that could
    lead to a crash when updating the content-type header field with a
    lowercase field name via the old C API.

    Many thanks to Brian Fenton for reporting the problem and his help
    for debugging it.
Code Maintenance:
-----------------

  - New API Function Ns_PlainUrlPath: Checks if a given URL path is
    "plain," meaning it doesn't contain a query or fragment. Useful
    for data validation in configuration files and Tcl API calls.

  - Improved Validation when registering request handler. Previously,
    it was possible to register request handlers for paths containing
    query variables and fragments, which were never matched.

  - Added Missing "-server" Argument: The "-server" argument was added
    to ns_unregister_op and ns_unregister_url2file, allowing for more
    centralized management (e.g. from the nsstats module).

  - Added a more Portable Way of Printing NULL Pointer: Improved
    portability for printing NULL pointers across different compilers,
    which could lead to false positives in the regression test.

  - Extended and Simplified Test Cases: Several commits were made to
    improve and extend test cases across different modules and
    scenarios.

  - Improved and corrected documentation, including styling changes,
    bug fixes, and providing more detailed information.
Modules:
--------
The following list contains the most important changes:

 - Extending nsstats:

   * Introduced templating to improve style-ability
   * Provided a more modern GUI based on the CSS classes from w3schools
   * Added management of request handlers
   * Added management of url2file mappings

 - Rework of module nsdbbdb:
    * properly initializing mutex variables (many thanks to John Buckman)
    * support for LMDB (Lightning Memory-Mapped Database)
    * Improved configurability for Makefile
    * Modernization of C code (better following style guide)
    * Added debug support via Debug(bdb)

     Build nsdbbdb with Berkeley DB 6.2.32 (results in nsdbbdb.so)
        make DBINCLUDE=/opt/local/include/db62  DBLIB=/opt/local/lib/db62/

     Build nsdbbdb with LMDB (Lightning Memory-Mapped Database) (results in nsdblmdb.so)
        make LMDB=1 DBINCLUDE=/opt/local/include DBLIB=/opt/local/lib/
