New Features
------------


New or modified Configurations
------------------------------

Combined Connect Timeouts
^^^^^^^^^^^^^^^^^^^^^^^^^

The configuration settings :ts:cv: `proxy.config.http.parent_proxy.connect_attempts_timeout` and :ts:cv: `proxy.config.http.post_connect_attempts_timeout` have been removed.
All connect timeouts are controlled by :ts:cv: `proxy.config.http.connect_attempts_timeout`.

Logging and Metrics
-------------------

Plugins
-------

Switch to C++17
^^^^^^^^^^^^^^^

Plugins are now required to be compiled as C++ code, rather than straight C.
The API is tested with C++17, so code compatible with this version is preferred.
``TSDebug`` and related functions are removed.  Debug tracing should now be done
using cpp:func:`Dbg` and related functions, as in |TS| core code.

C++ Plugin API Deprecated
^^^^^^^^^^^^^^^^^^^^^^^^^

It is deprecated in this release.  It will be deleted in ATS 11.

Symbols With INKUDP Prefix
^^^^^^^^^^^^^^^^^^^^^^^^^^

In the plugin API, all types and functions starting with the prefix INKUDP are removed.
