Looks like the reason for this file has gone.  We shall merge
the code into config.inc soon.

pconfig_to_address, don't save range when $endport is 0, closes https://github.com/opnsense/core/issues/1611

filter, alias, don't reload immediately after delete, closes https://github.com/opnsense/core/issues/1601

webgui, refactor rc.php_ini_setup into standard template, rename webuicompression to compression and split help text

webgui, allow use of output compression for dynamic content. in same cases saves approx. 90% of datatransfer to client, at some cpu cost. default Off

This reverts commit 6eda8aec.

CARP, add option "Disable preempt", move preempt to later boot stage. for https://github.com/opnsense/core/issues/1557

If configd doesn't respond the JSON is not available, which we really
need a wrapper for doing this fallback all the time and maybe even
with error reporting inside that returned array.

OpenVPN servers using udp6 or tcp6 fail to start, closes https://github.com/opnsense/core/issues/1576

Seems like years ago when PHP 5.5 had trouble iterating non-
existing arrays PHP 7 introduced a new problem with nodes
that seem to be set but no longer available, yielding:

    PHP Warning:  OPNsense\Base\FieldTypes\InterfaceField::eventPostLoading():
      Node no longer exists in /usr/local/opnsense/mvc/app/models/OPNsense/Base/FieldTypes/InterfaceField.php on line 132

The same thing happened in the acme-client plugin and was
allegedly fixed with the following code.  Even if this doesn't
help it is harmless and we'll see through the crash reporter
soon enough.

Now that tools can build several versions of the same software, we
can have -devel depend on a different one than the release.  This
helps with prebuilt testing and easier testing for interested parties.

Should your manual upgrade break at the moment, the easiest solution is:

    # make upgrade CORE_OPENVPN=23
