All whitespace in object names is now converted to a compacted format with whitespace replaced with hyphens. If a conversion takes place, a warning is logged. Converted some of the tests into C++ as they directly include .cc files.

MariaDB MaxScale 2.2.0 Release Notes
Release 2.2.0 is a Beta release.
This document describes the changes in release 2.2.0, when compared to release 2.1.X.
For any problems you encounter, please consider submitting a bug report at Jira.
Changed Features
Whitespace in Object Names
Significant whitespace in object names is now deprecated. All object names (services, servers, etc.) will be converted to a compatible format by squeezing repeating whitespace and replacing it with hyphens. If any object name conversions take place, a warning will be logged.
NamedServerFilter
This filter now uses the PCRE2-libarary to match queries. Previously, it used the POSIX-version of PCRE2. The filter also accepts multiple match-server pairs. Please see the NamedServerFilter documentation for details.
Dropped Features
MaxAdmin
The following deprecated commands have been removed:
enable log [debug|trace|message]disable log [debug|trace|message]enable sessionlog [debug|trace|message]disable sessionlog [debug|trace|message]
The following commands have been deprecated:
enable sessionlog-priority <session-id> [debug|info|notice|warning]disable sessionlog-priority <session-id> [debug|info|notice|warning]
The commands can be issued, but have no effect.
MaxAdmin no longer attempts to interpret additional command line parameters as a
file name to load commands from (e.g. maxadmin mycommands.txt). The shell
indirection operator < should be used to achieve the same effect (maxadmin < mycommands.txt).
New Features
MySQL Monitor Crash Safety
The MySQL monitor keeps a journal of the state of the servers and the currently elected master. This information will be read if MaxScale suffers an uncontrolled shutdown. By doing the journaling of server states, the mysqlmon monitor is able to keep track of stale master and stale slave states across restarts and crashes.
Avrorouter deflate compression
The Avrorouter now supports the deflate compression method. This allows the
stored Avro format files to be compressed on disk. For more information, refer
to the Avrorouter documentation.
Preliminary proxy protocol support
The MySQL backend protocol module now supports sending a proxy protocol header to the server. For more information, see the server section in the Configuration guide.
