The parameter is now optional and uses the correct file. If defined, it
defines the CA certificate that would be used to verify client
certificate. Client certificate verification doesn't seem to currently
work as that requires a custom verification callback that interfaces with
GnuTLS.
The fix to the bug where peer certificates were validated but not required
caused the default behavior to change. The default should've changed at
the same time the fix was made.
The hard limit of 10 seconds is too strict when taking into account the
fact that infinite refreshes was possible before the bug was fixed. This
also makes testing a lot easier where rapid reloads are necessary.
The settings "match", "exclude" and "options" are now explained once
in the general documentation. The individual filter documentation refers
to the general explanation.
Reduced the default cache size from 40% to 15%. Most cases don't benefit
from that much memory and the defaults have caused problems in live
environments.
The load_persisted_configs parameter now controls whether persisted
runtime changes are loaded on startup. The changes are still generated as
it persists the current state of MaxScale making problem analysis easier.
Fixed the documentation on the arguments to maxkeys, which is a directory,
and added a short paragraph about alternative key file locations. Also
documented that keys are read from the directory where the `datadir`
parameter points to.
Any administrative operation, performed using maxadmin or maxctrl,
that takes longer than the watchdog timeout will cause MaxScale to
be killed and restarted by the watchdog.
The cache size now refers to the total memory used by the cache instead of
the per thread limit. This makes it easier to use as well as more
predictable by removing the dependency on the number of worker threads.
Explicitly state that servers only require `ssl_ca_cert` and that
`ssl_cert` and `ssl_key` are optional in certain cases. Updated the
wording of all parameters and removed obsolete or false documentation.
