Important note: With the 6.1 release we have changed registration keys. The new key is available for registered users from our Customer Portal. Users upgrading from a pre-6.1 version should have the new key available before installing. Until Monyog is registered with the new key, it will not be collecting data from your servers.
Changes (as compared to 6.2) include:
* Monyog can now resend alert notifications till a counter becomes stable based on a reminder interval setting.
* 'Upgrade check' link in 6.21 informed that an "undefined" upgrade was available even though it was not the case.
* Performance-schema -based sniffer failed if global sql_mode included "ONLY_FULL_GROUP_BY".
