It's been over a year since the last update, but CMR is working fine with 1.19.2 as far as I'm aware. This update adds a couple new features:
Block chance multipliers! In the block list, you can add a % and a number after the name to increase or decrease the chance of a reward triggering for that specific block. For example, mossy_cobblestone%3 means when you break mossy cobblestone, each reward will have 3x the normal chance of triggering.
New special command, !givemoney. When linked with Vault, CMR can give (or take) money from players directly through Vault rather than needing to use a separate command.
New config option, disableCancelledCheck. When set to true, CMR will not check whether another plugin cancelled the block break. This may be useful if you have a misbehaving plugin on a non-survival server, but is not generally recommended.
CMR is now built with Gradle, meaning it's easier than ever to make and test your own modifications to CMR (and contribute them back )
