Differences between releases

Hi Folks,
My topology consists of 1JMS and 1JVB2.

JMS
jitsi-meet 2.0.4857-1
jitsi-meet-prosody 1.0.4289-1
jitsi-meet-web 1.0.4289-1
jitsi-meet-web-config 1.0.4289-1
jitsi-videobridge2 2.1-273-g072dd44b-1

JVB2:
jitsi-videobridge2 2.1-273-g072dd44b-1

I should add 2 more JVB2.
However when I check the newer versions are different from I use.
If I download the newer verison of JVB2, does it work with my JMS?
or how can I download specific version 2.1-273-g072dd44b-1 ?
