 You need to look into git log to find out the changes.
But if you use Cassandra lib to read the files, CommitLogReader is able to read 
the current and previous version of commit-logs:

 Hello folks,

I am exploring the CDC option to move data from cassandra to Hive on
periodic basis.
While exploring this option, I overheard saying that the internal
commit-log structure will change form version to version. Is this correct?

As per this link
sstables have changed in multiple times in multiple versions.
I want to understand about the commit-log internal structure as well. Is
there any change in the commit-log file structure in different cassandra
versions? If so, can someone please redirect me to the docs/change log?

Please help me to understand more on this. Thanks in advance
