For instance, when moderating say 50 mails in week 1 and 50 mails in week 2, the digest mail in week 1 will contain say 30 mails in a digest, while the digest in week 2 will contain like 20 mails from week 1 and like 10 mails from week 2.

My best guess is you are triggering digests on size (Digest options ->
digest_size_threshold) and either not periodically (digest_send_periodic
= No) or cron/senddigests runs only weekly.

50 messages are approved; the 30th message triggers a digest on size.
And the remaining wait until digest_size_threshold is reached again.
Then the next week a bunch more messages are approved and the 10th
message triggers a digest on size and the rest wait and until either
threshold is reached again or a periodic digest is sent.

As to why this is changed behavior, perhaps after the upgrade,
cron/senddigests is not being run for some reason to produce a daily
digest. Check Mailman's crontab, Mailman's error log and the system cron
