Missing IPs after update on 2023-12-12

Hi,

After update on 2023-12-12 (https://github.com/ipapi-is/ipapi/commit/6a956658ba9a8dfb956bf3f87d6d0d7be47b1a00) I see a lot of IP misses even though this update has more rows.

Questions
1. What exactly is the change and is that expected?
2. Would be great with some kind of CHANGELOG or description in the commit with a change info (if possible)
