I keep my change logs inside the featured mission pop file, they go as follows:
//Changelog A2
//--map changes
//fixed a glitch/naming oversight that would make burning gatebots ignore gate B after gate A is capped
//fixed chaos mode bugs with gatebots
//capping gate A opens the small side doors for small bots to go through, but giants will still prefer take the long way unless they have the bomb
//altered tank paths, they no longer go through a gate that can't be opened lol
//Expanded and reworked the front, moved the tanks closer to the gates
//Made the map overall asemmetrical
//removed the gate, and replaced it with a stuck version that only players can jump through
//--Mission changes
//Overloading heavies are now called heavies rather than soldiers
//swapped wave 3 and wave 2
//swapped wave 4 and wave 5
//The Gatebot KGB's still have soldier gatebot hats after capping A, I left this in because I felt it was funny, deal with it
//Wave 2-escape plan soldiers are no longer part of a subwave and spawn slower, reduced their count. Reduced Mannmelter pyros counts, reduced KGB support heavies by 1 bot, and greatly reduced the scout mission supports
//wave 4-added another subwave (this wave was really short and likely too easy)
//Wave 5-added support burning heavies that start spawning on the 2nd subwave, increased max gatebot backups to 15
//Wave 6-added gatebot backups to the 2nd subwave
//Wave 7-made this wave "harder", added fallout jokes
