Map Dota 6.60b adalah hasil penyempurnaan dari map sebelumnya, yaitu map Dota 6.60 (bukan Dota 6.60 hacked version lho...) dan di map 6.60b ini beberapa bug Dota 6.60 telah di hapus ato di fix. Jadi, kamu ga perlu khawatir lagi dengan bug ataupun fatal error yang mungkin biasa terjadi di Dota 6.60

Dota 6.60b memiliki beberapa changelogs, berikut kutipan changelogs-nya yang aku ambil dari GetDota (official Dota-Allstars download) :
