There's no changelog, but it seems to fix a few crashes/bugs.
BSG seems to be updating this post from time to time, he might add a changelog later.
This is yet another apk from him with the same name (MGC_5.3.015.apk), so it was renamed to "MGC_5.3.015_4.apk".
- For GCam support, a Telegram group and channel are available.
- Say "thanks" to BSG for his work by sending him a donation: Yandex Money.
