Concerns about instability after the large MT5 update (as of late July 2026)

This update is important content that could significantly change how future trading tools are used, and we plan to explain it in detail again in the future.
On the other hand, because this is a major update right after its release, there have been reports of instability in some environments.
Current confirmed状況
Currently, reports from users around the world include the following:
- CPU usage becomes abnormally high
- Overall MT5 performance becomes sluggish

MetaQuotes has released several interim fixes in a short period to improve stability.
Versions are mixed, which is normal
Currently, depending on the environment,
- Build 6060
- Build 6061
- Build 6063
- Build 6070
