A new build of MetaTrader 5 platform was released by MetaQuotes yesterday on June 8 - Build 3800. You can now download it via the automatic update facility. The main addition is the Copilot support for MetaEditor. However, the new version adds a lot of changes and, unfortunately, may also introduce some incompatibilities with the old MQL5 code:
