MetaQuotes continues to roll out vaguely described updates to its "no longer supported" MetaTrader 4 platform. They released MT4 Build 1420 yesterday and it should already be available through your broker's update system. As always, being an MT4 update, it fixes some unknown security issues, errors, and stability problems.
Warning: Please be aware that traders report some old .ex4 files (especially expert advisors) fail to load in MT4 Build 1420. Most likely, their recompilation would be required. If you don't have source files for your important .ex4 programs, it's probably worth to postpone the update.
The official announcement page for this update can be found here:
