# MetaTrader 5 platform build 3091: Improvements

## Improved MQL5 program debugger

22 October 2021

### Terminal

1. Fixed opening of an empty page when purchasing MQL5 services. Now operation results are immediately displayed to the user.
2. Fixed excessive compression of document images which users upload when [requesting real accounts](https://www.metatrader5.com/en/terminal/help/startworking/acc_open#real). This has improved the quality of automatic KYC checks and has facilitated the entire account opening procedure.
3. Fixed operation of graphs which are opened upon testing completion.

### MQL5

1. Added support for SQLite 3.36.0.

### MetaEditor

1. Added background highlighting for matching brackets. The option can be enabled via MetaEditor's [general settings](https://www.metatrader5.com/en/metaeditor/help/beginning/settings#common).
2. Improved MQL5 program [debugger](https://www.metatrader5.com/en/metaeditor/help/development/debug).

Fixed errors reported in crash logs.
