http://poster.themasoftware.com/faq.php?expand=faq507v.4.44 beta
- Added preview message support inside posts list edit post window with shortcut ALT+X.
- Added new right click option for status tables "Copy status".
- Added support for hCaptcha with Anti-Captcha service.
- Added new option in "CONFIG" -> on the left "Security processing threads". Higher value = more CPU and memory usage.
- Fixed Cloudflare issue. Note you must have "Firefox" installed for it to work now (latest version [77.0.1] preferred). You also must have "Microsoft Visual Studio redistributable runtime" installed as well [which you might already have] (check the official forum for more details and download links if needed).
- Fixed few posting problems.
- Moved PM related settings to "CONFIG" -> "PM".
- Other small improvements and fixes.
