v2.0.6

Wife and kids are out of house so I had time to do many rounds of code review. Some minor security tweaks and translation fixes.

• Implemented few security recommendations
• Added current version of application to title
• Fixes for hardcoded messages in server backend component. I focused way too much on frontend in last few days. Now server side messages are fully translatable.

Full Changelog: v2.0.5...v2.0.6
