What's New in the Latest Version 1.16.0

Last updated on Apr 3, 2023
Old Versions
• A big change to how text highlight logic works. It should not provide much better performance and reliability.
• Capture group coloring used to start with red, which was too harsh, it is now moved towards the end of the list of colors.
• Removed the "Created" message which appears on screen when a new regex is added.
• Added a "Select all" button for the test text.
• Fixed an issue where some text fields would be too "smart" and change characters such as `...` to `…` or `"` to `“`.
• Removed old third-party frameworks and switched to native code, which makes the app size smaller and improves performance.
