What's Changed

🌟 Most Notable

Dependencies have been updated. Please restart Obsidian after updating the plugin. Thank you.

🌟 Major safety and usability improvements for regular expressions (regex) searches

• / characters no longer need to be escaped (as \/) in regular expressions.
  • This fixes #2136 - that file paths in regular expressions were wrongly truncated.
• explain now explains regular expressions.
• It's easier to correct syntax errors in regexes, as error info is now displayed, such as:
  • SyntaxError: Invalid regular expression: /hello(/: Unterminated group
• The u unicode flag is now supported.
• Any invalid flags are reported now instead of ignored.
  • These are often a sign of a missing / at the end of the regex.
• Any problems with regex result in the following 'help' being displayed inside Tasks code blocks:
