Changes:

• Customizable digit group size and separator
• Option to enable/disable check for new versions
• Optional compact variant of parsed expression in history
• Highlight unmatched parenthesis (with red color)
• New default adaptive calculate-as-you-type delay (without delay in most cases)
• Improve decision to not do calculate-as-you-type or not show result of it
• "Approximation" caption changed to "Approximation and Fractions"
• New functions: reshape(), circshift(), replacePart()
• Functions mergevectors() and area() renamed to slice() and part()
• v[i, ...]=... syntax for assignment of part of matrix/vector variable
• Improve language handling for functions, units, and variables
• Limit the range of supported arguments in bessely, besselj, binomial, and igamma functions (to avoid segfault and very slow unabortable calculations)
• Do not try to calculate exact result with automatic approximation for expressions with iterative functions
• Fix handling of single quotation marks
• Minor bug fixes and feature enhancements
