IDL 8.6.1 was released today[^1]. Some interesting new features:
* Conditional breakpoints from the Workbench
* Hexadecimal constants, e.g., `a = 0xFF3A`
* Fix for strings that begin with numerals being confused with the octal notation: `"123` is an octal value; `"123"` used to be a syntax error, but is now a valid string.
See the [release notes] for details.
