Another week, another release. Happy Halloween! 🎃

Require

• Integrate support for .config.luau files into Luau.Require as part of the Luau-syntax configuration files RFC.
  • is_config_present has been replaced with get_config_status.
  • get_luau_config_timeout has been added to configure extraction timeouts at runtime.
• Enable support for .config.luau files in luau and luau-analyze.
• Merge the Luau.RequireNavigator static library into Luau.Require.

Analysis

• Add fuel-based limits for normalization: normalization will now take a set number of steps (the "fuel") and stop when we hit a certain number of steps ("run out of fuel"). This is in lieu of trying to check static limits on the size of its inputs. This may result in seeing more "code too complex" errors but should dramatically reduce the number of cases where Luau becomes unresponsive and uses several gigabytes of memory. We plan to tune this limit over time to find the right balance between responsiveness and completeness.
• Fix a case where refining a variable with the type any would cause it to become unknown instead due to normalization not preserving any in the top type position.
• Improve the wording of type errors in the new non-strict mode.
• Fix #1910.
• Fix #2065.
• Fix #1483.
• Fix #2018.

Miscellaneous

• Introduce Luau::overloaded to facilitate interacting with Luau::Variant.
• Add type checking support to the Luau demo!
