Release Notes for 474

Improvements to Luau VM memory analysis tools including new Memory groups in the Developer Console

Fixed a bug causing type mismatch errors to be the reverse of what they should be in some scenarios.

As noticed in this post the range at which fog become opaque underwater is limited, which makes a very short limited range of visibility for places which have more distant content in their experiences underwater.

However, as places may have a designed use of alternative types of submersed liquid and the transparency control already exists in a range [0,1], a limit of further distance and still providing a useful grading for the slider control is updated and is expected to be a reasonable maximum for a foreseeable future.

As many places are tuned to the existing underwater transparency API control, this change is delivered first as a studio beta release where places can enable the beta feature and adapt to this API behavior change.

Consideration for Jerlov water types has been made where fog attenuation underwater is strongly wavelength dependent (color falloff with distance varies differently according to water types). However, these effects are reasonably sufficiently modelled with the existing water fog color API and more physical underwater atmosphere model is deferred to a future date.
