v0.9.4

0.9.4

Standard library:

Added Spec.make function and @spec tag (#3113)
Added the basic try() function (#3137)
Added PointSet.support function and a new MixedSet.* namespace with several functions for working with 1-dimensional sets of points and segments (#3115, #3151)
Added Danger.yTransform function (#3127)

Bugfixes:

Fixed the issue with very slightly negative KDE values because of floating point errors (#3114)
Fixed parsing of x = {|...|...} -> ... statements(#3136)

Internals:

Use a custom PRNG (aleaPRNG) and always require seed in environment (#3006)
- Note that this can make some models up to 2x slower, because it's hard to beat the native Math.random; but we'll make up for it with other optimizations in future releases
Variable stack is array-based, with up to 50% better performance in synthetic tests (#3054)
All Squiggle values are serializable (#3158)
Support pluggable runners, including the experimental webworker runner (#3158)
Simplified AST representation (#3136)
Disallow overrides of an internal function responsible for index lookups (#3135)

Features:

Stable seeds; re-runs of the same model with the same seed will always give the identical result (#3006)
Added Meta+PageUp/PageDown shortcuts to control the current viewer tab (#3055)
Added clickable gutter lines to focus on value variables (#2980)
Show export data and links in Viewer (#3056)
Support autorun={false} prop in <SquigglePlayground> component (#3119)

Bugfixes:

Fixed the regression where stacktrace locations weren't clickable
Recognize != operators during highlighting (#3133)
Fixed the issue with persisting focus and collapse/expand state after errors (#3129)
Render negative values in pointsets correctly (#3126)
