0.9.4

@quri/squiggle-lang (opens in a new tab)

Standard library:

• Added Spec.make function and @spec tag (#3113 (opens in a new tab))

• Added the basic try() function (#3137 (opens in a new tab))

• Added PointSet.support function and a new MixedSet.* namespace with several functions for working with 1-dimensional sets of points and segments (#3115 (opens in a new tab), #3151 (opens in a new tab))

• Added Danger.yTransform function (#3127 (opens in a new tab))

Bugfixes:

• Fixed the issue with very slightly negative KDE values because of floating point errors (#3114 (opens in a new tab))

• Fixed parsing of x = {|...|...} -> ... statements(#3136 (opens in a new tab))

Internals:

• Use a custom PRNG (aleaPRNG) and always require seed in environment (#3006 (opens in a new tab))

  • 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 (opens in a new tab))

• All Squiggle values are serializable (#3158 (opens in a new tab))

• Support pluggable runners, including the experimental webworker runner (#3158 (opens in a new tab))

• Simplified AST representation (#3136 (opens in a new tab))

• Disallow overrides of an internal function responsible for index lookups (#3135 (opens in a new tab))

@quri/squiggle-components (opens in a new tab)

Features:

• Stable seeds; re-runs of the same model with the same seed will always give the identical result (#3006 (opens in a new tab))

• Added Meta+PageUp/PageDown shortcuts to control the current viewer tab (#3055 (opens in a new tab))

• Added clickable gutter lines to focus on value variables (#2980 (opens in a new tab))

• Show export data and links in Viewer (#3056 (opens in a new tab))

• Support autorun={false} prop in <SquigglePlayground> component (#3119 (opens in a new tab))

Bugfixes:

• Fixed the regression where stacktrace locations weren't clickable

• Recognize != operators during highlighting (#3133 (opens in a new tab))

• Fixed the issue with persisting focus and collapse/expand state after errors (#3129 (opens in a new tab))

Experimental:

• WebWorker runner (#3158 (opens in a new tab))
