## 0.5.0

Published Oct 2, 2022

- Performance improvements:
- Interpreter is now 5x-20x faster on code written in Squiggle
- SampleSet to PointSet conversions are 2x faster
- cdf function on SampleSets is 30x faster
- overall speedup is about 2x on average on real code written in Squiggle

- 50% smaller bundle size for @quri/squiggle-lang; 20% smaller bundle size for @quri/squiggle-components.

### Breaking changes

Some rarely used math functions got removed or moved to the `Math`

namespace.

For example, `cos(x)`

is now `Math.cos(x)`

, and `atanh(x)`

doesn't exist.

If your code is now failing with `<function> is not defined`

for anything from this list, try adding `Math.`

prefix first, and then complain on Github issues.
