## 0.1.0

### Breaking Changes

* The recently added flow-state versions of `isBarrierIn`, `isBarrierOut`, `isSanitizerIn`, and `isSanitizerOut` in the data flow and taint tracking libraries have been removed.
* The `getURL` member-predicates of the `HTTP::Client::Request` and `HTTP::Client::Request::Range` classes from `Concepts.qll` have been renamed to `getAUrlPart`.

### Deprecated APIs

* `ConstantValue::getStringOrSymbol` and `ConstantValue::isStringOrSymbol`, which return/hold for all string-like values (strings, symbols, and regular expressions), have been renamed to `ConstantValue::getStringlikeValue` and `ConstantValue::isStringlikeValue`, respectively. The old names have been marked as `deprecated`.

### Minor Analysis Improvements

* Whereas `ConstantValue::getString()` previously returned both string and regular-expression values, it now returns only string values. The same applies to `ConstantValue::isString(value)`.
* Regular-expression values can now be accessed with the new predicates `ConstantValue::getRegExp()`, `ConstantValue::isRegExp(value)`, and `ConstantValue::isRegExpWithFlags(value, flags)`.
* The `ParseRegExp` and `RegExpTreeView` modules are now "internal" modules. Users should use `codeql.ruby.Regexp` instead.
