## 0.2.2

No user-facing changes.

## 0.2.1

No user-facing changes.

## 0.2.0

### Breaking Changes

* The `edges` predicate contained in `PathGraph` now contains two additional columns for propagating model provenance information. This is primarily an internal change without any impact on any APIs, except for specialised queries making use of `MergePathGraph` in conjunction with custom `PathGraph` implementations. Such queries will need to be updated to reference the two new columns. This is expected to be very rare, as `MergePathGraph` is an advanced feature, but it is a breaking change for any such affected queries.

## 0.1.8

No user-facing changes.

## 0.1.7

No user-facing changes.

## 0.1.6

### Deprecated APIs

* The old configuration-class based data flow api has been deprecated. The configuration-module based api should be used instead. For details, see https://github.blog/changelog/2023-08-14-new-dataflow-api-for-writing-custom-codeql-queries/.

## 0.1.4

## 0.1.3

No user-facing changes.

## 0.1.2

### Bug Fixes

* The API for debugging flow using partial flow has changed slightly. Instead of using `module Partial = FlowExploration<limit/0>` and choosing between `Partial::partialFlow` and `Partial::partialFlowRev`, you now choose between `module Partial = FlowExplorationFwd<limit/0>` and `module Partial = FlowExplorationRev<limit/0>`, and then always use `Partial::partialFlow`.

## 0.1.1

No user-facing changes.

## 0.1.0

### Major Analysis Improvements

* Added support for type-based call edge pruning. This removes data flow call edges that are incompatible with the set of flow paths that reach it based on type information. This improves dispatch precision for constructs like lambdas, `Object.toString()` calls, and the visitor pattern. For now this is only enabled for Java and C#.

### Minor Analysis Improvements

* The `isBarrierIn` and `isBarrierOut` predicates in `DataFlow::StateConfigSig` now have overloaded variants that block a specific `FlowState`.

## 0.0.4

No user-facing changes.

## 0.0.3

### New Features

* The various inline flow test libraries have been consolidated as a shared library part in the dataflow qlpack.

### Minor Analysis Improvements

* The shared taint-tracking library is now part of the dataflow qlpack.

## 0.0.2

### Major Analysis Improvements

* Initial release. Adds a library to implement flow through captured variables that properly adheres to inter-procedural control flow.

## 0.0.1

### New Features

* The `StateConfigSig` signature now supports a unary `isSink` predicate that does not specify the `FlowState` for which the given node is a sink. Instead, any `FlowState` is considered a valid `FlowState` for such a sink.

### Minor Analysis Improvements

* Initial release. Moves the shared inter-procedural data-flow library into its own qlpack.
