# GraalVM Changelog

## `tip`
### Graal
* New methods for querying memory usage of individual objects and object graphs in Graal API (MetaAccessProvider#getMemorySize, MetaUtil#getMemorySizeRecursive).
* New (tested) invariant that equality comparisons for JavaType/JavaMethod/JavaField values use .equals() instead of '=='.
* Made graph caching compilation-local.

### Truffle
* New API TruffleRuntime#createCallNode to create call nodes and to give the runtime system control over its implementation.
* New API RootNode#getCachedCallNodes to get a weak set of CallNodes that have registered to call the RootNode.
* New API to split the AST of a call-site context sensitively. CallNode#split, CallNode#isSplittable, CallNode#getSplitCallTarget, CallNode#getCurrentCallTarget, RootNode#isSplittable, RootNode#split.
* New API to inline a call-site into the call-graph. CallNode#isInlinable, CallNode#inline, CallNode#isInlined.
* New API for the runtime environment to register CallTargets as caller to the RootNode. CallNode#registerCallTarget.
* Improved API for counting nodes in Truffle ASTS. NodeUtil#countNodes can be used with a NodeFilter filter Nodes.
* New API to declare the cost of a Node for use in runtime environment specific heuristics. See NodeCost, Node#getCost() and NodeInfo#cost().
* Removed old API for NodeInfo#Kind and NodeInfo#kind(). As a replacement the new Node cost API can be used.
