Non-breaking changes:

- Add number of native and detached contexts to HeapStatistics
- Add support to produce code cache
- Add ScriptCompiler::OPTION_EAGER_COMPILE option
- Add support for integer-<strings for ObjectValue::GetOwnPropertyNames and `ObjectValue::GetPropertyNames
- Add {Template,ObjectValue}:setLazyDataProperty() method
0.2.1 This release brings stability and improvements. It contains some minor BC-breaking changes which should not affect general public. See full change log below for details


BC-breaking changes:

- require libv8 >= 6.4.6;
- remove UnboundScript::kNoScriptId const and return null in getId() on no data
- change ScriptCompiler::cachedDataVersionTag(): int method name and return type to be ScriptCompiler::getCachedDataVersionTag(): float;
- remove StartupData::getRawSize() method;

Non-breaking changes:

- fix segfault when invalid startup data passed to isolate;
- fix external exception lost when it has refcount 1;
- change script compiler version tag generation to take into account changes to extension internals;
- add CallbackInfoInterface;
- add support for ScriptCompiler::kProduceFullCodeCache;
- add {Isolate,Context}::within() as optimization solution;
- add StartupData::isRejected();
- add docs skeleton.
0.2.0 This release introduces many major changes to public API and breaks BC for the sake of more solid and stable API in a further versions.

Maintaining this project takes significant amount of time and efforts.
