Most built-ins are encapsulated in core-js for preventing possible cases of breaking / observing the internal state by patching / deleting of them
- Avoid .call / .apply prototype methods that could be patched
- Avoid instanceof operator - implicit .prototype / @@hasInstance access that could be patched
- Avoid RegExp#test, String#match and some over methods - implicit .exec and RegExp well-known symbols access that could be patched
Clearing of Error stack from extra entries experimentally added to AggregateError, #996, in case lack of problems it will be extended to other cases
In engines with native Symbol support, new well-known symbols created with usage Symbol.for for ensuring the same keys in different realms, #998
Added a workaround of a BrowserFS NodeJS process polyfill bug that incorrectly reports V8 version that's used in some cases of core-js feature detection
Fixed normalization of message AggregateError argument
