Known Problems

The transitive move-file dependency requires node >= 10.17, while webpack is intended to be >= 10.13 compatible. This temporary increases the min node version for this beta release until we found a solution to that.
- Fixed, latest patch releases are >= 10.13 compatible

Features

Using module in an ESM no longer needs the whole namespace object
SideEffects flag can follow reexports that are partially dynamic or use a compat default
export * uses more exports info data for better exports
dynamic export * no longer flags the default export as maybe provided
allow module concatenation even when provided exports are unknown, but used exports are known
add promise external, which is like var but awaits the global value in a async module
add import external, which uses import() to load a native ESM
add output.importFunctionName to change the import() to something else, e.g. to a polyfill.
remove some unneeded dependencies
Module Federation
- removed scope shortcut object config for container plugins (BREAKING)
- add ability to pass advanced options to container plugins
- allow to expose an array of modules (similar to entry)
- allow to provide an array of remote locations (they act as fallback)
- await when a promise is returned by the external
- allow to expose an index module which is used when using the remote without subpath
- change exposed keys to be prefixed with ./ (BREAKING)
- automatically inferred keys do no longer omit leading non-word chars
- add version handling to shared modules (see #10960 for details, BREAKING)

export default no longer converts function declarations to expressions
inline external type can also provided when using an array external.
fixed a bug in snapshotting that caused changes to be ignored during watching
add missing dependency for correct typings
Persistent Caching
- DllPlugin related classes are now serializable
- Dates are serializable
