3.2.0 (2021-08-09)

Compatibility Notes

This release contains no public API breakage. However, there are a few compatibility related notes:

• Due to usage of new runtime helpers, code generated by the template compiler in >= 3.2 will not be compatible with runtime < 3.2.

  This only affects cases where there is a version mismatch between the compiler and the runtime. The most common case is libraries that ship pre-compiled Vue components. If you are a library author and ship code pre-compiled by Vue >= 3.2, your library will be only compatible Vue >= 3.2.

• This release ships TypeScript typings that rely on Template Literal Types and requires TS >= 4.1.
