Release Notes

actions/toolkit (@​actions/tool-cache)

v2.0.1

• Update to v2.0.1 of @actions/http-client #​1087

v2.0.0

• Update to v2.0.0 of @actions/http-client
• The type of the headers parameter in the exported function downloadTool has been narrowed from { [header: string]: any } to { [header: string]: number | string | string[] | undefined; } (that is, http.OutgoingHttpHeaders).
  This is strictly a compile-time change for TypeScript consumers. Previous attempts to use a header value of a type other than those now accepted would have resulted in an error at run time.

v1.7.2

• Update lockfileVersion to v2 in `package-lock.json #​1025
