Fixes
-
support React 19 by moving Provider defaults out of defaultProps - react 19 removed defaultProps for function components, which silently disabled auth initialization (initializeAuth defaulted via defaultProps)
for consumers not passing it explicitly -
target exactly which files to publish - the denylist approach was already leaking codecov.yml, .codeclimate.yml, CONTRIBUTING.md, and a stale dist/ into the tarball, and would have shipped any future additions (CLAUDE.md, .claude/, etc.) by default.
