v0.10.0a2

Breaking Changes

• Drop support for Python 3.10, which reaches end of life in October 2026. Reflex now requires Python 3.11 or newer. (#7449)

Bug Fixes

• AppHarness now forgets the states of every module of the app's package when it stops, not only those of the app module, so a state defined elsewhere in the app (for example one using rx.dynamic) no longer breaks the next app started in the same test process. (#7359)
• Deliver changes to client-storage and other state vars made by computed vars during hydration to the browser. (#7460)
• Prevent hydration from persisting client-storage defaults. (#7460)
• Configure per-component defaults in ComponentState.get_component with assignments such as cls.count = 10. Reset restores the last configured default. Defaults are no longer part of the saved-state schema, so changing one keeps state saved by this release or later loadable. Browser storage vars keep their storage settings when a factory is assigned, and declared factories are honored when compiled and reset. (#7461)
• Assigning a double-underscore private attribute on a state (self.__counter = 1) from a mixin, a base, or a class whose name starts with an underscore no longer raises SetUndefinedStateVarError in dev mode. Private names not explicitly declared with rx.field() are plain Python attributes: vars do not update in response to them. (#7465)

Miscellaneous

• Allow wrapt 2.4 and 2.5. (#7424)
• Require sibling package versions from the Python 3.11 release train. (#7464)
