v0.6.7

Deprecations

• app.add_custom_404_page is deprecated -- use app.add_page(..., route="/404") instead.
• external prop of rx.redirect is renamed to is_external for consistency.
  • Unify is_external prop in rx.redirect and rx.link by @ElijahAhianyo in #4389

New Features

async_db_url and rx.asession

Builtin support for async database operations using sqlmodel. Proper usage requires the following:

1. Install greenlet for sqlalchemy to use async operations.
2. Install an appropriate async-capable database driver (aiosqlite, pyscopg)
3. Set ASYNC_DB_URL in the environment that references the async db driver. This should point to the same database as specified in DB_URL, which should still be set for handling alembic migrations and for use in computed vars, etc.
4. Use async with rx.asession() as asession -- await most operations on the asession.

Async DB operations are preferred in event handlers to avoid blocking other users on the server.

Var Operations for datetime values

• add datetime var comparison operations by @Lendemor in #4406

[Wrapping React] new deps and position fields in VarData

This allows for customization and control of where hooks are rendered relative to other hooks and memoized event handlers. Deps allows for specification of vars that memoized event handlers depend on.

• add deps and position field in VarData by @Lendemor in #4518
