Reflex

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 https://github.com/reflex-dev/reflex/pull/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 https://github.com/reflex-dev/reflex/pull/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 https://github.com/reflex-dev/reflex/pull/4518

Improvements

More Efficient Database Connection Pooling
