I’m pleased to announce [Hyperbole 0.5](https://hackage-content.haskell.org/package/hyperbole-0.5.0/docs/Web-Hyperbole.html)!

Hyperbole enables you to write interactive HTML applications with type-safe serverside Haskell. It is inspired by HTMX, Elm, and Phoenix LiveView.

Improvements

- `trigger` actions in other views

- Javascript FFI

- Documents

- Websocket - ping keepalive

- New form fields: `radio`, `select`

- `Web.Hyperbole.Effect.OAuth2` - Authentication

- `Web.Hyperbole.Effect.GenRandom` - Simple random effect used by OAuth2

- Error handling, custom errors

- Examples

Breaking Changes / Improvements

- `Web.Atomic.CSS` overhauled, and is now opt-in. Use new `@` and `~` operators to apply attributes and styles

- `Web.Hyperbole.Data.Param` - unified param encoding for Forms, ViewId, ViewAction, Sessions, Queries

- `Web.Hyperbole.Data.Encoding` - encoding for ViewId, ViewAction

- `Web.Hyperbole.Data.URI` - Standardize on `Network.URI`, extra utilities to manage paths

- `trigger`: required refactor of `Page` type alias to support type-checking: `Eff es (Page '[])` is now `Page es '[]`
