+- [`f8053e65`](https://github.com/tauri-apps/plugins-workspace/commit/f8053e659e4ccd85c1f52833411ff8417cbc5e69) ([#3527](https://github.com/tauri-apps/plugins-workspace/pull/3527) by [@Legend-Master](https://github.com/tauri-apps/plugins-workspace/../../Legend-Master)) Documented Cargo feature flags in each plugin's crate-level documentation.
+
+## \[2.4.2]
+
+### bug
+
+- [`66a75ece`](https://github.com/tauri-apps/plugins-workspace/commit/66a75ece27ee2f4e7364ef9ddc8db6cbeeb56919) ([#3124](https://github.com/tauri-apps/plugins-workspace/pull/3124) by [@FabianLars](https://github.com/tauri-apps/plugins-workspace/../../FabianLars)) The WebSocket plugin will now install the default crypto provider if needed, preventing panics on WSS connections.
+
+## \[2.4.1]
+
+- [`93426f85`](https://github.com/tauri-apps/plugins-workspace/commit/93426f85120f49beb9f40222bff45185a32d54a9) Fixed an issue that caused docs.rs builds to fail. No user facing changes.
+
+## \[2.4.0]
+
+- [`f209b2f2`](https://github.com/tauri-apps/plugins-workspace/commit/f209b2f23cb29133c97ad5961fb46ef794dbe063) ([#2804](https://github.com/tauri-apps/plugins-workspace/pull/2804) by [@renovate](https://github.com/tauri-apps/plugins-workspace/../../renovate)) Updated tauri to 2.6
+
+## \[2.3.1]
+
+- [`f634e524`](https://github.com/tauri-apps/plugins-workspace/commit/f634e5248ebe428f8305a59f74c13fc15147fb8e) This is an "empty" release to update the plugins' source files on crates.io and docs.rs. This should fix docs.rs build failures for projects using tauri plugins as dependencies.
+
+## \[2.3.0]
+
+- [`78acfa45`](https://github.com/tauri-apps/plugins-workspace/commit/78acfa456f343c0af5fbf35660802d14ff7a5eca) ([#2027](https://github.com/tauri-apps/plugins-workspace/pull/2027) by [@twlite](https://github.com/tauri-apps/plugins-workspace/../../twlite)) `addListener` now returns a cleanup function instead of `void` to remove the listener.
+
+## \[2.2.1]
+
+- [`05cca602`](https://github.com/tauri-apps/plugins-workspace/commit/05cca602d927c30014d3892438ca28d99bc4e1d3) ([#2210](https://github.com/tauri-apps/plugins-workspace/pull/2210) by [@renovate](https://github.com/tauri-apps/plugins-workspace/../../renovate)) **Breaking change:** Updated tokio_tungstenite to `0.26`. This may be a breaking change if you use the `tls_connector` Builder method in Rust.
+  **Breaking change:** Removed the accidental `ConnectionConfig` struct re-export (in rust). This should not affect anyone since the Config was not used in any public API.
+
+## \[2.2.0]
+
+- [`3a79266b`](https://github.com/tauri-apps/plugins-workspace/commit/3a79266b8cf96a55b1ae6339d725567d45a44b1d) ([#2173](https://github.com/tauri-apps/plugins-workspace/pull/2173) by [@FabianLars](https://github.com/tauri-apps/plugins-workspace/../../FabianLars)) Bumped all plugins to `v2.2.0`.

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+      negligent acts) or agreed to in writing, shall any Contributor be

+
+Open a WebSocket connection using a Rust client in JS.
+
+| Platform | Supported |
+| -------- | --------- |
+| Linux    | ✓         |
+| Windows  | ✓         |
+| macOS    | ✓         |
+| Android  | ✓         |
+| iOS      | ✓         |
+
+## Install
+
+_This plugin requires a Rust version of at least **1.77.2**_
+
+There are three general methods of installation that we can recommend.
+
+1. Use crates.io and npm (easiest, and requires you to trust that our publishing pipeline worked)
+2. Pull sources directly from Github using git tags / revision hashes (most secure)
+3. Git submodule install this repo in your tauri project and then use file protocol to ingest the source (most secure, but inconvenient to use)
+
+Install the Core plugin by adding the following to your `Cargo.toml` file:
+
+`src-tauri/Cargo.toml`
+
+```toml
+[dependencies]
+tauri-plugin-websocket = "2.0.0"
+# alternatively with Git:
+tauri-plugin-websocket = { git = "https://github.com/tauri-apps/plugins-workspace", branch = "v2" }
+```
+
+You can install the JavaScript Guest bindings using your preferred JavaScript package manager:
+
+```sh
+pnpm add @tauri-apps/plugin-websocket
+# or
+npm add @tauri-apps/plugin-websocket
+# or
+yarn add @tauri-apps/plugin-websocket
+```
+
+## Usage
+
+First you need to register the core plugin with Tauri:
+
+`src-tauri/src/lib.rs`
+
+```rust
+fn main() {
+    tauri::Builder::default()
+        .plugin(tauri_plugin_websocket::init())
+        .run(tauri::generate_context!())
+        .expect("error while running tauri application");
+}
+```
+
+Afterwards all the plugin's APIs are available through the JavaScript guest bindings:
+
+```javascript
+import WebSocket from '@tauri-apps/plugin-websocket'
+
+const ws = await WebSocket.connect('wss://example.com')
+
+await ws.send('Hello World')
+
+await ws.disconnect()
+```

+//! Open a WebSocket connection using a Rust client in JS.

+//! ## Cargo features
+//!
+//! - **rustls-tls** *(enabled by default)*: Enables TLS functionality provided by `rustls` with WebPKI roots.
+//! - **rustls-tls-native-roots**: Enables TLS functionality provided by `rustls` with the platform's native certificate roots.
+//! - **native-tls**: Enables TLS functionality provided by `native-tls`.
+//! - **native-tls-vendored**: Enables the `vendored` feature of `native-tls`.
+//!
+//! At least one TLS feature is required for `wss://`; plain `ws://` works without one.
