I'm excited to announce the latest version of TransformersPHP, packed with new features, improvements, and bug fixes. This release brings powerful enhancements to your machine-learning-driven PHP applications, enabling more efficient and versatile operations.

- **New Pipeline: Audio Classification** - Easily classify audio clips with a pre-trained model.

```php

$classifier = pipeline('audio-classification', 'Xenova/ast-finetuned-audioset-10-10-0.4593');

$audioUrl = __DIR__ . '/../sounds/cat_meow.wav';

$output = $classifier($audioUrl);

// [

// [

// "label" => "Meow"

// "score" => 0.6109990477562

// ]

// ]

```

- **New Pipeline: Automatic Speech Recognition (ASR)** - Supports models like `wav2vec` and `whisper` for transcribing speech to text. If a specific model is not officially supported, please open an issue with a feature request.

- Example:

```php

$transcriber = pipeline('asr', 'Xenova/whisper-tiny.en');

$audioUrl = __DIR__ . '/../sounds/preamble.wav';

$output = $transcriber($audioUrl, maxNewTokens: 256);

// [

// "text" => "We, the people of the United States, ..."

// ]

```

### Enhancements

- **Shared Libraries Dependencies:** - A revamped workflow for downloading shared libraries dependencies ensures they are versioned correctly, reducing download sizes. These binaries are now thoroughly tested on Apple Silicon, Intel Macs, Linux x86_64, Linux aarch64, and Windows platforms.

- **`Transformers::setup` Simplified** - `Transformers::setup()` is now optional. Default settings are automatically applied if not called. The` apply()` method is no longer necessary, but still available for backward compatibility.

- **Immutable Image Utility** - The Image utility class is now immutable. Each operation returns a new instance, allowing for method chaining and a more predictable workflow.

```php

$image = Image::read($url);

$resizedImage = $image->resize(100, 100);

// $image remains unchanged

```

- **New Tensor Operations** - New operations were added: `copyTo`, `log`, `exp`, `pow`, `sum`, `reciprocal`, `stdMean`. Additionally, overall performance improvements have been made to Tensor operations.

- **TextStreamer Improvements** - TextStreamer now prints to stdout by default. You can override this behavior using the `onStream(callable $callback)` method. Consequently, the `StdoutStreamer` class is now obsolete.

- **VIPS PHP Driver Update** - The VIPS PHP driver is no longer bundled by default in `composer.json`. Detailed documentation is provided for installing the Vips PHP driver and setting up Vips on your machine.

- **ONNX Runtime Upgrade** - Upgraded to version 1.19.0, bringing more performance and compatibility with newer models.

- Bug Fixes & Performance Improvements - Various bug fixes have been implemented to enhance stability and performance across the package.
