batch-request 3.1.2

I just released version 3.1.2 of lemric/batch-request, a PHP library that lets you send a single HTTP request containing multiple API calls, with independent operations processed in parallel.

Here is what is new and improved in this release:

RFC 7807 error handling: Failed sub-requests now return Content-Type: application/problem+json, making it easy for HTTP clients to distinguish errors from successful responses. The error envelope stays backward compatible while supporting all standard RFC 7807 fields.

Mixed content type support: A single batch can now freely mix sub-requests returning different media types, including JSON, HTML, XML, SVG, PDF, PNG, binary streams, and 204 No Content. Binary payloads are automatically base64-encoded and marked with a body_encoding field so clients know how to decode them.

Symfony Profiler integration: The package now ships a dedicated BatchRequestBundle for Symfony 6.4 through 8.x. It adds a Batch Request panel to the WebProfiler toolbar showing per-transaction details: method, URI, HTTP status, duration, memory delta, request and response headers, and the full response body. The traceable executor is also safe for long-running workers like FrankenPHP, Swoole, and RoadRunner.

Flexible configuration: A new lemric_batch_request.yaml config allows you to set max batch size, max concurrency, content length limits, header whitelists, rate limiter binding, and profiler toggle, all without touching service definitions.

Laravel support improvements: The Laravel bridge received updates aligned with the new facade architecture and service provider structure.

Requires PHP 8.2 and supports Symfony 6.4/7.x/8.x and Laravel 10/11.
