      • Version: 1.7 (2025‑12‑25) by Edmond [HT]
      • Goal: Add a standard concurrency model to PHP that lets existing synchronous code run in coroutines with minimal changes, without breaking current functions or extensions.
      • Key features:
      • New Async namespace with core functions: spawn(), await(), suspend(), current_coroutine(), shutdown(), get_coroutines().
      • Async\Coroutine class implements Completable: lifecycle methods (isRunning(), isSuspended(), etc.), result/exception retrieval, cancellation support.
      • Awaitable and Completable interfaces for awaitable objects.
      • Root‑namespace Cancellation exception (extends Throwable).
      • Graceful shutdown and deadlock detection mechanisms.
      • Fiber integration via an extended Fiber class exposing the current coroutine.
      • Compatibility: No changes to existing PHP functions or extensions; only new root namespace class may conflict with userland code.
      • Status: Under discussion on PHP RFC index.
      • RFC: TLS Session Resumption Support for Streams (Version 0.1, 2025‑10‑23)
      • Goal: Expose OpenSSL session management APIs via stream context options so PHP developers can cache and reuse TLS sessions on both client and server sides.
      • Key Features:
      • Client‑side session_data and session_new_cb for explicit resumption.
      • Server‑side options: session_cache, session_cache_size, session_timeout, session_context_id, session_get_cb, session_remove_cb.
      • TLS 1.3 ticket control with num_tickets.
      • Impact:
      • No backward‑incompatible changes; all new options are optional.
      • Benefits for HTTP clients, async frameworks, microservices via reduced handshake latency.
      • Implementation Status: PR https://github.com/php/php-src/pull/20296 under discussion (expected in PHP 8.5).
      • RFC: mysqli_quote_string
      • New Feature: Adds mysqli::quote_string() (and a procedural helper) to escape strings and automatically wrap them in single quotes.
      • Purpose: Close remaining SQL injection loophole in manual escaping, mirroring PDO’s PDO::quote().
      • Version Target: PHP 8.6
      • Status: Under Discussion; implementation pull request #20729 on GitHub.
      • RFC Title: Stringable Enums
      • Version: 0.1 (released 2025‑11‑07)
      • Proposal: Allow __toString() magic method on PHP enums, automatically adding the Stringable interface when present.
      • Status: Under Discussion; pull request #20415 merged into PHP 8.6.
      • Impact: Enables direct string conversion of enum cases; removes existing error and updates static analysis tools to stop flagging __toString() on enums.
      • Examples Provided: Both unit and backed enums with custom __toString() implementations.
      • Backward Compatibility: No changes, only removal of the restriction.
      • Future Scope: Potentially extend other magic methods to enums in later RFCs.
