PSL 6.3.0

This release adds Type\numeric(), fixes HTTP header validation, and updates the documentation site.

Type System

• Type\numeric(): A new type for integers, floats, and numeric strings. It preserves the input’s type, so numeric strings remain strings. Coercion also accepts Stringable objects whose string value is numeric. (by @gsteel in [#793])

  :::php use Psl\Type;

  Type\numeric()->assert(42); // 42 Type\numeric()->assert(3.14); // 3.14 Type\numeric()->assert('1.23'); // '1.23'

Fixes

• HTTP\Client: Validates all Transfer-Encoding response fields, including repeated fields. Invalid or unsupported transfer codings now raise a ProtocolException instead of falling back to Content-Length. Valid chunked responses still take precedence over Content-Length. (by @azjezz in [#806])
• HTTP\Client and H2: Reject conflicting Content-Length fields in HTTP/1.1 responses and HTTP/2 headers while accepting identical duplicates. (by @azjezz in [#800])
• Dict\diff(): Corrects the PHPDoc value type bound to scalar|null|resource|Stringable, matching the string conversion used for comparisons. Runtime behavior is unchanged. (by @azjezz in [#796])

Documentation

• Static pages: The documentation site now serves pre-rendered HTML pages. (by @veewee in [#782])
• Section permalinks: Added direct links to section headings (by @erikgaal in [#784]), with GitHub-style anchors on hover (by @veewee in [#785]).
• Deployment: Documentation builds now preserve the custom domain across deployments and rebuilds. (by @veewee in [#783])
• Iter\last_key_opt(): Corrected the description to say that the function returns the last key. (by @klifoth in [#803])
• Compression guide: Fixed heading formatting. (by @94noni in [#801])
