0.1.0 (2025-03-18)

Initial release.

Unified API - gen_http module works with both HTTP/1.1 and HTTP/2 connections through a single interface. Protocol selection is automatic via ALPN for HTTPS, HTTP/1.1 for plain HTTP.
HTTP/1.1 state machine (gen_http_h1) - Request pipelining, keep-alive, chunked transfer encoding, body streaming for requests and responses.
HTTP/2 state machine (gen_http_h2) - Stream multiplexing, connection and stream level flow control, settings negotiation, GOAWAY handling, server push support. RFC 9113 compliant.
HPACK header compression (gen_http_parser_hpack) - Static and dynamic tables with Huffman coding. Pure data structure, no process state. RFC 7541 compliant.
Active and passive socket modes - Active mode delivers data as Erlang messages via stream/2. Passive mode uses blocking recv/3. Switch between them at any time with set_mode/2.
Structured error types - Errors are tagged as {transport_error, _}, {protocol_error, _}, or {application_error, _}. Use is_retriable_error/1 to decide whether to retry.
Connection metadata - put_private/3, get_private/2,3, delete_private/2 for attaching pool IDs, metrics, or tags to connections.
Transport abstraction - gen_http_transport behaviour with TCP (gen_http_tcp) and SSL/TLS (gen_http_ssl) implementations. TLS certificate verification enabled by default.
Zero dependencies - Only OTP stdlib (kernel, stdlib, crypto, public_key, ssl). Targets OTP 25+.
