• Align Firehose package tags with the pub.flutter-io.cn server_native-v{{version}} policy.

• Correct README protocol defaults, Dart API-DL transport descriptions, TLS and platform limits, and compatibility scope; remove obsolete Rust benchmark tables.

• Reuse the checksum-pinned 1.0.0-dev native binaries; no runtime changes.

• Generate release metadata from the configured binary tag so documentation-only package updates can retain their verified prebuilts.

Breaking changes #

• Zig 0.16 replaces the Rust runtime, Cargo toolchain, bindings, and artifacts.
• Supported native targets are Linux x64 and ARM64. This prerelease does not support the other platforms previously served by Rust.
• Requires Dart 3.13 or later. The public Dart HTTP server API is retained; legacy Rust backend selectors no longer select a runtime.

Protocols and compatibility #

• Added Zig HTTP/1.1 and TLS, HTTP/2 through nghttp2, and HTTP/3 through ngtcp2/nghttp3 with BoringSSL.
• Added incremental responses, keep-alive and pipelining, chunked bodies, TCP/Unix bridge modes, and direct Dart-port request handling.
• Preserved WebSocket upgrades and detached sockets across HTTP server close; bounded tunnel frames prevent byte loss with slow readers.
• Fixed truncated-response handling, TLS handshake isolation, and shutdown without an active request listener.
• Added HTTP/3 streaming, cancellation, flow control, graceful shutdown, and independent curl/aioquic interoperability coverage.
• Expanded dart:io, Shelf, and Relic 2 RC compatibility tests and wire fixtures.

Runtime and distribution #

• Added Firehose PR release validation and tag-triggered pub.flutter-io.cn publishing.

• Added bounded native queues, Dart API-DL wake notifications, and parking mutexes to avoid spinning under worker contention.

• Added verified Linux x64/ARM64 prebuilt release packaging with archive and library checksums, architecture validation, and a Zig source-build fallback.

• Moved package and binary-release metadata to the standalone server_native repository. Updated the setup utility to use the pinned verified manifest.

• Port tokenized request-start and header encoding to the Zig bridge protocol.

• Add the first Zig bridge-protocol parity layer with bounded frame encoding and decoding.

• Fixed native-callback direct frame handling in server_boot_proxy_direct.dart to avoid routing single-frame direct requests through the stream path, improving shelf compatibility stability under repeated request/response cycles.

• Added loopback bind retry handling for transient dual-stack ephemeral EADDRINUSE collisions, including wrapped native bind error detection.

• Updated HTTP/3 integration CI to install a pinned static curl build with guaranteed HTTP/3 support and checksum verification, so HTTP/3 integration tests run deterministically instead of being skipped based on runner curl capabilities.

• Fixed native shelf/relic compatibility for empty Connection header values by preserving empty connection header semantics across sanitize/rewrite/bridge encoding paths.

• Fixed native response contentLength close parity for HEAD, 1xx, 204, and 304 responses to match dart:io behavior.

• Added Rust and Dart regression coverage for empty/sanitized connection header preservation and HEAD content-length close behavior.

• Fixed native callback websocket tunnel stability by switching direct frame polling to a non-blocking fair scheduling loop.
• Added and expanded framework compatibility tooling (tool/framework_compat.dart) and deterministic patch sets for shelf and relic.
• Added CI workflow for framework compatibility coverage (.github/workflows/server_native_framework_compat.yml).
• Updated framework compatibility CI to build the local Rust native library before native-mode runs (instead of relying on downloaded prebuilts).
• Fixed framework compatibility CI artifact upload path so per-matrix JSON reports are always collected.
• Added relic A/B parity regression coverage for transfer-encoding handling, websocket ping interval behavior, graceful close, malformed host/url handling, and connectionsInfo.
• Added native transfer-encoding regression tests to lock behavior across lenient GET/HEAD and chunked edge-cases.
• Improved HttpRequest URI reconstruction and malformed-target handling parity with dart:io.
• Improved bridge-mode HttpRequest/HttpResponse compatibility across default headers, streaming start timing, and detach/hijack flows.
• Stabilized native callback detach/hijack handling and direct stream lifecycle cleanup under shutdown and tunnel-close races.

• Split large Dart runtime files into focused modules for server boot, proxy runtime, direct path, and bridge codec/request/response layers.
• Added extensive Dart and Rust internal documentation across hot-path runtime code and protocol helpers.
• Fixed NativeMultiServer.bind to consistently forward the http2 flag.
• Fixed NativeHttpServer.connectionsInfo() tracking in native callback mode by wiring request/socket lifecycle counters on the direct callback path.
• Added callback-free direct frame polling mode for native direct transport to avoid Rust->Dart callback teardown races.
• Fixed NativeHttpServer.close(force: true) shutdown hangs by cancelling active Rust connection tasks during shutdown.
• Added explicit regression tests for NativeHttpServer.close(force: true) in both bridge and native-callback modes.
• Reduced runtime log noise by silencing expected shutdown cancellation/tunnel teardown messages by default.
• Added server_native.verbose_logs toggle for opt-in verbose runtime diagnostics (including non-TLS HTTP/3 downgrade notices).
• Split native binary publishing to dedicated prebuilt release tags (server-native-prebuilt-v*) independent from Dart package tags.
• Updated server_native:setup to resolve latest prebuilt-specific release tags instead of generic repository latest release.
• Added generated prebuilt release metadata (lib/src/generated/prebuilt_release.g.dart) sourced from pubspec.yaml version.
• Updated hooks/setup to use versioned prebuilt paths (.dart_tool/server_native/prebuilt/<tag>/<platform>/) with legacy path fallback.
• Updated prebuilt CI workflow to auto-derive release tags from package version when no tag input is provided.
• Removed save_to_repo prebuilt commit path from CI to avoid drift from release source-of-truth.
• Updated hook prebuilt lookup priority to prefer downloaded versioned prebuilts over packaged fallback binaries.
• Switched setup/hook cache path from .prebuilt/... to .dart_tool/server_native/prebuilt/....
• Removed checked-in native prebuilt binaries from the repository; GitHub binary releases are now the source-of-truth.
• Added hook-level prebuilt auto-download from versioned GitHub release assets when no local prebuilt is found.
• Regenerated native/bindings.h and lib/src/ffi.g.dart to keep generated FFI artifacts in sync with native source updates.

• Reduced packaged prebuilt binary sizes for pub.flutter-io.cn publish limits.
• Updated prebuilt CI flow to strip artifacts and skip ios-sim-x64 in repo prebuilts.

• Initial release of server_native.
• Added NativeHttpServer with HttpServer-style bind/loopback APIs.
• Added multi-bind helpers: NativeMultiServer and NativeServerBind.
• Added native callback and direct-request server modes.
• Added framework and transport benchmark harnesses and documentation.
