A controller declaration now owns request parsing,\nvalidation, typed access, response validation, content negotiation, and\nOpenAPI 3.1 output. The release also brings the optimized router and request\npath onto the V2 release line.\n\n## Upgrade compatibility comes first\n\nThe existing `params.validation` API still compiles and runs. It is deprecated\nso new work can use executable controller schemas, but upgrading to beta.5 does\nnot require rewriting every controller. Applications can update Amber, run\ntheir existing tests, and then migrate one action at a time.\n\nAmber does not plan to remove the deprecated validator before a later V2 minor\nsuch as 2.5. The exact removal release will be announced separately.\n\n## Executable request and response contracts\n\n- `schema :action, SchemaClass` enforces the declared request before the action\n  runs.\n- `validated_as(SchemaClass)` exposes request-local typed values without\n  constructing and validating a second schema object.\n- Request fields can come from bodies, paths, query strings, headers, and\n  cookies.\n- `response_schema` verifies the declared status, content type, and response\n  shape before delivery.\n- OpenAPI 3.1 operations are generated from the same contracts the application\n  executes.\n- Server-rendered controllers can override the schema-failure hook to return an\n  ECR form with field errors and the correct 400, 415, or 422 status.\n\n## JSON, CBOR, and authenticated COSE\n\nAmber now supports JSON, XML, URL-encoded forms, multipart forms, and bounded\nCBOR request parsing. COSE Encrypt0 adds authenticated ChaCha20-Poly1305\nencryption in both directions: Amber decrypts and authenticates the inbound\nrequest, applies its schema, and can authenticate and encrypt the response with\na fresh nonce.\n\nThe request boundary fails explicitly for malformed documents, unsupported\nmedia, invalid values, unacceptable response formats, invalid declared\nresponses, and temporarily unavailable encryption configuration.\n\n## Measured performance\n\nThe release candidate was tested on a DigitalOcean Basic one-shared-vCPU,\n512-MB-class target with a separate load generator, 16 keep-alive connections,\nand seven rotating 15-second repetitions per scenario:\n\n| Complete HTTP request path | Median requests/second |\n|---|---:|\n| Generic JSON decode | 20,728 |\n| Schema-validated JSON | 19,488 |\n| Schema-validated CBOR | 21,742 |\n| Authenticated COSE request and response | 14,443 |\n\nAll 7,974,608 retained requests returned HTTP 200. This is a synthetic\nin-memory acknowledgement workload without a database, TLS termination,\nexternal services, or HTML rendering. It measures framework, codec, and schema\ncost under constrained hardware; it is not a capacity promise for an arbitrary\nproduction application.\n\nSee\n[`benchmarks/DIGITALOCEAN_SCHEMA_CONTRACT_ROUND27.md`](benchmarks/DIGITALOCEAN_SCHEMA_CONTRACT_ROUND27.md)\nfor the complete method, ranges, before-and-after comparison, and evidence\npaths.\n\n## Start a fresh web application\n\nAmber CLI 2.0.6 is the coordinated generator release for this beta:\n\n```bash\nbrew install amberframework/amber_cli/amber_cli\namber new pet_tracker --type web\ncd pet_tracker\nshards install\namber assets check\namber generate scaffold Pet name:string:required species:string:required adopted:bool\namber database migrate\ncrystal spec\namber watch\n```\n\nThe generated application uses ECR, Grant, SQLite, Micrate, local front-end\nassets, executable HTML form schemas, and Amber `2.0.0-beta.5`.\n\nSee the [beta installation guide](https://github.com/amberframework/amber/blob/v2.0.0-beta.5/docs/beta-installation.md),\n[migration guide](https://github.com/amberframework/amber/blob/v2.0.0-beta.5/docs/migration-guide.md),\nand [schema guide](https://github.com/amberframework/amber/blob/v2.0.0-beta.5/docs/guides/schema-api.md).\n","release_id":370077221,"release_title":"Amber 2.0.0-beta.5","release_url":"https://github.com/amberframework/amber/releases/tag/v2.0.0-beta.5","source_commit":"76954f0e2edc10d568e7ffcea3faa94b2aa476d2","tag_name":"v2.0.0-beta.5"},{"is_prerelease":true,"list_of_assets":[],"published_at":"2026-08-12T04:23:00Z","release_body":"Amber 2.0.0-beta.4 connects the V2 web runtime to the deterministic asset compiler and closes the fresh-application path across macOS, Linux, Linux ARM64, and Windows CI.\n\nThe `beta` label applies to the Amber 2.0 release train.

This release restores compatibility and ships the security and performance work that had been waiting in review.\n\n### Compatibility\n\n- **`Amber::Cluster.fork` no longer uses `Process.fork`** (#1399) — cluster workers are spawned with `Process.new` (same mechanism as v2). `process_count` / master-worker semantics unchanged. Verified: framework specs, `amber new` → build → serve, and cluster mode with 2 workers, on Crystal 1.20.3 and 1.21.0.\n- **ameba pinned to `1.7.0-dev`** in framework dev-dependencies and the generated app template (#1399, supersedes #1394 — thanks @botantony). ameba ≤ 1.6.4 fails to build on Crystal 1.21, which broke `shards install` for new apps.\n- New [`COMPATIBILITY.md`](https://github.com/amberframework/amber/blob/master/COMPATIBILITY.md) documents which Crystal versions build which Amber releases.\n- Declared Crystal requirement is now `>= 1.20.0, < 2.0` (previously `>= 1.0.0`, which overstated reality).\n\n### Security (thanks @renich)\n\n- **XSS**: exception messages are HTML-escaped in the default error response (#1385).\n- **Command injection**: `amber encrypt` no longer passes the editor command through a shell (#1388).\n- **DoS hardening**: `MessageVerifier` / `MessageEncryptor` reject malformed payloads with typed exceptions instead of raising `IndexError` (#1386).\n- **SecureHeaders pipe** (#1390): new apps get `X-Content-Type-Options`, `X-Frame-Options`, `X-XSS-Protection`, and `Referrer-Policy` out of the box, plugged **above** the Error pipe so 404/403 responses keep their headers; HSTS is opt-in (`SecureHeaders.new(hsts: true)`).\n\n### Performance\n\n- Router content-extension matching uses string ops + set lookup instead of regex alternation (#1387, #1391, thanks @renich).\n\n### CI / contributor experience\n\n- CircleCI (broken at the project level) replaced with GitHub Actions: spec matrix on Crystal 1.20.3 + latest, Linux + macOS.\n- Contributor review rubric, PR template, and local dev hooks (#1393).\n\n### Upgrade notes\n\n- If your app pins `amber` to `1.4.1` exactly (the default for apps generated by older CLIs), change it to `~> 1.5.0` in `shard.yml` to build on Crystal 1.21.\n- Existing apps do **not** get SecureHeaders automatically — it's wired in the new-app template.

CLI 2.0.7 helps coding agents such as Claude Code and Codex write Crystal that compiles the first time, in Amber V2 apps, plain Crystal apps, and Crystal shards.\n\n## Install or upgrade\n\n```bash\nHOMEBREW_NO_AUTO_UPDATE=1 brew install amberframework/amber_cli/amber_cli\namber --version\namber-lsp --version\n```\n\n## What's new\n\n- **`amber-lsp lookup 'Type.method'`** answers from your project's real code: its own source, every shard in `lib/`, and the Crystal standard library. It prints the signature, the resolved return type, where the method is defined, its doc comment, and notes from API cards. It falls back to stock `crystal` when `crystal-alpha` is not installed.\n- **`amber-lsp hint`** reads compiler output and prints the fix for known mistakes.\n- **`amber setup:agent`** connects Claude Code and Codex to `amber-lsp` in any Crystal project. It installs hooks that tell the agent to look methods up first, format each edited file, check Amber V2 rules in Amber apps, and build when the agent stops. Crystal edits are held back until `amber-lsp` is installed and checksum-verified.\n- **`amber doctor`** reports the same readiness checks, agent trust, and index freshness, with a fix for each failure.\n- **`amber-lsp --help`** documents every mode.\n- **API cards**: libraries ship notes and error hints in `.amber-lsp/api/*.yml`.

Fresh web applications now use the framework's automatically\nenforced schema contracts instead of constructing and validating a second\nschema object inside each controller action.\n\n## Generate a complete web application\n\n```bash\namber new pet_tracker --type web\ncd pet_tracker\nshards install\namber assets check\namber generate scaffold Pet name:string:required species:string:required adopted:bool\namber database migrate\ncrystal spec\namber watch\n```\n\nThe generated project pins canonical Amber `2.0.0-beta.5`, uses ECR, Grant,\nSQLite, Micrate, local front-end assets, and a manifest-backed asset pipeline.\n\n## What changed\n\n- Resource scaffolds bind `PetSchema` automatically to `create` and `update`\n  and read typed request-local values with `validated_as(PetSchema)`.\n- HTML form schemas declare URL-encoded input and return the generated ECR form\n  with visible field errors and HTTP 422 when a well-formed request is invalid.\n- Malformed or unsupported form bodies preserve the framework's explicit 400\n  or 415 status instead of being flattened into a generic validation error.\n- Preview API generators bind the same executable schema contract for JSON\n  writes while retaining structured JSON failures.\n- `amber generate schema` teaches the executable controller declaration as the\n  primary application path; direct construction remains available for isolated\n  schema unit tests.\n- The Unix and Windows generated-app smoke harnesses can test an exact framework\n  repository and commit during coordinated development, while normal and\n  release CI now exercise the published beta emitted by the template.\n\n## Upgrade compatibility\n\nAmber's deprecated `params.validation` API remains functional. Existing Amber\napplications can update the framework first, verify their current behavior,\nand migrate validation one controller action at a time. CLI 2.0.6 changes new\ngenerators; it does not force an existing application to regenerate its\ncontrollers.\n\n## Release proof\n\n- 412 Amber CLI examples pass.\n- Apple Silicon macOS and x86_64 Linux release-style binaries generate, build,\n  migrate, run, and exercise the complete web application.\n- Linux ARM64 and Windows x86_64 compile and run the generated web application\n  in GitHub Actions.\n- The Pet Tracker smoke proves invalid HTML form input returns one HTML\n  document with status 422 and a visible field error before proving persisted\n  create and PATCH update behavior.\n- Fingerprinted CSS, JavaScript, SVG, and favicon responses retain integrity,\n  MIME, immutable caching, URL rewriting, and gzip checks.\n\nWindows remains a source-build compatibility path; this release publishes CLI\narchives for Apple Silicon macOS, x86_64 Linux, and ARM64 Linux.\n","release_id":370087579,"release_title":"Amber CLI 2.0.6","release_url":"https://github.com/amberframework/amber_cli/releases/tag/v2.0.6","source_commit":"1cba58bdfad27ce1731e73a55002460594958571","tag_name":"v2.0.6"},{"is_prerelease":false,"list_of_assets":[{"asset_title":"amber_cli-darwin-arm64.tar.gz","download_url":"https://github.com/amberframework/amber_cli/releases/download/v2.0.5/amber_cli-darwin-arm64.tar.gz","github_reported_digest":"sha256:ccd29c59b4dc8666084376a4529ec67a1d7d7d48aa4736b09f8697da4d2b99d3","size_bytes":1469169},{"asset_title":"amber_cli-darwin-arm64.tar.gz.sha256","download_url":"https://github.com/amberframework/amber_cli/releases/download/v2.0.5/amber_cli-darwin-arm64.tar.gz.sha256","github_reported_digest":"sha256:51a72f2a63a1cf042eca3d019ca5a2a425334e1a4393a9cea4cf7a8d09f7b5fd","size_bytes":96},{"asset_title":"amber_cli-linux-arm64.tar.gz","download_url":"https://github.com/amberframework/amber_cli/releases/download/v2.0.5/amber_cli-linux-arm64.tar.gz","github_reported_digest":"sha256:a28388a750440865589b852024ace203e9b976c48b0231f17b183f1982615a10","size_bytes":6948662},{"asset_title":"amber_cli-linux-arm64.tar.gz.sha256","download_url":"https://github.com/amberframework/amber_cli/releases/download/v2.0.5/amber_cli-linux-arm64.tar.gz.sha256","github_reported_digest":"sha256:e3ca9a32baa865f8488a7753ea384ac5b6c4c03e43a41f9fb22beb44f3ec9ee9","size_bytes":95},{"asset_title":"amber_cli-linux-x86_64.tar.gz","download_url":"https://github.com/amberframework/amber_cli/releases/download/v2.0.5/amber_cli-linux-x86_64.tar.gz","github_reported_digest":"sha256:957ece546986145a9f9b8d08054e7ae1134eaeaecf7badd5ffc8f2e54debbff9","size_bytes":7517715},{"asset_title":"amber_cli-linux-x86_64.tar.gz.sha256","download_url":"https://github.com/amberframework/amber_cli/releases/download/v2.0.5/amber_cli-linux-x86_64.tar.gz.sha256","github_reported_digest":"sha256:31832825252d1460f1c090f2990ec45074451fa1f7a6b2eed7713edf43ac57d9","size_bytes":96}],"published_at":"2026-08-12T04:36:05Z","release_body":"# Amber CLI 2.0.5\n\nAmber CLI 2.0.5 makes production-safe static assets part of the same supported\nAmber V2 web-app path as Grant, Micrate, and SQLite.

Crystal Alpha with Incremental Compilation — 1.21.0 parity\n\nThis release brings the fork to full parity with upstream **Crystal 1.21.0**\n(released 2026-07-16). Everything in current public Crystal is here, plus the\nfork's additions. That parity is part of this project's promise: the fork\ntracks what's publicly available.\n\n**Upstream sync:**\n- Merged `crystal-lang/crystal` tag `1.21.0` (316 commits since the previous base)\n- Adopted the new `CompilerError`-based error reporting in the fork's wasm-opt/wasm-merge integration\n- WASI event loop updated for the 1.21.0 `EventLoop` interface (`pread`, `sendfile`)\n- The fork's `main.cr` shared-library guard now composes with upstream's new `without_main` flag\n\n**Incremental-compilation correctness fix (new in this release):**\n- Fixed a silent stale-binary bug present in v1.20.0-dev-incremental-3: the\n  module→source-file mapping only records files whose defs pass through\n  `codegen_fun`, so changes to top-level code or trivial method bodies inlined\n  at call sites (e.g. `def self.flag; true; end`) invalidated no LLVM module.\n  All objects were \"reused\", linking was skipped, and the rebuilt binary kept\n  the old behavior — then the fingerprint save poisoned the cache so later\n  rebuilds reported \"no changes\". Module skipping is now disabled for any\n  rebuild whose changed files are not fully attributed in the module mapping;\n  object reuse falls back to the content-based bitcode comparison (still fast,\n  provably correct). Also, forked codegen workers now always report object\n  reuse back to the parent — previously only with `--stats` — which the\n  link-skip decision depends on.\n- If you used `--incremental` with the previous release, clear the cache once\n  (`crystal clear_cache`) in case a stale state was recorded.\n\n**Carried forward from v1.20.0-dev-incremental-3:**\n- Incremental compilation (M1–M8): `--incremental` flag, parse cache, signature\n  tracking, no-change fast path (semantic + codegen skipped entirely), `--no-cache`\n  / `CRYSTAL_NO_CACHE` escape hatches, zero overhead when not enabled\n- First-class iOS and Android linker integration and `--shared` output mode\n- watchOS target support (`aarch64-watchos`, `aarch64-watchos-simulator`)\n- WASI/wasm32 frontend improvements and CI\n\n**Verified on this release (Apple Silicon, macOS 26, release-built compiler):**\n- Bootstraps with brew Crystal 1.20.3 + LLVM 22.1.8\n- 9-check incremental regression matrix passes (body-only, top-level,\n  structural, poisoning-recovery, sequential codegen, fast-path, flag guards)\n- Kemal app, full O0 build: stock rebuild ~2.2s; `--incremental` no-change\n  rebuild **0.26s** (semantic + codegen + link all skipped); cold-build\n  overhead ~6%; rebuild after editing an unmapped (top-level) file ~2.4s —\n  the new correctness fallback, on par with stock rather than faster,\n  by design\n\n**Build it:**\n```bash\ngit clone --branch v1.21.0-incremental-1 https://github.com/crimson-knight/crystal\ncd crystal\nLLVM_CONFIG=$(brew --prefix llvm)/bin/llvm-config make crystal release=1\n./bin/crystal --version   # Crystal 1.21.0 [...]\n```\n","release_id":356854493,"release_title":"Crystal Alpha 1.21.0 — upstream parity + incremental correctness fix","release_url":"https://github.com/crimson-knight/crystal/releases/tag/v1.21.0-incremental-1","source_commit":"9c1e8ec64f6be6343e90d3979bc9536c4b050292","tag_name":"v1.21.0-incremental-1"},{"is_prerelease":false,"list_of_assets":[{"asset_title":"crystal-alpha-1.20.0-dev-incremental.tar.gz","download_url":"https://github.com/crimson-knight/crystal/releases/download/v1.20.0-dev-incremental-3/crystal-alpha-1.20.0-dev-incremental.tar.gz","github_reported_digest":"sha256:67170994411824b81330a2603896c731db204f4ad286286c960a41aca29543c1","size_bytes":7263433}],"published_at":"2026-02-18T18:44:06Z","release_body":"## Crystal Alpha with Incremental Compilation\n\n**Optimized incremental compilation infrastructure (M1-M8):**\n- Gate overhead behind `@incremental` flag (zero cost in normal mode)\n- Add `--no-cache` flag + `CRYSTAL_NO_CACHE` env var\n- Deduplicate cache loads, skip MD5 on cold builds\n- Reuse ParseCache ASTs, eliminate double file reads\n- Fix GC crash in parallel semantic checkers\n- Progress tracker stages for Signatures + Cache save\n\n**Benchmark Results (release build, semantic-only):**\n| Framework | Files | Stock | Warm | Speedup |\n|-----------|-------|-------|------|---------|\n| Kemal | 101 | 5.5s | 1.4s | 3.9x |\n| Lucky | 363 | 5.5s | 1.6s | 3.5x |\n| Athena | 888 | 5.7s | 1.8s | 3.2x |\n| Amber | 2,446 | 11.5s | 2.2s | 5.2x |\n\nInstall: `brew install crimsonknight/crystal-alpha`","release_id":287821876,"release_title":"Crystal Alpha 1.20.0-dev-incremental-3","release_url":"https://github.com/crimson-knight/crystal/releases/tag/v1.20.0-dev-incremental-3","source_commit":"d597126ac02da4ebdb9d0421b25a865dcb7af1ea","tag_name":"v1.20.0-dev-incremental-3"},{"is_prerelease":false,"list_of_assets":[{"asset_title":"crystal-alpha-1.20.0-dev-incremental.tar.gz","download_url":"https://github.com/crimson-knight/crystal/releases/download/v1.20.0-dev-incremental-2/crystal-alpha-1.20.0-dev-incremental.tar.gz","github_reported_digest":"sha256:39455284c519a08a384f2c5236d690f0b95994f1f3b43fa16a1282fe23d9b6c8","size_bytes":21670989}],"published_at":"2026-02-17T15:55:35Z","release_body":"## Crystal Alpha -
