Two language-surface changes lead: sum-type eliminators unify on+`match` (scrutinee-first), and the primitive set is tentatively finalized — `strings.lines`/`unlines`+are removed in favour of `hydra.formatting` term helpers. A symlink-aware filesystem family lands+across all ten hosts, and Hydra's own build system continues its migration into Hydra.++**Backward-incompatible.** The `cases` -> `match` rename and the `strings.lines`/`unlines` removal+both change the published kernel surface. Code written against 0.17.4 that uses `Optionals.cases`+or `strings.lines`/`strings.unlines` must be updated.++### Highlights++- **Sum-type eliminators unify on `match`** ([#615](https://github.com/CategoricalData/hydra/issues/615)):+ the `cases`/`match` helper pair is flipped to a single scrutinee-first `match` convention across the+ Haskell, Java, Python, and Scala DSLs, the `optionals.cases` -> `optionals.match` kernel primitive,+ and the corresponding implementations in TypeScript and all four Lisp dialects.+- **Primitive set tentatively finalized** ([#417](https://github.com/CategoricalData/hydra/issues/417)):+ `strings.lines` and `strings.unlines` are removed as primitives; their semantics are preserved as+ `hydra.formatting.lines`/`unlines` term helpers, with overlay implementations dropped across all ten+ hosts and callers repointed.+- **Symlink-aware filesystem primitives** ([#666](https://github.com/CategoricalData/hydra/issues/666)):+ `status(followLinks)`, `createSymlink`, and `readSymlink` land with native implementations for every+ host — Haskell, Java, Python, Scala, TypeScript, Clojure, Common Lisp, Scheme, and Emacs Lisp.+- **Build system promotion continues** ([#416](https://github.com/CategoricalData/hydra/issues/416)):+ adds `hydra.build.walk` extension-glob helpers (`extensionOf`/`filterByExtension`/`matchesExtension`)+ and `hydra.build.comparereportlogic`, a set of pure snapshot-compare decision helpers.++### Bug fixes++- **`math.range` was inclusive of both bounds** ([#647](https://github.com/CategoricalData/hydra/issues/647)),+ silently fabricating an extra element in index arithmetic.+- **Java coder TCO-`cases` codegen** dropped enclosing-method type parameters from union-variant casts+ (found via [#666](https://github.com/CategoricalData/hydra/issues/666)).+- **`ShaclRdf` promoted to a DSL module** ([#652](https://github.com/CategoricalData/hydra/issues/652))+ so the SHACL pipeline works outside Haskell.+- **Cold-seed shim portability**: the R22 bootstrap shim used GNU-only `\+` and `\b`, which fail under+ BSD `sed` on macOS ([#417](https://github.com/CategoricalData/hydra/issues/417)).+- **Bootstrap Haskell target missing `unix`**: the demo's static `package.yaml` was not updated when+ `System.Posix.Files` entered the kernel overlay, breaking every `*-to-haskell` bootstrap cell+ ([#670](https://github.com/CategoricalData/hydra/issues/670)).+- **Bootstrap comparison scored Scala and TypeScript cells as passing without comparing anything**:+ `compare_output`'s target switch was missing both languages, so the baseline path was malformed,+ every file counted as "no baseline found", and a zero-file comparison reported `pass`. A Scala or+ TypeScript *target* cell could never fail ([#671](https://github.com/CategoricalData/hydra/issues/671)).++### Known issues++- A pre-#630 post-generation text pass rewrites `hydra.lib.<sub>` -> `hydra.overlay.<lang>.lib.<sub>`+ in generated **doc comments** as well as code, because its quote-prefix guard does not recognize+ mid-sentence prose references. Affects two kernel doc strings in `src/main`+ (`hydra.error.system`, `hydra.error.packaging`) plus ~20 generated docstrings in the test tree;+ cosmetic only, no behavioral impact. Tracked as part of+ [#633](https://github.com/CategoricalData/hydra/issues/633).+- Bootstrap comparison diff detail is not persisted to the run directory+ ([#671](https://github.com/CategoricalData/hydra/issues/671)).++---++## [0.17.4] - 2026-08-09++Point release on the 0.17.x line. Fixes an inference bug that mis-typed generated Java and Python for+`readFile`, adds the `divide` primitive, and restores `hydra-ext` to the published package set. Release+validation also surfaced a family of pre-existing cross-host code-generation defects — none of which the+per-host CI jobs can catch, because only the bootstrap exercises one host generating *another*.++### Highlights++- **Output-only nominal generalization fixed** ([#637](https://github.com/CategoricalData/hydra/issues/637),+ with [#638](https://github.com/CategoricalData/hydra/issues/638) /+ [#639](https://github.com/CategoricalData/hydra/issues/639) /+ [#640](https://github.com/CategoricalData/hydra/issues/640)): a nominal type appearing only in the+ *output* position of a primitive's signature was generalized to a free type variable instead of resolving+ as nominal, mis-typing the generated Java and Python for `readFile`. Also widens universe closure and adds+ a `kernelTypeUniverse` helper, an effect DSL builder, and `effects`/`files`/`text`/`system` lib wrappers.+- **`divide` primitive** ([#317](https://github.com/CategoricalData/hydra/issues/317)): now present in the+ published kernel. This also clears the cold-clone dangle, since a cold seed against published 0.17.4+ resolves `DefMath.divide`.+- **`hydra-ext` republished** ([#636](https://github.com/CategoricalData/hydra/issues/636)): back in the+ published set after its absence from 0.17.1–0.17.3, shipping to Hackage and PyPI.++### Bug fixes++- **Overlay-lib redirection skipped for the Haskell target**+ ([#630](https://github.com/CategoricalData/hydra/issues/630)):+ the Java, Python, Scheme, Clojure and Common Lisp heads resolved the overlay lib directory using an+ all-lowercase path and did not lower-case the names they scanned. Haskell's overlay tree is capitalized+ (`Hydra/Overlay/Haskell/Lib/`), so every `hydra.lib.*` redirect silently failed and the generated Haskell+ imported `Hydra.Lib.*` instead of `Hydra.Overlay.Haskell.Lib.*`, producing hundreds of type errors. The+ defect was invisible on case-sensitive filesystems, where the failed directory check falls back to a+ hard-coded list that happens to be correct. The Python head carried *two* independent copies of this scan;+ only the one in `generation.py` feeds the Haskell coder.+- **Lisp-as-host bootstrap** ([#520](https://github.com/CategoricalData/hydra/issues/520),+ [#630](https://github.com/CategoricalData/hydra/issues/630)): the four Lisp head decode drivers called+ `from_json` with a stale 4-argument signature, and the Lisp bootstrap-driver coders were not pre-bound with+ `overlaySubs`.+- **Python-as-host dropped the `Graph` argument** ([#630](https://github.com/CategoricalData/hydra/issues/630)):+ `overlaySubs` was not threaded into the Python head's `write_*` wrappers.+- **Clojure `resolve-coder` and `decimal-to-float32`**+ ([#630](https://github.com/CategoricalData/hydra/issues/630)): a stray parenthesis closed a `case` early,+ making an unsupported-default block run unconditionally; and `(float (.doubleValue ...))` threw on+ `Float.MAX_VALUE`, now saturating via `(.floatValue (bigdec x))`.+- **Cold-seeder failed on macOS** ([#630](https://github.com/CategoricalData/hydra/issues/630)): the #376+ cold seeder used a bare `sed -i -e`, which is GNU-only and aborts immediately under BSD `sed`.++### Release engineering++- **Review checkpoint before Maven Central publishes**+ ([#591](https://github.com/CategoricalData/hydra/issues/591)): `HYDRA_JAVA_PUBLISH_HOLD=1` uploads the+ aggregated Java deployment as `USER_MANAGED`, so it validates and then holds for review instead of+ publishing automatically. This mirrors `HYDRA_SCALA_PUBLISH_HOLD` and makes an upload reversible — a held+ deployment can be dropped, whereas an automatic one cannot be undone.++### Known issues++- **`hydra-ext` is not published to Maven Central**+ ([#643](https://github.com/CategoricalData/hydra/issues/643)): it does not compile for the Java target,+ because the visitor-pattern inner interface the Java coder emits collides with the enclosing `Visitor`+ type in `hydra.cpp.syntax`. Only Java is affected; the Python coder emits sibling classes rather than+ nested ones. ext ships to Hackage and PyPI at 0.17.4 and is expected to rejoin the Java set once fixed.+- **TypeScript no longer self-hosts**+ ([#642](https://github.com/CategoricalData/hydra/issues/642)): the TypeScript host's JSON decoder fails to+ decode most of the kernel, so `typescript-as-host` code generation is broken. No published artifact is+ affected — `dist/typescript` is generated by the Haskell host and passes its test suite.+ ## [0.17.3] - 2026-08-01 Point release on the 0.17.x line, focused on **release-artifact integrity**. The 0.17.2 release shipped
