📝 WalkthroughWalkthroughThe PR adds public ChangesNamespace operations
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds process, permission, and symlink operations, but its new tests still use an assertion pattern that may fail independently of the operation being tested, which can obscure regressions; merge is reasonable with owner awareness and follow-up to make those tests reliable.

- Around line 720-728: Update the filesystem tests so each catch expression
returns its Boolean result directly from a helper function instead of binding it
to a local such as threw; keep path cleanup in the caller after invoking the
helper, including the corresponding cases around the other affected test ranges.

## Summary - add comprehensive release notes for the independent `baml_language` 0.17.0 release line - separate user-facing features, breaking and compatibility changes, fixes, performance work, and internal changes - synchronize the canary version, SDK packages, bridge runtime identities, generated Node loader guards, and VS Code extension to `0.17.0` ## Verified comparison range - previous release: `baml-language-0.16.0` at `2e021b3429db8769656e9b8646657c1863789169` - reviewed product target: `baml-language-source-c0153b20108bc428b77a53128b9a59ddeb4e2b42` at `c0153b20108bc428b77a53128b9a59ddeb4e2b42` - the reviewed product target was also `origin/canary` when the updated notes were prepared - full product comparison: BoundaryML/baml@baml-language-0.16.0...baml-language-source-c0153b20108bc428b77a53128b9a59ddeb4e2b42 The product range contains 43 monorepo commits. The notes cover every merged PR in the range that touched `baml_language/`, plus the baml_language-specific macOS test suppression and binary-size baseline workflow update. The post-BoundaryML#4424 review added BoundaryML#4427, BoundaryML#4431, BoundaryML#4432, BoundaryML#4433, BoundaryML#4434, BoundaryML#4103, and BoundaryML#4435. BoundaryML#3975 and BoundaryML#3510 are in the monorepo comparison but are excluded because they change only the main engine/docs release line. Other unrelated documentation, website, JetBrains, on-call, and general monorepo changes are also excluded. The five commits in this PR add and refine the changelog and mechanically prepare release metadata; they do not add product behavior beyond the reviewed target. ## Release safety This PR remains draft. Its `baml_language/release.toml` change is the documented canary release request: merging it to `canary` after green CI would dispatch the production 0.17.0 release workflow. Do not merge or mark ready until Sam explicitly approves the release. No package was published, no release tag was created or pushed, no artifact was uploaded, and no production release workflow was triggered during preparation. ## Validation - `scripts/baml-language-version sync` - `scripts/baml-language-version check` - `scripts/baml-language-version show` → `0.17.0` - `scripts/baml-language-version compute --channel canary` → `0.17.0` - `python3 -m unittest scripts.tests.test_baml_language_version scripts.tests.test_release_pipeline_contract` — 39 passed - `cargo test --manifest-path baml_language/Cargo.toml -p baml_version` - `mise run validate-markdown` from `baml_language/` - changed-file `prek` hooks, including Cargo formatting, Clippy, C++ formatting, TOML checks, and Markdown validation - `git diff --check` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Added system and filesystem capabilities, cryptography utilities, time arithmetic, assertions, bitwise operations, improved indexing, toolchain pinning, and LSP code actions. - Added stable merge sorting for array helpers. - **Bug Fixes** - Improved language behavior, diagnostics, CLI evaluation, playground workflows, and language-server synchronization. - **Breaking Changes** - Updated string APIs, function field requirements, prompt syntax, and type-checking behavior. - **Documentation** - Added release notes for version 0.17.0. - **Release** - Published version 0.17.0 across supported SDKs and tooling. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
