v1.7.0

Repository tooling and formatting. Specification version unchanged: 1.0.0. No specified behavior, test, or fixture changes; every tool's help text is unchanged.

• Pre-commit hooks (.pre-commit-config.yaml): formatting and linting (ruff, ruff-format, Prettier, doctoc, markdownlint-cli2, proselint, codespell), type checking (ty), secret and credential scanning (gitleaks, detect-aws-credentials, detect-private-key), EditorConfig enforcement, and file-integrity checks. New configuration files: .markdownlint-cli2.yaml and .proselintrc.json.
• Formatting: specifications, user manuals, project READMEs, and shared/CLI-CONVENTIONS.md are reformatted (generated tables of contents, aligned tables) with no change in wording; normative help text is preserved verbatim. The reference models and tooling are formatted with ruff.
• Repository hygiene: an extended .gitignore, EditorConfig and linter settings that keep raw test fixtures untouched, and aligned conditional assignments in the Makefile.

Language repositories should pin their sdlc-curriculum submodule to this tag. Repositories upgrading from v1.5.0 or earlier also need a workspace for each of Projects 11–52 (added in v1.6.0).

v1.6.0

Adds the applications-programming track: Projects 11–52, adapted from R. Johnsonbaugh and M. Kalin, Applications Programming in ANSI C (3rd ed., 1996). Specification version unchanged: 1.0.0. Nothing changes for Projects 00–10, so existing implementations need no changes.

• 42 new projects (11-kinder … 52-spacecraft), siblings of Projects 00–10. Each has a URD, SRS, user manual, 10 public and 10 hidden black-box tests, a reference model per tool, and an assignment/ workspace. They add 53 dp- tools (65 in total), and the suites grow to 1060 tests.
• CLI-CONVENTIONS §10 (CONV-32 … CONV-38), for Projects 11–52: tokens and line numbers, integer/real grammars, located data diagnostics, FIX/GEN number formatting, optional prompts on stderr (--prompt), the Ctrl-Z end-of-file marker, and the ANSI C rand() generator with --seed. Also: CONV-25 names the write error diagnostic, CONV-34 allows continuing diagnostics, and CONV-18 lists dp-chk-sort.
• Textbook data files (bargraph.in, students.dat, sched.in, films.dat, sales.rpt, names.dat, distance.dat) are included byte-for-byte as fixtures.

Language repositories should pin their sdlc-curriculum submodule to this tag and add a workspace for each new project (their check-repository target requires one for every project in curriculum.toml).

v1.5.0

Tooling and CI hardening found during the Project 00 implementations. Specification version unchanged: 1.0.0. No specification, test, or fixture changes.

• CI template (shared/ci/cross-platform-ci.yml): CI result now checks every job of its run attempt through the Actions API (a matrix job's combined result can hide a cancelled leg), and CI runs weekly to catch toolchain drift. Language repositories should apply the same ci-result job and schedule trigger.
• Language skeleton Makefile: the TEMPLATE: marker check searches only git-tracked files, so dependency folders inside a project are never searched.

Language repositories should pin their sdlc-curriculum submodule to this tag.

v1.4.0

Clarifications from the first round of implementations. Specification version unchanged: 1.0.0.

• CONV-12 (scan order): only option syntax errors compete with --help/--version during the scan; operand and option-value errors are detected after it. Project 00 FR-07/FR-09 updated, and hidden test 10 gains a step (dp-hello extra --help prints the help). Implementations that reported the operand must be updated.
• CONV-31 (resource limits): NFR memory limits apply to native builds; managed and interpreted runtimes are measured above their runtime baseline.

Language repositories should pin their sdlc-curriculum submodule to this tag.

v1.3.0

Script launchers on every OS. Specification version unchanged: 1.0.0.

• The black-box runner runs #! script tools on Windows by starting their interpreter directly (resolved on PATH), never through cmd.exe. Interpreted-language implementations can ship a #! launcher instead of an .exe.
• New self-test (make launchers, part of make check) verifies this on Linux, macOS, and Windows.
• BASE-MAKEFILE: BIN_DIR may contain #! scripts; new LIBDIR ($(PREFIX)/lib/dialectic-playground) for script payloads.

Language repositories should pin their sdlc-curriculum submodule to this tag.

v1.2.1

Tooling fixes. Specification version unchanged: 1.0.0.

• Native macOS CI (curriculum and the language CI template) installs current GNU Make; macOS ships 3.81, below BASE-MAKEFILE's 3.82 minimum.
• The language skeleton's toolchain example no longer uses tee /dev/stderr (unsupported by some Windows toolchains).

Language repositories should pin their sdlc-curriculum submodule to this tag.

v1.2.0

Language repository skeleton. Specification version unchanged: 1.0.0. No implementation changes are required.

• shared/templates/language/: the standard root Makefile for language repositories. make check covers the repository, the toolchain versions, and every project listed in IMPLEMENTED; it also provides roundtrip.
• shared/ci/cross-platform-ci.yml: make-driven CI (container make check; native make check roundtrip on Linux, macOS, and Windows) that needs no edits as projects are implemented.

Language repositories should pin their sdlc-curriculum submodule to this tag.

v1.1.0

Container-first tooling. Specification version unchanged: 1.0.0. No implementation changes are required.

• BASE-MAKEFILE is container-first: every goal runs in the language repository's toolchain container (Podman, then Docker, then the local system; override with DP_RUNTIME=podman|docker|local). install, uninstall, and help stay on the host.
• New shared tooling: tools/dp-run and tools/container.mk (byte-identical to the canonical copies in dialectic-playground/.github).
• Language CI template: a container job per project plus native jobs on Linux, macOS, and Windows, with a shared-tooling drift check.
• Assignment templates document the Containerfile requirement: the language's official image (pinned by digest) plus make and python3.
• Versioning policy: release tags are now separate from spec_version.

Language repositories should pin their sdlc-curriculum submodule to this tag.

v1.0.0

First release of the specification-driven SDLC curriculum.

• Eleven projects (00-hello-world … 10-sys-monitor): URD, SRS, user manual, and 10 public plus 10 hidden byte-exact black-box tests each.
• Shared CLI conventions (CONV-01 … CONV-30), the language-neutral BASE-MAKEFILE contract, white-box document templates, and the cross-platform CI template for language repositories.
• Spec version 1.0.0 (curriculum.toml), matching every tool's --version output.
