# v0.8.0 — in development

Active development on feature/v0.8. Details in the roadmap and the GitHub milestone.

# v0.7.1 — April 2026

Patch release consolidating conformance-suite coverage, SQL safety hardening, and transition-endpoint semantics for the reference runtime. The IR (intermediate representation — the compiled JSON artifact the runtime consumes) schema is unchanged (still 0.7.0) — no fixture recompilation required for runtimes already passing v0.7.0. Full notes on GitHub.

# v0.7.0 — April 2026

"Polish, observability, developer experience."

• Auto-generated REST API at /api/v1/{content} for every content type. Headless services with no user stories are fully supported.
• Agent observability: the AUDIT verb, auto-generated audit-log content per compute, trace recording with per-level redaction.
• Chat presentation component: any content with role and content fields can render as a conversation surface with integrated input and WebSocket live updates.
• SQL injection defense in depth: identifier validation at IR load, quote escaping, centralized storage module, and a structural test that prevents raw SQL outside it.
• Major refactor of app.py, peg_parser.py, lower.py, and channels.py into smaller focused modules.
• IR version advanced from 0.5.0 to 0.7.0. Full notes on GitHub.

# v0.6.0 — April 2026

"Boundaries."

• Boundary isolation enforcement with an implicit application boundary.
• Cross-boundary identity propagation in restrict mode.
• Audit levels (none, actions, debug) declared per compute.
• Dependent field values via When clauses.
• Compute CEL (Common Expression Language — a small expression sublanguage used in Termin for conditions and computed values) context, snapshots, and scheduler.
• Legacy backend removed (~2,100 lines). Code coverage reached 95.2% on new code.
• 690 tests with zero failures, zero skips, zero xfails. Full notes on GitHub.

# v0.5.0 — April 2026

"Channels, AI Agents, and Mark-as."

• Channels primitive for external integrations (webhooks, Slack, HTTP APIs) declared in the DSL and scoped at the boundary.
• AI agent provider built in alongside the CEL provider.
• Mark ... as semantic highlighting for rows matching an expression.
• WebSocket behavioural tests exercising subscribe / live-update / unsubscribe paths against the runtime contract.
• IR version advanced from 0.4.0 to 0.5.0. Full notes on GitHub.

# v0.4.0 — April 2026

"Simplification: Custom Compute Providers removed in favour of Channels."

• Custom compute providers (subprocess JSON-RPC, CCP package system, executable management) removed. They introduced arbitrary-code-execution risk and OS-specific binary distribution for no benefit over the existing Channel primitive.
• Provider model simplified to two built-ins: a CEL provider (pure expression evaluation, default) and an AI-agent provider (LLM reasoning with a runtime-controlled API surface).
• External integrations now use Channels with explicit endpoints rather than pluggable providers.
• Structural security property added: no arbitrary code execution — only the two built-in providers can run inside the runtime process. Full notes on GitHub.
