Version History

Current Baseline

  • current repository baseline: v0.24.13
  • public docs in this tree describe the v0.24.13 workspace version unless a page explicitly marks a feature as experimental, roadmap, or target-specific

What Changed Recently

v0.24.x

  • Runtime release archives include trust-dev as the developer/workbench CLI. trust-dev agent serve now owns the external agent JSON-RPC server and trust-dev commit, trust-dev docs, and trust-dev test own the project commit, ST API documentation, and ST test workflows, while the matching trust-runtime commands remain deprecated forwarding aliases during the product/workbench CLI split.
  • MQTT I/O now has explicit TLS/mTLS configuration: tls = true requires a CA trust file, optional client certificate/key files enable mTLS, mqtts:// and ssl:// broker schemes imply TLS, and remote plaintext MQTT remains gated by allow_insecure_remote = true.
  • Dependency hygiene now has project cargo deny policy, explicit advisory/allowlist metadata, workspace-scoped cargo machete cleanup, a Rust 1.95 MSRV baseline, patched time 0.3.47, ratatui 0.30, tracked Cargo.lock, Rust 1.95 is_multiple_of cleanup for runtime modulo checks, and full-map doctor reporting for the remaining policy-managed transitive advisories.
  • OSCAT OOP reset behavior, converter parity, API naming, dependency alias, and comparison examples were hardened after external review.
  • OSCAT OOP example validation keeps all catalog/layout/pattern checks in the default Rust suite, while the full 98-project runtime CLI execution sweep is an explicit ignored gate for release or targeted OSCAT validation.
  • HIR default-initializer analysis now rejects non-repeat call expressions used as array defaults and validates repeated array defaults against the element type.
  • Parser recovery for malformed aggregate/positional initializers now uses bounded declaration-aware helpers and mutation-checked recovery tests so bad initializers do not consume following declarations.
  • The OSCAT OOP test fixture now covers reset, multi-scan parity, invalid-limit rejection, FIFO ordering, and version lookup through classic OSCAT.
  • OSCAT OOP now includes the v1.0 component surface for additional controllers, filters, generators, memory, logic, measuring, calendar/RTC, selected device-driver, and building-control objects, plus 49 classic/OOP comparison pairs: 27 hand-written process-first industrial pattern scenarios, 20 compact component-composition showcases, and 2 compact pattern showcases covering state machines, alarm handling, historian/logging records, communication boundaries, and named OOP patterns.

v0.23.x

  • PLCopen Motion now has an object-oriented companion package with itfAxis, command objects, Structured Text unit tests, and five runnable OOP motion examples.
  • OSCAT now has an object-oriented Components companion package with Structured Text parity tests, public docs, and 20 classic/components comparison scenarios.
  • The public docs now define the default truST Structured Text naming standard for new APIs, variables, constants, examples, and inherited-symbol exceptions.

v0.22.x

  • One Project, Every Surface and truST Mesh became named public concepts
  • the public docs were collapsed to six user-facing doors: What Is truST?, Install, Program, Run, Hardware, and Reference
  • Migrate now has canonical ecosystem pages under migrate/*
  • Editor AI tools and the Agent API have separate public scope boundaries
  • public docs checks now guard nav coverage, snippet H1 collisions, list spacing, assets, links, and search expectations

v0.21.x and earlier

  • public docs moved to a question-driven site structure under docs/public/
  • agent and harness surfaces became public documented contracts
  • diagnostics gained a dedicated public code reference
  • Browser IDE, HMI, examples, and operate runbooks were aligned into the docs site
