Feb 1, 2026February 2026 monthly summary for Opentrons development efforts focused on security-enhanced, scalable authentication flows and infrastructure reliability. Delivered a foundational OAuth 2 authentication ecosystem in auth-server, with token and introspection endpoints, and migrated authorization scopes to a shared server-utils module to align cross-service permissions. Deprecated legacy auth endpoints and updated documentation to reflect the new authentication flow, enabling safer, more maintainable integration across apps and robot-server. Implemented CI/build/test infrastructure enhancements to improve reliability, including fixes to Makefile quoting for correct systemd and version file handling, and targeted test configuration improvements.

Jan 1, 2026January 2026 performance for Opentrons/opentrons focused on delivering core Protocol Designer enhancements, stabilizing concurrency in Thermocycler execution, expanding automation UX, and advancing maintainability. Key work includes enabling default, non-blocking concurrent Thermocycler actions with nested timelines, migrating legacy files to the new non-blocking regime, and implementing safety checks in protocol execution. The team added dynamic transformation support for turning profile steps into non-profile steps (and back) with corresponding state-management updates to handles related steps (e.g., pauses). User experience improvements include automatic "wait for temperature" modals for Temperature Module and Heater-Shaker steps, with a perma-dismiss option and tutorial integration. Code quality and infra improvements were a major focus, covering granular lodash imports, lint rules, docs/build fixes, test alignment, and Python tooling and packaging hygiene. Foundational infrastructure work was also advanced, including an auth-server skeleton and test stabilization efforts to improve reliability and developer velocity.

Dec 1, 2025December 2025 monthly summary — Opentrons/opentrons Overview: In December 2025, we delivered substantial advances in Thermocycler automation, improved labware rendering accuracy, and stabilized documentation and UI, translating to faster, more reliable experiments and a smoother developer experience. Key features delivered: - Thermocycler Workflow Enhancements and Concurrency: automated wait steps, extended profile support, concurrent execution, and protocol export with a concurrency flag; UI and state-management refactors to support these capabilities. - Labware Rendering and Alignment Improvements: centered labware over slots and alignment consistency across UI components; migrated components to positionMode='passThrough' for visual accuracy. - Labware Corner Offset Bug Fix: introduced corrected labware versions to prevent underground placement; updated default loading to include v2 by default. Major bugs fixed: - Fix Thermocycler steps getting laid out horizontally; improved compatibility with concurrent modules. - Documentation/API Docs Fixes: resolved API docs loading issue and removed misleading scroll workaround for modals. - Minor UI alignment bug: align number to top of step button for better readability. Overall impact and accomplishments: - Business value: reduced protocol development and run times via Thermocycler concurrency; improved throughput and reliability of automated protocols. - Technical impact: stronger data fidelity and UI stability; safer labware placement with corrected corner offsets; easier onboarding through stable docs and cleaner UI. Technologies/skills demonstrated: - Protocol-designer vs step-generation integration for concurrency (EXEC-2009), runExtendedProfile, and protocol export changes. - UI refactors for labware and module rendering; migration to positionMode='passThrough' and deduplication of module state types. - Robust fixes to API docs and micro-UI improvements.

Nov 1, 2025Month: 2025-11 | Repo: Opentrons/opentrons. Delivered Protocol Designer enhancements and targeted code-quality work that drive reliability and business value for complex automation workflows. Key outcomes include robust handling of concurrent Thermocycler profiles within Protocol Designer (duplication, deletion, grouping), reliable lastSelected state, and corrected user-visible step indexing in the timeline, plus improved multi-select behavior across nested profiles. These changes reduce user errors and setup time for complex runs, enabling faster protocol authoring and more dependable executions. Additional work focused on TypeScript safety and test tooling, resulting in safer refactors and a more maintainable codebase. Technologies demonstrated include advanced TypeScript usage, Redux/selector reliability improvements, Vitest/testing tooling, and Vite/config fixes (tslib) to improve local development. Commits also reflect closes on internal tickets (e.g., EXEC-2025, EXEC-2060, EXEC-2024).

Mar 1, 2025In March 2025, Opentrons delivered reliability and capability improvements around labware offsets, labware data modeling, and system stability. Key work included multi-filtered labwareOffsets with default storage/retrieval across robot-server and API client, a shift to real-time offset change notifications, and data-model/schema upgrades that enable advanced labware features while preserving compatibility with schema 2. These changes were complemented by targeted bug fixes (geometry synchronization, cornerOffset handling) and sustained maintenance and tests that improved code quality, test coverage, and migration robustness. The combined outcomes reduce risk, accelerate calibration workflows, and strengthen the platform for future feature work across the API, robot-server, and client layers.
