This project uses towncrier and the changes for the upcoming release live in changelog.d/.

0.1.12 - 2026-02-13

Added

  • Added --since/--until time-range filtering to devqubit list, devqubit doctor command for stale run recovery, and full RegistryProtocol alignment for remote, S3, and GCS backends (context managers, connection lifecycle, time-range queries).
  • The runs table now shows a live-ticking Duration column for running experiments. New runs and status changes appear automatically without page refresh. (#47)
  • Added devqubit-cudaq adapter for NVIDIA CUDA-Q. Track sample() and observe() executions with automatic kernel artifact capture (JSON, MLIR, QIR), target snapshots, and UEC-compliant result envelopes. Install with pip install "devqubit[cudaq]". (#54)
  • Added metric time-series tracking with automatic background persistence and live SVG charts on the run detail page. Metrics logged with step are batch-inserted into a dedicated metric_points table every 10 seconds, keeping memory and I/O constant regardless of run length. All storage backends (local, S3, GCS, remote) support the new read/write API. (#60)

Changed

  • Unified pagination response on GET /api/runs (adds total, offset, has_more)
  • ExportRunButton now routes requests through ApiClient instead of raw fetch(); the unused apiBaseUrl prop has been removed. (#48)

Fixed

  • Fixed inconsistent type coercion for the != query operator, ensured SQLite connections are not reused after a failed rollback, respected Config.capture_pip when capturing environment, stabilized ULID generation by pinning a single ULID library, closed registries at the end of a run, added per-process caching for pip freeze, lazily loaded plugins to avoid import-time side effects, and rejected parameter keys containing dots. (#46)
  • Fixed run lifecycle: RUNNING state is now persisted immediately on context entry, SQLite connection leaks in multi-threaded usage are resolved (including a Python 3.12+ WeakSet crash), and all exceptions inherit from DevQubitError. (#47)

0.1.11 - 2026-02-04

Added

  • Added RemoteStore and RemoteRegistry for HTTP-based centralized tracking. (#44)

0.1.10 - 2026-01-30

Changed

  • Migrated web UI from Jinja/HTMX to React + TypeScript for improved maintainability. (#41)

0.1.9 - 2026-01-28

Added

  • Add run deletion from UI via detail page modal or inline table buttons. (#37)

Changed

  • Optimized storage backends for scale (S3/GCS local index, SQLite connection pooling, GC pagination). (#38)

0.1.8 - 2026-01-25

Added

  • Added run_name display throughout the web UI. Runs now show human-readable names in tables, detail views, and comparison dropdowns. The Run class exposes a public run_name property.

0.1.7 - 2026-01-24

Fixed

  • Fix list_runs failing with "no such column: name" when filtering by run name due to missing run_name column in queries.

0.1.6 - 2026-01-22

Added

  • UEC-first architecture with strict adapter contract enforcement:

    • parametric_hash and executed_parametric_hash in ProgramSnapshot for VQE support
    • canonicalize_bitstrings() for consistent bit order normalization to cbit0_right
    • ProgramMatchStatus enum for detailed comparison reporting
    • MissingEnvelopeError when adapter run missing envelope (use strict=False for migration) (#15)

  • Support referencing runs by name via --project flag in CLI and project parameter in API functions (diff, pack_run, verify_baseline). (#34)

Changed

  • UEC ExecutionEnvelope is now the single source of truth for diffs/verification: adapter runs must emit a schema-valid envelope; "non-strict" fallback/synthesis for adapter runs was removed. Manual runs still synthesize a best-effort envelope. Program comparison now distinguishes structural vs parametric hashes and results are canonicalized across bit orders.

  • Redesigned public API surface: added high-level verify_baseline(), new devqubit.runs module for run navigation, devqubit.errors for public exceptions, devqubit.adapters for extension API, moved low-level symbols to appropriate submodules. (#17)

0.1.5 - 2026-01-13

Changed

  • Breaking: Align UEC Envelope 1.0 schemas/models and update all adapters to emit consistent producer/device/program/execution snapshots and unified artifact references. (#14)

Fixed

  • Fix devqubit-ui standalone installation by importing directly from devqubit_engine instead of the devqubit metapackage, and fixed ArtifactRef lazy import path. (#10)

0.1.4 - 2026-01-11

Added

  • devqubit-ui can now be installed and run independently of the full devqubit metapackage.

Fixed

  • Fix top-level imports from devqubit_ui by exposing run_server and create_app. (#9)

0.1.3 - 2026-01-10

Added

  • DEVQUBIT_HOME environment variable is now respected by the UI server for custom workspace locations.

Fixed

  • Workspace context preserved across navigation links when using multi-workspace configuration.

0.1.2 - 2026-01-10

Added

  • Add workspace selector to UI header. When multiple workspaces are configured, users can see and switch between them directly from the navigation bar.

0.1.1 - 2026-01-07

Added

  • User menu component in the base UI template with support for current_user context variable.

Fixed

  • Corrected default workspace path resolution on Windows when DEVQUBIT_HOME is not set.

0.1.0 - 2026-01-07

Added

  • Initial public release of devqubit (core + engine + adapters + optional local UI).
