Projects now open on a proper **home page**: an assistant prompt front and centre, a **Running now** panel showing pipelines still in flight, a **Pick up where you left off** row of your most recently touched studies, pipelines, measurements and conversations, and browse tiles with counts for each area of the project. Ask a question from the home page and it opens a fresh Agent conversation with your question already sent. ## Describe a test in plain English The Lab test scheduler can now **author a protocol from a description**. Type something like "1C/1C cycling for 100 cycles between 4.2 V and 2.5 V with 10-minute rests" and you get back a validated protocol, ready to request. If the description leaves out something that would change what physically runs on the channel, you're asked about it rather than having a value guessed; common conventions (25 °C ambient, CC-CV taper, rest lengths) are assumed and reported back to you. If one of your saved protocols already does the job, it's offered instead of a new one. Anything the generator returns is a protocol the platform accepts — it's validated before you ever see it. ## Test requests get their own page, and export to your cycler Planned tests now open on a **detail page** instead of jumping straight into the edit form, with the request, its scheduling, and its actions laid out separately — so an unscheduled request reads as "not booked yet" rather than a half-empty form. From that page you can **export the request's protocol in a cycler's native format** — Maccor, Arbin, Neware, BioLogic (BT-Lab) or Novonix — preview it, and download it, with no need to re-author the test in vendor software. Exports that need more than one file arrive as a single zip. ## Charge-transfer kinetics in the ECM The Equivalent Circuit Model gained an optional **Butler-Volmer charge-transfer element**. Enabling it adds a symmetric charge-transfer overpotential driven by a new **Exchange current \[A]** parameter, which captures rate-dependent losses that a linear series resistance cannot — nearly linear at low current, logarithmic at high current. It's off by default, so existing models and simulations are completely unchanged, and the new **Charge-transfer overpotential \[V]** output is available when it's on. **Improvements** * ECM simulation results now show a real **voltage components** plot — open-circuit voltage, the series-resistance drop, and one band per RC pair, stacked down to the terminal voltage. * Measurement views gained a **Filter by Steps or Cycles** selector. Measurements with no cycle data — OCV sequences, pulse and DCIR tests, single-pass characterisations — now get the full step filter instead of no filter controls at all, and open on Steps. * **Channel incident history** — taking a channel out of service now records the outage with its cause, category, who reported it and when. A down channel shows a callout with the cause, start time and running duration plus a **Return to service** action, and the channel page lists its past incidents. * Organization admins can manage the **Programs** catalog from a new Programs tab in Organization settings — create, rename and delete the programs used to tag planned tests. * **Protocols are now scoped to a project.** Every project starts with its own editable copy of the standard protocols instead of sharing a read-only library, so edits in one project can't affect another. Existing projects have been seeded with theirs. * Uploading measurement time series now returns immediately and **processes in the background**, with progress and any processing error visible in the measurement list, so large uploads no longer block the request. * Revoking an API key now takes effect **immediately** rather than after a delay. **Fixes** * The Agent widget's **New chat** button now actually starts a blank conversation instead of re-opening the last one. * Reloading the page mid-reply no longer blanks the earlier messages in an Agent conversation — history and the streaming reply are merged rather than one replacing the other. * Failed API-key authentication no longer echoes the submitted key back in the error response; only the key's short prefix is returned. * Sorting or filtering cell specifications by **last-updated** no longer errors — the field is now stored and returned alongside `created_at`. * Transient failures in authentication and membership lookups now report a retryable error with a real cause instead of an opaque failure. * Program names consisting only of whitespace are now rejected, and program-related text meets WCAG contrast requirements. **Improvements** * Pipeline elements now return **typed result objects** — parameter-estimation, optimization, posterior, ensemble, regression and validation results each have their own type, reachable from `Pipeline.results`. A new `iwp.analysis` namespace collects post-fit analyses, including `LinearConfidenceInterval` and `SobolSensitivity`. * Interpolant-valued parameters (for example a measured ambient-temperature profile supplied per objective) now serialise from a plain dictionary, not just from a `pybamm.ParameterValues`. Array-valued parameters round-trip correctly instead of being misread as indexed parameters. **Fixes** * Fixed a memory leak where every fit result held a reference to itself, keeping results alive longer than necessary. A parent result whose child happened to hold equal parameter values also no longer silently loses that child when copied. **Improvements** * New clients for **channel incidents** and for the **background measurement upload** flow, so an upload can be started and its processing state polled from the SDK. * Protocol clients are now project-scoped, matching the per-project protocol change above. * **Breaking (direct `ionworkspipeline` users only):** `result.optimizer_result`, `iwp.OptimizerResult` and `iwp.SamplerResult` are removed in favour of the typed result objects above (`OptimizationResult.x` / `.fun` / `.success`, `PosteriorResult`, …), and `RegressionResult.result` is now `.results`. **Improvements** * **Power \[W]** is now computed when a measurement is processed and stored with the time series, rather than derived on every read. It also stays correct when the current sign is auto-corrected during processing. **Improvements** * A protocol can now be **resumed exactly from a captured point** — its position, loop counts, variables, cycle number and full physical state — so a run can be checkpointed and continued with no rest step and no loss of accuracy. * New **protocol authoring warnings** flag common mistakes before you run anything: mistyped or cross-scope jumps, missing subroutines, loop conditions that can never be satisfied, unreachable steps, voltage limits that contradict the step direction, targets outside the safety window, and rests with a current-based end condition. These are advisory — nothing that runs today stops running — and can be made blocking if you'd rather catch them as errors. * Protocols now report their derived **voltage and current limits** — the minimum and maximum voltage and the peak charge and discharge currents implied by the steps, safety limits and drive cycles. **Fixes** * Maccor and Novonix exports now use the **earliest** duration end condition rather than the last, so a step no longer runs for longer than requested. * Fixed a Novonix export writing a structured safety-limit value where a plain number was expected. * Fixed Arbin loop detection and Neware template handling cases where two divergent code paths disagreed. **Improvements** * **Manage equipment** covers recording and reading a channel's incident history. * **Upload data** covers the background upload flow and how to poll a measurement's processing state.
