## Changes
{% updates format="full" %}
{% update date="2026-04-15" %}
## v2026.02a
**Changed**
* Allow HTTP API connections from any origin via CORS. In practice, this allows all third party connections to BactoBox®.
**Fixed**
* Fix a very rare data corruption bug. We tracked this bug internally as wal-db-corruption.
{% endupdate %}
{% update date="2026-03-09" %}
## v2026.02
**Added**
* 💻⚗️ Add experimental "growth-curve" measurement group. This includes richer growth analytics, CIZE views, and computed HPI metadata in tables and plots.
* 💻 Add more column filters for the measurement and measurement group tables.
* 💻🧰 Add workshop-only "shipping-qc" measurement group.
* Store additional program settings in the PEDB. This makes it easier to troubleshoot when a program misbehaves.
**Changed**
* 💻 Rework the "Support" page entirely. The overall workflow is the same but the implementation behind it is now consistent with the other pages.
**Fixed**
* Fix "Database is locked" when connecting to BactoBox via USB while a program runs. Behind the scenes, the PEDB now uses a WAL.
{% endupdate %}
{% update date="2026-01-14" %}
## v2026.01
**Added**
* 💻 Add automatic clock synchronization when connected to Access.
* 💻 Add "Measurements" page to Access. Allows you to view and annotate measurements.
* 💻 Add "Measurement group" page to Access. Allows you to create measurement groups and add/remove measurements to them. It also features a plots of the growth curve and CFU correlation.
* 💻 Add MSEC buttons to Access (Measure, Stop, Empty, Clean). Allows you to start/stop programs directly through Access.
* 💻 Add progress bar to Access that shows the outline/outcome of the current program (if any).
* 💻🧰⚗️ Add experimental "SBT Lab" page to Access with live stream of the demodulated signal (from the lock-in amplifier).
* 💻 Add "System info" overview to the top right of Access.
* 💻 Add link to help center for error codes that we show in Access' bottom bar.
* Add PEDB file to the DDB. Makes it easier to troubleshoot (especially now that we have data annotations).
**Changed**
* Change "ml" (millilitre) to "mL" throughout.
* 💻 Rename "Measurements" to "Summary" in Access
* 💻 Rename "Summary" to "Download summary" in Access
* 💻 Hide scroll bars when they are unnecessary in Access
**Fixed**
* 📟 Fix dash entering in a pending state when start execution fails
* Fix snapshot creating a corrupted zip file when biome does not respond.
* Fix issue where fields such as "Software version" were missing data (inside the PEDB's outcome column).
* 💻 Fix overflow/wrap in Access for low screen sizes
{% endupdate %}
{% update date="2025-11-17" %}
## v2025.10b
**Changed**
* 📟 Replace "blank diluent" for "Dilution vial" in QC test.
**Fixed**
* Fix "Execution error: \[Errno 111] Connection refused" when the end user presses Measure. This was due to an issue with corrupt/missing starred.json file.
* Always persist changes to .crs.json files and starred.json files when the user presses *Save*. This avoids an issue where the user presses *Save*, flips the rocker switch shortly after, and ends up with a corrupt/missing starred.json file.
{% endupdate %}
{% update date="2025-10-15" %}
## v2025.10
**Added**
* Deep clean program has two options: 15 minutes and 10 hours.
* 📟 Add 2 steps to the QC test guide screen: 'Clean' and 'Measure on blank diluent'
* 📟 Add 'Set target concentration' screen right before entering in the QC test guide screen.
* Add 50XX error codes related to the blank liquid validation.
* Add liquid info to the extended troubleshooting bundle.
**Changed**
* Replace 'See troubleshooting guide' text in error messages to 'Further instructions: help.sbtinstruments.com'.
* 📟 Disable empty program by default. It is only enabled when the 'There is liquid in the system modal' appears.
* 📟 Change confusing text in the 'Ready' home screen. Now it just displays Ready.
* Remove flush program
* Replace the flush modal for the deep clean modal. It is triggered by 1 week since the last deep clean of any length.
* Merge the 40XX errors to the new error system implemented in bebop
* Replace Clean the system/flow system for Clean the setup to keep it consistent with the help center.
* Change rinse duration in deep clean from 20 to 25 seconds and reduce the soak duration from 20 to 15 seconds.
* Change the QC test durability cost to 0. This includes the Measure on blank diluent step.
