Our development and testing teams have been busy speaking with beta testers, getting feedback, recording bugs, and making great progress on improving your experience with RoastPATH.

This release is largely bug fixes and feature usability improvements. Some of you may recognize a few items from the list below, though most of these issues only affected individuals or small user groups.

Fuel and Drum Note Handling

• Fixed an issue where fuel events could not be marked as complete if the note status was skipped.
• Resolved the issue of fuel and drum notes not being inserted during a manual roast.

Replay and Adjustment Functionality

• Corrected the behavior where a skipped adjustment would still occur 5 seconds after being ghosted.
• Addressed the issue of recording multiple notes in sequence for the same setting adjustment when adjustment only happened once.

Text Note Management

• Solved the problem where text notes from an underlayed profile were saved to a notebook for a new profile, causing potential clutter.
• Implemented an option to ignore decimal values and only record new fan notes when the 1s place value changes.

Manual Machine Configurations

• Enhanced the ability to add new notes of all types during a roast in manual machine configurations.
• Fixed the issue where trying to add a fan note while roasting on a manual machine caused the app to freeze.

Connection and Refresh Button

• Resolved the issue in version 1.7.1412 where hitting the connection refresh button did not appear to reattempt the connection.

User Interface and Display

• Fixed the problem where certain toggles and event markers remained unchecked or checked incorrectly.
• Corrected the display of BT, ET, and IT on the timer, ensuring alignment with checkbox adjustments.

App Errors and Crashes

• Addressed an unexpected error message when trying to delete a roast profile.
• Fixed the issue where inputting letters in batch size caused the app to freeze and crash.
• Resolved a bug that led to the automatic re-marking of a turning point after attempting to undo it.

Profile and Coffee Management

• Corrected the problem where both previously selected profiles and re-roast profiles were underlayed simultaneously.
• Fixed the duplication of the coffees list after editing an existing coffee.
• Ensured that clicking any favorite profiles toggles the Roast Event dropdown as expected.

Roast Review and Replay

• Addressed inconsistencies in Roast Review and Roast Replay settings related to DT (Drum Temperature) line and underlay display settings.
• Fixed the issue where Replay setting Target Fuel or Fan Hz to 0 during a roast.
• Corrected the unexpected behavior related to editing and saving Coffee in the app.

Miscellaneous

• Fixed the prefilling of unspecified coffee instead of the selected coffee.
• Resolved the issue where manually disabling ignition caused both ignition alerts to appear at the same time.
• Fixed the problem where the reference profile's DT line was displayed but the DT setting was off.

We are excited to announce our latest application update, which includes some great new features and improvements to the performance and stability of the app.

Windows users may have already been updated to version 1.7 through the Microsoft Store, Mac users can use a pre-release (still being tested) version located at the downloads page (linked below).

What's new in this release?

Roast Replay: This new feature automates machine adjustments during the roasting process. By selecting a previous roast, the app will automatically adjust fuel, fan, and drum settings for you. Note that this feature is currently in beta and available by invitation only until our case testing is finished. Learn more about machine compatibility in the Help Center article 'Is my roaster Roast Replay ready?'.

Preheat Chart: Digital roasters will now see a preheat chart in the notebook displaying Drum Temperature and the heat cycle count. This enables users to track the latent heat of their machines and dial in their between-batch protocol.

Drum Temp: If your roasting machine supports it, the drum temperature will now be displayed on the chart and timer. Additionally, you can charge off of the drum temperature instead of bean temperature.

Phidgets on Mac: This update expands the support for Phidgets on Mac that we introduced in version 1.6.

Bug Fixes/Performance Enhancements: We've made various improvements to increase the stability and performance of the app.

Expanded Roaster Configurations: All known Phidget equipped and MODBUS RTU enabled roaster models from any manufacturer are being added to RoastPATH’s machine library. Request integration of your machine by emailing support@roastpath.com.

Downloads Page: We have created a downloads page where you can find both the Mac and PC versions of the app. This way, if we publish a new version that doesn't interact with your computer well, you will be able to go here and install the previous version that was working for you last. We recommend uninstalling the app before installing a new version to ensure the best possible experience.

Latest version 1.7.1412 can be found here by clicking the drop down "Show Other Releases"

We're thrilled about the performance and stability of these new versions. As we are nearing the end of our beta, headed towards a public release, keep your eyes on the forums and your inbox for important updates and more news. Thank you for your continued support!

Good thought, would take quite a bit of heat to disrupt that chipset though.

We've made a few further advancements that are currently in testing and should be released in the next version.

We've made significant improvements over the last few months, many of which have corrected errors causing dropped data. The version being internally tested right now further reinforces the communication between computer and roaster. I'll check in with the team tomorrow during our development meeting to find out when that new version will be released.
