Shasta Software - Release Notes - V. 2.5.9

This article summarizes the software revisions, feature enhancements, and corrections implemented between versions v2.5.5 and v2.5.9 of the Shasta software platform. Version v2.5.9 is the latest validated build for production and field use.

 

Software Release Notes

Validated Build: v2.5.9
Release Date: October 2025

Revision History

Version 2.5.5

  • Corrected button order in the Sequence Editor — the Import and Export buttons had been reversed in a prior update.

  • Added a new configuration option to enable pre-priming all tips prior to each dispense pass (applicable to Standard and Meta protocols only).

  • Updated Run Synthesis to automatically prime all tips ready for dispense before the start of each dispense-pass series (Standard and Meta protocols only).

Version 2.5.6

  • Modified Run Synthesis pressure monitoring behavior:

    • When pressure goes out of range, the system now logs the event silently instead of displaying an interrupting dialog.

    • The synthesis automatically continues once pressure returns to the acceptable range.

    • Other pausable conditions (e.g., Lid Open, Leak Detected) will still trigger user dialogs requiring acknowledgment before resuming.

Version 2.5.7

  • Updated Backup/Restore functionality to no longer remember the previous archive path or filename.

  • Added a new configuration option to restrict plate movement unless chamber pressure is within acceptable limits.

  • Enhanced the Manual Control, Priming, and Calibrate Position screens to:

    • Display current lid switch and chamber pressure status.

    • Only allow plate motion when both lid closed and pressure OK conditions are met, based on configuration settings.

  • Updated Dispense Calibration to move the plate only when lid and pressure conditions are verified as good.

Version 2.5.8

  • Added advanced Run Synthesis controls, allowing users to:

    • Start synthesis from a specific base.

    • Pause before a specified base.

    • Pause automatically after a defined number of hours or minutes.

Version 2.5.9 — Validated Build

  • Modified Run Synthesis to disable Pause Before Base X and Pause After X Hours/Minutes features when running MAP protocols.

Status:
✅ Validated build for production and field use (v2.5.9)

Summary of Key Improvements

  • Enhanced pressure and motion safety interlocks for improved operator protection.

  • Added flexible synthesis controls (start/pause/resume logic).

  • Improved UI consistency across Manual Control, Priming, and Calibration screens.

  • Reduced potential for synthesis interruptions due to transient pressure fluctuations.

  • Improved pre-dispense priming reliability for Standard and Meta protocols.
