Version 1.29.0 Release Notes

Bug Fixes:

• In certain situations, it was possible to submit a strategy that had CRSP equalization set to on when it should not have been. That has been corrected.

• Performance Metric "Powell Pool Elevation (April 1 through October 31) is Above 3,570 Feet | Percent of Months" was updated to only include appropriate month range.

Feature Development:

• Updated the informational tool tip on the Combined Storage Lower Basin Delivery Concept definition in Strategy Creation and Modification to include the new option of discount volumes.

Explanatory Content:

• Added Spanish support to warning messages from loading saved sessions.

• Added Spanish support to Discounted Volume tooltip.

Version 1.28.0 Release Notes

Bug fixes:

• Corrected the first year calculations for year over year time series calculations that were impacted by initial condition assumptions. These are robustness and vulnerability measures of 'Mead and Powell Storage January 1 Volume Decline from Previous Year', 'Mead and Powell Storage January 1 Volume Increase From the Previous Year', 'Glen Canyon Dam Outflow Interannual Variability Between Consecutive Paired Years'.

• Adjusted the font size in the colored sortable list in Trace View so that random strategies don't have a horizontal scrolling bar when it's not needed.

Feature Development:

• Added 8 new performance metrics and 4 new robustness and vulnerability measures.

  • The new metrics are:

    • April 1 Powell Pool Elevation Above 3,550 Feet | Percent of Years

    • April 1 Powell Pool Elevation Above 3,560 Feet | Percent of Years

    • October 1 Powell Pool Elevation Above 3,560 Feet | Percent of Years

    • October 1 Powell Pool Elevation Above 3,570 Feet | Percent of Years

    • Mead Pool Elevation is Between 1,000 Feet and 1,135 Feet | Percent of Months

    • Hoover Dam Calendar Year Outflow is Below 5 Million Acre-Feet | Percent of Years

    • Powell Pool Elevation (April 1 through October 31) is Above 3,570 Feet | Percent of Months

    • Glen Canyon Dam Calendar Year Release | Average

  • The new robustness and vulnerability measures are:

    • Powell April 1 Pool Elevation

    • Powell October 1 Pool Elevation

    • Count of Months From April 1 to October 31 Where Powell Pool Elevation is Greater Than 3,570 Feet

    • Glen Canyon Dam Calendar Year Release

Explanatory Content:

• Added Spanish support to Combined Storage Discount Volume UI in Strategy Creation and Modification.

Version 1.27.2 Release Notes

Bug fixes:

• Sessions can now be uploaded when the app is in Spanish mode.

• Save Session

  • Invalid robustness/vulnerability metrics in a save session will now be recovered or replaced with the default definition.

• Hover effect has been removed from static tables on Strategy Creation & Modification, Performance, and Robustness.

• Some models with continuous curves for both release and reduction that used equal-contents equalization were incorrectly calculated with threshold-based equalization. Those models have been rerun and the data have been corrected.

• Units on Difference Between January 1 Mead Storage Percent Full and Total System* Storage Percent Full, Difference Between January 1 Powell Storage Percent Full and Total System* Storage Percent Full, and Difference Between January 1 Flaming Gorge + Blue Mesa + Navajo Storage Percent Full and Total System* Storage Percent Full have been updated to reflect "Difference in Percent".

• Performance

  • Parallel plot should no longer occasionally fail to render when visiting the performance tab.

  • Colormap now loads properly on initial performance load after loading a session from another tab.

  • Logic no longer runs on robustness and crashes the app.

• Fixed a crash on Performance when Spanish is the selected language.

• Vulnerability

  • Fixed a bug where single leaf trees caused the app to crash.

  • Warning about 0% frequency definition will only shown on 0% frequency selection.

  • The Choose Operational Strategy Dropdown on Vulnerability and Summary no longer populates with a single empty option, and when empty will show as empty.
    

Feature Development:

• Changed the sort order for the "Available Strategies" table to start with 5 sample strategies, followed by strategies ordered alphanumerically.

• Additional option for discounting volume has been added to Lower Basin combined storage concepts This includes: (Combined Storage, Tiered, Hydrology), (Combined Storage, Tiered, No Mod), (Combined Storage, Continuous, Hydrology), and (Combined Storage, Continuous, No Mod).

• Users will be notified with a toast when a strategy they have loaded into the PCM is a custom strategy.

• Added a "Select All" button to drop downs where it makes sense to have one.

• Performance improvements in Performance Trace View to load plots fasters.

• The UI for saving a session has been redesigned to accommodate the saving of partial sessions:

  • Trace view

    • Trace view input are now saved in saved sessions

  • Session filenames

    • Session filenames now append the included parts of the saved session, concatenated with `+` . Full sessions are appended with `full`

• Save Session Improvements

  • Session schema

    • The session schema has been revised to a structure that enables straightforward reasoning about it's contents.

  • Session Validation

    • Validation of non-conforming saved sessions has been improved. Save sessions with known warnings are now automatically recovered, with improved messaging for users.

  • Saved Performance

    • Data Filters are now applied immediately when a saved session with performance data is loaded from another tab and then visits performance

    • Trace view

      • The trace view UI is slightly more responsive and inputs now function independently of Tradeoff view after initial load.
