What's new in ACP?

<<Back to Analytica Cloud Platform

A list of improved features (and occasional bug fixes) of interest to most users by release date.

For a list of all changes to ACP, including ones of limited interest to most users, and changes between release builds, see this archive.

Build 135: 1 May 2024

  • The Analytica cube logo was flickering when displaying new results, or when pasting into edit tables. Added code to reduce this.
  • When a diagram had hidden nodes set to auto calculate, these nodes would show momentarily as they calculated causing a flickering effect on the diagram as it loaded. We changed this so that hidden nodes no longer show while calculating.
  • We are continuing to enhance edit tables to make the user experience closer to that in Excel and Google Docs.
    • Keyboard combo shift+ctrl+arrow key now selects the entire row or column.
    • Keyboard combo ctrl+arrow now moves the selected cell to the beginning or end of a row or column.
    • With multiple cells selected, arrow keys reselect to a single cell in the direction of the arrow key. as in Excel.
    • ACP now allows editing in the anchor cell with multiple cells selected, as in Excel.
  • For ACP servers using a load balancer on the front end. Added a periodic heartbeat message on the websocket so that the load balancer front end will not time out.


Build 133: 14 April 2024

  • When a diagram is loaded, any nodes that are set to auto-calculate will show results and will render - previously some nodes which were set to be non-visible would cause the diagram to apparently "flicker" as they were calculated. Code was added to prevent the non-visible nodes from causing this effect when loading diagrams.
  • An improvement to auto-scaling of slider inputs, if the scale changes after setting other inputs.
  • Added the ability to directly enter double quotes into an edit table cell after selecting with a single click.
  • Fixed a bug where a tall node that had it's node font changed (in Desktop Analytica) would not display in ACP.

Build 132: 3 April 2024

  • Added the ability to detect whether someone is using a mobile device and add a pop-up message informing them that the model may not appear the same as on a PC.
  • When you update a cell in ACP and hit enter, the cell in focus now goes to the next cell down, as in Excel and sheets.
  • Made table widths appear the same in ACP as in Desktop Analytica.
  • When editing a table cell, pressing tab moves the cell selection to the next cell to the right, as in Excel.
  • Turned off the sorting icon on some edit multitables where it doesn't work.

Build 131: 24 February 2024

  • Fixed a bug with wrong word wrapping in a text node title.
  • Changed Lumina.com links to analytica.com - just simplifying the web site.

    • More improvements to the fonts.
    • Changed the title of button "Email invite" to "Email invitation".
    • Tweaks to the heading of the Models Listing.
  • Made Arrow keys in edit tables work close to what you see with Excel.
    • Click on a cell (this is the "anchor" cell), then using arrow keys moves the selected cell e.g. a right arrow key moves the selected cell to the right.
    • Hold down the shift key and press an arrow keys. Expands (or contracts) the selected cell region.
    • Hold down the ctrl key and press arrow keys. E.g. Press right arrow key w/ ctrl key down. This moves the selected cell to the the end of the row.
    • Single-click to edit cell: When you click on a cell in sheets/excel you can just type to edit. In ACP you can now do the same.

Build 128: 8 January 2024

  • When ACP is computing and the cube is spinning, you can't click anything except the ‘Cancel’ button. Previously you could click on some other controls, sometimes causing conflicts.

  • When Analytica uses a font not available on the end-user's computer, it defaults to another similar font -- serif to another serif font, san-serif font to Arial or other san-serif font, and monospace font to a similar monospace font. Previously, a missing san-serif font usually defaulted to a serif font.
  • Copy and paste of a range of cells into an edit table, it now shows dashed lines around the range — to show it is working.

Earlier Builds

To see release notes for earlier builds of ACP.

ACP Sessions and Calculation

For now, there is:

  • 8 GB limit on RAM per model run (unlimited paged memory) on the Analytica ACP server..
  • no time limit on computations. It's possible that a very long computation could cause ACP to become unresponsive. In ACP1 computations were limited to 60 seconds in Individual accounts.
  • Some evaluation time warnings are not shown in the browser. For instance if you show a table with an invalid result.
