What's new in ACP?

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 144:14 Aug 2024

Nodes stay highlighted when they are displayed in a Frame node part 2 (Build 143 added this for form nodes, this build adds for all nodes).
Fixed a bug with some Edit tables that are also a SubTable not showing in a frame node when clicked.
Turned off server side caching of the ACP page and the acpconfig.json file. Eliminates the need to do a hard refresh or clear the cache in order to see a new build (but if you leave the ACP page open in your browser you will need to refresh the browser or close and reopen it).
Added code to show multi line table headers.

Build 143:1 Aug 2024

The Hierarchical choice menus now work in ACP.
Form nodes stay highlighted while their value appears in a frame node.
You can enable models in ACP to show option "Download mode;\l" from the Close menu, using the flag save_menu_download:Prompt_to_download_free in save_menu_download AcpStyle. When selected, it shows a popup dialog with a download link and prompting to download ACP free. So that, if they dont have desktop Analytica installed, they can install and view your model on their PC.

Build 139: 24 June 2024

The main change in build 139 is a minor bug fix for certain arrows which don't display with the correct color.
There is some additional code for showing hierarchical choice menus in ACP, but since it is still incomplete, this code is turned off in Acpconfig.json on Lumina's servers for build 139

Build 138: 10 June 2024

Added a scroll bar for the object view in tall nodes if the contents don't fit the size of the node. (Frame nodes already showed a scroll bar in this case).
Fixed a bug with the object vie button not working if the node was a table with cells containing subtables.
Added code to show choice inputs' in the same font size as the other table text.
Added vertical and horizontal alignment AcpStyles for ACP Flex Boxes.
Added Flex_gap cps style for controlling the number of pixels between ACP Flex Box Items.
Added flex_wrap: wrap style with flex_direction: column. See ACP_Flexbox
Change the "display:flex" AcpStyle to be diagram/module level setting rather than a top level model setting. See ACP_Flexbox
Add 'Arial Narrow' to the list of Sans Serif fonts in acpConfig.json .
Embedded some common Google Fonts in ACP.
Added a list of recommended usable browsers to the Sign in page.
Add the functionality to Select multiple cells by clicking on cell and dragging cursor to end cells (as in Excel or Google sheets).

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.

- 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.

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.
Fixed a bug with some tall edit tables where the download csv button created a file with no data.

- Added the build number to the sign in page, with a link to this page. Also moved the build number to the acpconfig.json file

Build 127: 23 December 2023

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.

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.
