The changes in this beta will be available in the Source version 5 production release, due out at the end of June 2020.

Changes in this release include:

performance improvements when editing and saving,
significant River Operations changes,
more work on results streaming,
custom chart improvements, and
Resource Assessment Allocation Table interface improvements.

Performance Improvements for Editing and Saving

We have made changes to significantly improve performance for editing and saving in some large models. The Audit Log was causing one project to take 12 minutes to save, this has been reduced to 45 seconds.

We also found that editing performance significantly deteriorated after running some models. We identified and resolved the issue, users with large models who were experiencing this problem should see a significant improvement when editing after a run.

River Operations Changes

The Operations tabular editor is now independent of the recording selection. You no longer get all recorders in the tabular editor. Recorders are now selected using the new column editor:

The tree on the left has also had major changes:

Results Streaming

Results can now be streamed to files on disk rather than stored in memory. This is to prevent memory issues with large runs. Results streaming is off by default, however, it can be turned on in Project Options:

The format used (called Source Time Series Database .sdb) is now also available as a general timeseries format.

Please test it out and let us know if you have any issues.

Custom Chart Improvements

We have included a search bar and more menu items under right-click.

Constituent Trend and % removal model

Links and Storages decay models have been extended to include a decay to a background concentration rather than to 0 and a % removal that can occur after the decay.

Resource Assessment Allocation table interface improvements

You can now freeze columns and drag columns to reorder the columns in the Allocation table within resource assessment:

Plugin Developers

We have moved to .NET 4.8 and are looking at moving to the new .csproj format on our journey to .net core. Once we complete this we may need to upgrade to Visual Studio 2019.

Regression Testing

We have removed the tolerance in our regression tests to help find issues earlier if we get different results on different machines or versions of operating systems.

Regression test repository changes since the first Source 4.12.2beta:

03 Project results updated

01 Project had function timings modified to give consistant results

Details here: 4.12.3 Regression Test Changes

Insight

To run Insight, you also need to install the 32bit version of Microsoft Visual C++ 2010 Redistributable Package.
This installer is for both 32bit machines and 64bit machines since the library we use is 32bit: Microsoft Visual C++ 2010 Redistributable Package (x86).
