The changes in this beta will be available in the 4.13 production release, due out at the end of June 2020.
Changes in this release include
Performance Improvements for Editing and Saving
We have made changes to get significant performance improvements for editing and saving some large models. The Audit Log was causing one project to take 12minutes to save and that has been reduced down to 45 seconds.
We also found that editing performance significantly degraded after running some models. We found the issue and users with large models who found this issue should see a significant improvement when editing after a run.
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 have a go 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.
Resource Assessment Allocation table improvements
You can now freeze columns and drag columns to reorder the columns in the Allocation table within resource assessment:
Constituent Trend and % removal model
Links and Storages decay models have been extended to include:
Decay to a background concentration rather than to 0 and a % removal that can occur after the decay.
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:
Plugin Developers
We are planning on moving to C# 7, Visual Studio 2019 and .NET 4.8.0 soon, so you will need to make sure you have updated Visual Studio to continue developing plugins in the beta versions.
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).
