Experience enhanced table loading and scrolling performance! Thanks to the newly-introduced Load Partially mode, data is now loaded in only visible rows. There is no longer a need to wait until data is calculated in the entire table. Additionally, fast scrolling has improved; it is now considerably smoother.

The import performance of data from an Excel or CSV file into the modeling tool adds a great experience while managing a large scope of data. The data import time using the table sync feature is significantly faster compared with the previous version (19.0 SP4). Also, the data import using the new Excel/CSV Import dialog is even better in comparison to Excel/CSV Sync feature. The import of 61k elements takes only 2 minutes (see the chart below).

Profiling Changes in the UML 2.5.1 Metamodel
Significant changes have been implemented in the UML metamodel for improved performance. The InstanceSpecifications, Slots, and ValueSpecifications are no longer used to store profiling data. Instead, new model element types and properties are introduced, while some have been removed (see the diagram below).
Image Removed
Profiling changes in the UML metamodel.
As shown in the figure above, Element references the TaggedValue that is used to specify the Boolean, Integer, Real, String, or Element values of the applied stereotype properties. This approach uses fewer model elements to store profiling data, which leads to a decrease in the total number of elements in SysML and UAF projects by 40-80%.
Note. Expressions based on the previously implemented profiling data storing metamodel no longer work, meaning that they have to be updated manually.
Project Merge has undergone considerable performance improvements. The modeling tool version 2021x requires approximately 4-5 times less memory to successfully merge two server project branches, compared to 19.0 SP4.

Furthermore, the merge operation speed has increased by 20-70% in 2021x compared to 19.0 SP4. Both frequent (between close project versions) and infrequent (between distant project versions) merges can now be performed much faster!

TWC Project Load
Project load memory and speed improvements have been implemented for Teamwork Cloud. The modeling tool now requires only 2GB of heap to load a 2M SysML project (first and second time) when working with TWC projects compared to 8GB in 19.0 SP4. Additionally, as a result of the UML metamodel changes, SysML projects are now opened 2-3 times faster.
Note. Received results cover the project load only, excluding validation, diagramming, and further modeling tool feature usage.

Three projects (sizes ranging from 1M to 2M) in 19.0 SP4 and the same projects in 2021x (sizes ranging from 750k to 1M) were used to run the tests.
Migration time is excluded because projects that had already been migrated were used for testing.
TWC Save to Local
In 2021x, great attention is paid to the memory consumption improvements. Saving a Teamwork Cloud project locally now requires less memory. For example, a 2M SysML project now consumes only 4GB of RAM, compared to 20GB in 19.0 SP4.

The development of the following plugins is discontinued:
Document Modeling Plugin (Model-based reports). For more effective model publishing and reviewing on the web, use Cameo Collaborator.
To create Views and Viewpoints diagrams using the modeling tool with no plugins installed, use the Cameo Collaborator Publisher plugin or the SysML plugin instead.
The DockBook Library Profile is no longer available.
Web portal reports are no longer available. For more effective model publishing and reviewing on the web, use Cameo Collaborator. You can also use Web Publisher (Simple HTML) or Web Publisher 2.0 ReportWizard templates to generate HTML reports.
WSDL Code Engineering and WSDL diagrams are no longer available.
C# Code Engineering and C# Professional Edition are no longer available.
CIL and CIL Disassembler Code Engineering are no longer available.
The News Reader (RSS) is no longer available. The notification at the right bottom corner of the modeling tool will inform you about the new version release instead.
The no_install_mac.zip and 32-bit installation files are no longer offered for download.
The Project Usage Map Profile is no longer available.
The JavaScript Nashorn is deprecated with the intention of removing it. We highly recommend using JavaScript Rhino instead.
The following 3rd party plugins are discontinued:
Cameo Workbench
Cameo Inter-Op
ParaMagic Lite
The following no cost plugins are no longer available in modeling tools:
Teamwork Server is no longer supported in the latest release. Teamwork Cloud should be used as a product for collaborative modeling and model version control. Customers still using Teamwork Server must migrate their server projects to TWC 19.0 series first and then upgrade to TWC 2021x.
You can now specify in the Environment Options dialog whether to compare only the direct or all the changes in diagrams during the Project Merge and Project Comparison operations. By default, only the changes made by the user in loaded (open) diagrams are analyzed, leaving out unintentional diagram changes that occurred due to indirect changes in the model. This feature not only eases both merge and project comparison processes for the user since the number of diagrams with changes is considerably reduced but also optimizes modeling tool performance.
An Environment option to specify the changes to detect in diagrams.
The model merge has undergone further usability improvements. From now on, changes from the Target and Equivalent Changes are automatically hidden by default, meaning that only the Source changes are shown. As a result, fewer changes need to be reviewed by the user.
What is more, the model merge has been extended by adding a capability to select which ancestor calculation algorithm to use. You now have the freedom to choose a Branch Point as an ancestor for your merges. This is especially useful in those cases when merge results become too complex to understand and analyze due to previously rejected changes. By default, Lowest Common Parent ancestor calculation algorithm is used.

With a significant improvement in report generations for large-scale MagicDraw projects, Report Wizard 2021x has now been equipped to more efficiently generate reports using Web Publisher 2.0 templates of projects, with less time required and supporting more elements than earlier versions of the product.
