Released on: February 12, 2021Planned release: end of 2020
This release brings significant performance and scalability upgrades in key product areas: Merge, Teamwork Cloud project load, Teamwork Cloud project saving, table loading, Excel and CSV files import, and such common modeling tool operations as Copy/Paste, Find, Numbering, Element Selection, and Validation.
Version 2021x adds the ability to use layers in diagrams, automatically create legends, present diagrams or predefined sequences of diagrams in full screen to stakeholders, create compositions and aggregations in matrices, and use predefined element type filters when searching for the necessary model elements. Additionally, the Excel/CSV file import functionality has been reviewed and refreshed, and numerous improvements to Excel/CSV synchronization functionality in tables have been added.
Last but not least, project merge has been extended to give users the option to show only the changes in directly modified diagrams, hide Target and Equivalent Changes by default, and choose a specific ancestor calculation algorithm depending on merge scenario and expected outcome.

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).

Common Operations
Copy/Paste. Now you can copy and paste data 2-4 times faster depending on the specific scenario.

Find. The search speed in all texts has increased by 70-150% compared to 19.0 SP4.

Numbering. Creating the first numbered element, copying/pasting numbered elements, renumbering elements recursively, and updating the last element ID is now 30-840 times faster.

Element Selection. Now you can search and select the needed elements (e.g., in the Select Element and Quick Find dialogs as well as drop-down lists) approximately 40-50 times faster.

Validation. The active validation of the model now takes less than a second (0.8s after 5M project load and 0.5s after diagram load).

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).
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. Modeling The modeling tool version 20.0 requires 3-4 2021x requires approximately 4-5 times less memory to successfully merge two server project branches, compared to 19.0 SP4.

TWC Project
Load Memory and Speed Improvements
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 changesmostly, SysML projects are now opened 2-3 times faster.
NNote.B Received results cover the project load only, excluding validation, diagramming, and further modeling tool feature usage.

Three
3 projects (sizes ranging from 1M to 2M) in 19.0 SP4 and 3 the same projects in 20.0 2021x (sizes ranging from 750k to 1M) were used to run the tests.
Migration time is excluded because projects that had already been migrated projects were used for testing.
TWC
Disk Footprint Improvements
Major TWC disk footprint-related changes are presented in this release. TWC 20.0 requires twice as less disk space for the same amount of projects with no history compared to TWC 19.0 SP4. In addition to this achievement, the disk size growth is cut nearly 5 times in TWC 20.0 compared to TWC 19.0 SP4 for those projects users work actively on.

A database of 50 projects with 200 commits each was used to run the tests.
Project sizes ranged between 400k and 2.2M elements (average project size being 700k elements).
Partial Data Loading in Tables

Save to Local
In 2021x, great attention is paid to the memory consumption and speed 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. What is more, the reduced project element count allows the save to local operation to be finished nearly two times faster.

Diagrams can get extremely crowded as the model evolves. Therefore, highlighting a chosen piece of information, for example, only one specific aspect of the system becomes a great challenge. For your convenience, you can now filter diagrams by the selected Legend items to make only the necessary diagram layers stand out.

Do you feel that Legend creation is a tiresome activity? Not at all! From now on, you can create Legends more easily than ever before: extract them automatically from the elements displayed on your diagram instead of relying on a manual creation. Additionally, you can now automatically extract Legend items for the existing Legends. Once the Legend items are created, you can customize their adornments representation. They can now be displayed as rectangular shapes or extended lines to represent paths and shapes in greater detail.

You can import data from an Excel/CSV file directly to the model without installing Excel and CSV Import Plugins (read more about discontinued products). From now on, the newly created Excel/CSV Import dialog brings an easy to use and clearly understandable graphical user interface. It allows you to import content with just a few clicks by selecting the Excel/CSV file and specifying element mapping options. Additionally, you can save your maps to reuse them, collect saved maps in groups, manage those groups, and use an entire group instead of a single map for data import.

Three improvements to synchronize data between Excel or CSV files and a model:
Unique elements. Elements to be synchronized can now be identified not only by their name, but also by element property or tag value.
Direct relationships. From now on, you can import direct relationships between the source and target elements as easily as other elements.
Relationship ends. When importing relationships between different elements, you can select a specific property or tag to identify the source and target end of the relationship.

Detecting Changes in Diagrams During Merge
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.

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.

Additionally, 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 when merge results become too complex to understand and analyze due to previously rejected changes. By default, the Lowest Common Parent ancestor calculation algorithm is used.
