Using Release Notes

Use release notes when upgrading to a newer version to learn about:

New features
Changes
Potential impact on your existing files and practices

Review the release notes for other MathWorks™ products required for this product (for example, MATLAB^® or Simulink^®). Determine if enhancements, bugs, or compatibility considerations in other products impact you.

If you are upgrading from a software version other than the most recent one, review the current release notes and all interim versions. For example, when you upgrade from V1.0 to V1.2, review the release notes for V1.1 and V1.2.

Undocumented Extras Library Blocks

All SimPowerSystems™ blocks have block mask descriptions and have been tested and validated. However, many blocks in the Extras library do not have block reference pages in the product documentation.

The Extras library blocks without block reference pages are listed below. The blocks shown in bold have corresponding continuous blocks that are documented. The rest of the blocks are undocumented.
