• New functionality

• Changes to existing functionality

When a new feature or change introduces a reported incompatibility between versions, the Compatibility Considerations subsection explains the impact.

Compatibility issues reported after the product is released appear under Bug Reports at the MathWorks Web site. Bug fixes can sometimes result in incompatibilities, so you should also review the fixed bugs in Bug Reports for any compatibility impact.

The MathWorks offers a user-searchable Bug Reports database so you can view Bug Reports. The development team updates this database at release time and as more information becomes available. This includes provisions for any known workarounds or file replacements. Information is available for bugs existing in or fixed in Release 14SP2 or later. Information is not available for all bugs in earlier releases.

Access Bug Reports using your MathWorks Account.

When MathWorks removes or replaces a function or function element (property or argument), we remove it in stages over multiple releases. This gradual process gives you time to adjust your code. The Functions and Function Elements Being Removed section lists an item if it enters a new stage of removal in the current release. Your release notes include actions to mitigate the effects.
