With each new AutoCAD-based product release, retest your custom applications to ensure they work correctly before rolling out the latest release to all users.
Third-party applications might need to be repurchased and in-house custom .NET and ObjectARX applications might need to be recompiled when upgrading to the latest release. The changes to the AutoCAD application programming interfaces (APIs) varies from release to release with most major changes being aligned with the introduction of a new native drawing file format.
The following table lists the .NET and ObjectARX SDKs that are supported with the corresponding AutoCAD release.
