We did it again: We raised the total hard limit for custom objects in an org to 3,000 (up from 2,500 in the previous release) so that you can install more custom objects from packages.
Where: This change applies to Lightning Experience and Salesforce Classic in all editions.
Why: Why not? You can do more with more objects. Each Salesforce edition has a limit on the number of custom objects that you can create in your org. Beyond the edition limit, a hard limit governs how many custom objects you can install from managed packages, such as apps publicly posted on AppExchange. The new 3,000 total limit includes the maximum number of custom objects created and installed in your org. For example, in Unlimited Edition, you can create up to 2,000 custom objects in your org. On top of that limit, you can also install up to 1,000 custom objects from managed packages. If your org is approaching the 3,000 total limit, we recommend that you hard delete or erase custom objects that you no longer need.
