Appsmith 2.1 Is Here: Ask AI, Security Updates, and an Important Upgrade Notice

Appsmith 2.1 is now available, and this release is an important one.

Across Appsmith 2.0 and 2.1, we’ve shipped new AI capabilities, major platform upgrades, and several important security improvements.  It’s highly recommended that you upgrade to 2.1 to address several Critical and High vulnerabilities.  If you manage a self-hosted Appsmith instance, please read the upgrade note below before moving to 2.x.

TL;DR

• Current Release: Appsmith 2.1 is now live.

• Ask AI: Appsmith 2.0 introduced Ask AI support.

• Security: 2.1 includes important security hardening updates.

• Upgrade Path: Self-hosted users upgrading from earlier than v1.96 must upgrade to v1.99 first.

• Platform Updates: Appsmith 2.x includes major underlying platform upgrades, including MongoDB 7.

• Recommendation: We recommend all self-hosted customers plan their upgrade carefully.

⚠️ Important Upgrade Notice

Before upgrading to Appsmith 2.0 or later, please check your current version.

If you are currently running a version earlier than v1.96, you must first upgrade to v1.99 before upgrading to Appsmith 2.0 or 2.1.

Appsmith 2.0 includes MongoDB 7, and the migration changes needed for that upgrade path are included in versions v1.96 through v1.99.

Skipping the v1.99 step will cause the upgrade to 2.x to fail -  including deployments that use an external MongoDB instance.

If you already attempted the upgrade and run into an issue, don’t panic. There is no data loss or destructive changes. Simply, upgrade to v1.99 first, confirm your instance is running successfully, and then continue to Appsmith 2.1.
