-## Opentrons Robot Software Changes in [!!EDIT ME WITH THE ACTUAL NUMBER OF THE NEXT RELEASE!!]
+## Opentrons Robot Software Changes in 7.2.0
 
-### HTTP API
+Welcome to the v7.2.0 release of the Opentrons robot software!
 
-- In the `/runs/commands`, `/maintenance_runs/commands`, and `/protocols` endpoints, the `dispense` command will now return an error if you try to dispense more than you've aspirated, instead of silently clamping.
-- The `/notifications/subscribe` WebSocket endpoint has been removed. See https://github.com/Opentrons/opentrons/pull/14280 for details.
-- The `/runs/commands` endpoints are significantly faster when you request a small number of commands from a stored run.
+This update may take longer than usual if your robot has a lot of long protocols and runs stored on it. Allow *approximately 20 minutes* for your robot to restart. This delay will only happen once.
 
-### Other Changes
+If you don't care about preserving your labware offsets and run history, you can avoid the delay by clearing your runs and protocols before starting this update. Go to **Robot Settings** > **Device Reset** and select **Clear protocol run history**.
+
+### Improved Features
 
-- The `notify_server` Python package has been removed. See https://github.com/Opentrons/opentrons/pull/14280 for details.
+- The robot software now runs Python 3.10. Many built-in Python packages were updated to match. If you have installed your own Python packages on the robot, re-install them to ensure compatibility.
+- Added error handling when dispensing. The `/runs/commands`, `/maintenance_runs/commands`, and `/protocols` HTTP API endpoints now return an error if you try to dispense more than you've aspirated.
+- Improved performance of the `/runs/commands` endpoints. They are now significantly faster when requesting a small number of commands from a stored run.
+
+### Bug Fixes
 
-### Upgrade Notes
+- The Flex Gripper will no longer pick up large labware that could collide with tips held by an adjoining pipette.
+- Flex now properly configures itself when connected by Ethernet directly to a computer.
 
-This update may take longer than usual if your robot has a lot of long protocols and runs stored on it. Allow **approximately 25 minutes** for your robot to restart. This delay will only happen once.
+### Removals
 
-If you don't care about preserving your labware offsets and run history, you can avoid the delay. Clear your runs and protocols before starting this update. Go to **Robot Settings** > **Device Reset** and select **Clear protocol run history**.
+- Removed the `notify_server` Python package and `/notifications/subscribe` WebSocket endpoint, as they were never fully used. (See pull request [#14280](https://github.com/Opentrons/opentrons/pull/14280) for details.)

+## Opentrons App Changes in 7.2.0
+
+Welcome to the v7.2.0 release of the Opentrons App!
+
+The Linux version of the Opentrons App now requires Ubuntu 20.04 or newer.
+
+### New Features
+
+- Added a warning in case you need to manually remove tips from a pipette after power cycling the robot.
+
+### Improved Features
+
+- Commands involving the trash bin or waste chute now appear in the run preview.
+- The app will prompt you to reanalyze protocols that haven't been analyzed in such a long time that intervening changes to the app could affect their behavior.
+
+### Bug Fixes
+
+- The OT-2 now accurately calculates the position of the Thermocycler. If you previously compensated for the incorrect position with labware offsets, re-run Labware Position Check to avoid pipette crashes.
