# Upgrade Notes
|
||
|
|
|
||
|
|
## 2024.9.0
|
||
|
|
|
||
|
|
### Following Feed
|
||
|
|
|
||
|
|
When upgrading an existing instance to version 2024.9.0, the Following Feed will initially be empty.
|
||
|
|
The feed will gradually fill as new posts federate, but it may be desirable to back-fill the feed with existing data.
|
||
|
|
This database script will populate the feed with the latest post of each type for all users, ensuring that data is fully populated after the update.
|
||
|
|
Run this after migrations but before starting the instance.
|
||
|
|
Warning: the script may take a long time to execute!

```postgresql
|
||
|
|
INSERT INTO latest_note (user_id, note_id, is_public, is_reply, is_quote)
|

|
|

|
|
"userId" as user_id,
|
||
|

|
||
|
|
ON CONFLICT DO NOTHING; -- Any conflicts are guaranteed to be older notes that we can ignore.
