# Upgrade Notes # Upgrade Notes
## 2024.10.0
### Hellspawns
Sharkey versions before 2024.10 suffered from a bug in the "Mark instance as NSFW" feature.
When a user from such an instance boosted a note, the boost would be converted to a hellspawn (pure renote with Content Warning).
Hellspawns are buggy and do not properly federate, so it may be desirable to correct any that already exist in the database.
The following script will correct any local or remote hellspawns in the database.
```postgresql
/* Remove "instance is marked as NSFW" hellspawns */
UPDATE "note"
SET "cw" = null
WHERE
"renoteId" IS NOT NULL
AND "text" IS NULL
AND "cw" = 'Instance is marked as NSFW'
AND "replyId" IS NULL
AND "hasPoll" = false
AND "fileIds" = '{}';
/* Fix legacy / user-created hellspawns */
UPDATE "note"
SET "text" = '.'
WHERE
"renoteId" IS NOT NULL
AND "text" IS NULL
AND "cw" IS NOT NULL
AND "replyId" IS NULL
AND "hasPoll" = false
AND "fileIds" = '{}';
```
