@ -22,6 +22,21 @@ should also be read to understand what has changed since earlier releases:
## Changes made on the 7.0 branch since 7.0.8.1
### Allow users to delete previously created records from the database
From this release, record instances and aliases that have already been loaded
by an IOC can be removed from the database again before the call to iocInit
by loading a second instance of the named records but using `"#"` in place of
the record type. Values for the fields are not required or advised, just use
an empty record body { }. This is useful when a template defines records that
are not wanted in some IOCs, without having to split or duplicate the original
template.
For example this will remove the record named "unwanted":
```
record("#", "unwanted") { }
```
