 # WIP Release Notes
 
-## v1.0.0-beta.6
-
-### Changed
-
-- The `data-on-load` callback is now delayed to the next microtask, making it possible to place the `data-indicator` attribute later on the same element.
+## v1.0.0-beta.7
 
 ### Fixed
 
-- Fixed a bug in which the `data-on-signals-change` attribute expression was not being executed when signal values changed ([#641](https://github.com/starfederation/datastar/issues/641)).
-- Fixed a bug in which the signal created by `data-ref` was being removed during the cleanup process ([#642](https://github.com/starfederation/datastar/issues/642)).
-- Fixed a bug in which errors were being caught in preact core, which was obfuscating the original error ([#643](https://github.com/starfederation/datastar/issues/643)).
-- Fixed a bug in which morphed DOM elements could lose their focus, due to a change of behavior in Idiomorph ([#645](https://github.com/starfederation/datastar/issues/645)).
+- Fixed a bug in which `datastar-remove-fragments` events were not having any effect ([#664](https://github.com/starfederation/datastar/issues/664)).
