A new version of MISP ([2.4.130](https://github.com/MISP/MISP/tree/v2.4.130)) has been released with performance improvements, multiple bugs fixed and new features.
# Speed improvements
- [internal] cache tags instead of loading them over and over via the
event fetcher, fixes #6201.
- should speed things up for exports of datasets that have a lot of recurring tags
- moved the caching of some internals to the appmodel level to make it more generic
- [internal] Update correlations in one query.
Before, for every event saving action, four queries for updating correlations were generated
- [correlations] Faster loading related attributes.
- [sync] drop the republishing of events when the modification is merely
a timestamp bump.
- due to an already fixed issue still lingering, invalid event edits keep getting synchronised between instances
- these events still generate publish alerts erroneously
- this fix compares the previous state of the event to the modification, if there are no material changes (attributes, objects, object relations, event tags added/updated) then the publishing is dropped.
# API improvements
- Allow tag deletion for an event on update
- Allow for attribute tag deletion via Event or Attribute edit. Clean and return the attribute tags on response from editing an attribute, update code to remove legacy
