+# MISP 2.4.129 released
+
+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
+- [opendata export] Parsing portal url parameter + slight parameters
+  parsing changes.
+  - As the possibility of specifying the url of the
+    Open data portal to use instead of the default
+    one, we support here this parameter and adapt
+    the way we build the command that will launch
+    the python script
+  - Slight changes to replace some isset tests by
+    empty tests to make sure the concerned fields
+    are not only set, but also contain a value
+
+# Improvements
+
+- [UI] Show event preview when merging.
+- [attribute] Add support for IDN domains.
+- New: [freetext] Convert `[at]` to `@` and `hxtp` and `htxp` to `http`
+- [widgets] Additional widgets for sharing statistics and layouts.
+- [CLI] Allow to fetch remove event by UUID.
+- [stix import] Fixed port in ip-port objects import to lose src and dst
+  context.
+- [stix export] Fixed the slight difference between parsing x509
+  fingerprint attributes and x509 objects.
+- [stix export] Fixed x509 fingerprint attributes export & moved mapping
+  dictionaries to the mapping script
+  - Only the x509-fingerprint-sha1 attribute was
+    exported, and as a standard sha1 attribute,
+    which was a loss of context, now the x509
+    fingerprint attributes (md5, sha1 & sha256) are
+    exported as expected within a x509 observable
+  - Also moved the mapping dictionaries with the
+    appropriate indent to the mapping script, where
+    they should belong
+
+# Many bugs fixed and small improvements
