This is a bugfix release, no new features since 3.5.2 were added.


Compared to the latest release 3.5.2, the following changes and bugfixes were added.


Optimize Ditto internal pub/sub by adding subscribed for namespaces to topic

Issue #1894 described how to optimize the Ditto internal pub/sub mechanism to filter out even more events before publishing to a subscriber which would drop them.
When using the namespaces filter when subscribing for events in e.g. connections, the selected namespaces are now also part of the pub/sub topic which prevents unnecessary transmissions in the cluster.
PR #1900 provides this internal optimization.

Update deployment files and unit tests to use MongoDB 6.0

In PR #1897 all unit tests and deployment files were updated to use MongoDB 6.0.


This is a complete list of the merged pull requests.

UI: Fix that incoming thing updates always repeated the first entry

The UI contained a bug which caused that when “watching” changes of a selected thing, the “Incoming Thing Updates” list always repeated the first entry instead of correctly showing new entries.
This was fixed in PR #1901.

Ensure consistency when doing signal enrichment

When e.g. a Ditto connection published many events for a single thing in a short time and using signal enrichment, it was not guaranteed that the “enriched” data was from the same revision as the published event - leading to inconsistencies for things with high frequent updates.
This was reported in issue #1893 and fixed in PR #1904.

Fix time:now placeholder truncation

The in Ditto 3.5.0 added “truncation” for the time:now placeholder did not work in certain cases.
This was fixed via PR #1903.

Helm Chart

The Ditto Helm Chart contained some configuration bugs and enhancements which are also addressed with this bugfix release.

Added option to add custom annotations to podDeletionCostPatching jobs

In PR #1902 a new option to the Ditto Helm chart was added in order to specify custom annotations for the Helm chart jobs adding a “pod deletion cost” to Ditto k8s pods.
This e.g. is needed when running Ditto with Istio sidecars which would prevent the k8s jobs to finish.
