+* Issue **#4211** : Prevent stream status in processing filters.
+
+
+```sh
+# ********************************************************************************
+# Issue title: Should we allow Proc Filters that use `Status`
+# Issue link:  https://github.com/gchq/stroom/issues/4211
+# ********************************************************************************
+
+# ONLY the top line will be included as a change entry in the CHANGELOG.
+# The entry should be in GitHub flavour markdown and should be written on a SINGLE
+# line with no hard breaks. You can have multiple change files for a single GitHub issue.
+# The  entry should be written in the imperative mood, i.e. 'Fix nasty bug' rather than
+# 'Fixed nasty bug'.
+#
+# Examples of acceptable entries are:
+#
+#
+# * Issue **123** : Fix bug with an associated GitHub issue in this repository
+#
+# * Issue **namespace/other-repo#456** : Fix bug with an associated GitHub issue in another repository
+#
+# * Fix bug with no associated GitHub issue.
