  History
 ⍝⍝ Contains information regarding the last release. A full history is available on GitHub. (This line is ignored)
-⍝ * 7.2.2
-⍝   * When an object was removed from the hit list then the message in the status bar was not changed accordingly.
-⍝   * When an object was removed from the hit via "Report Hits" then the context menu should not offer "Remove" again.
-⍝   * A "Hit report" windows should be closed automatically when the user hits either "Find" or "Replace".
-⍝   * A "Replace" operation should clear the hit list because it might well be outdated.
-⍝   * Information provided in the status bar improved.
-⍝ * 7.2.1
-⍝   * Bug fix: the "Search for" field lost its memory ot one stage.
+⍝ * 7.2.3
+⍝   * Bug fixes:
+⍝     * With commit from 2019-05-30 a serious bug was introduced regarding removing any items from the hit list.\\
+⍝       Rather than just removing the selected items the objects were also deleted from the workspace. However,
+⍝       acre was **not** told to delete them, so after re-opening the project everything was back again.
+⍝     * The assignment of a variable in a namespace script was ignored when on the same line a dfn was defined
+⍝       and the next function was a trad fun that carried the definition of a dfns.
 ⍝ \\

-## Ghostly namespaces
+## Anomalies
+
+### Scripted versus non-scripted namespaces
+
+Scripted namespace are in some ways an anomaly in Dyalog APL. For example, if there is a function `foo` in a namespace `NS` then the statement `NS.⎕EX 'foo'` deletes the function from an ordinary (non-scripted) namespace but _not_ from a scripted namespace, though it _is_ removed from the namespace that is connected to the script. `⎕FX` behaves similarly strange.
+
+Fire processes functions and operators in scripted namespaces in the same way as in ordinary namespaces. That means that a function that carries a hit is listed on its own in both cases. 
+
+A namespace script is _only_ listed in the hit list when it carries variable definitions or comments with hits.
+
+However, this is inconsistent with what Fire does with functions and operators: in ordinary namespaces a variable is listed on it's own only when its value --- not the name! --- carries a hit. For scripted namespaces it's listed on its own when the value _or_ the name carries a hit.
+
+The reason for this inconsistency is that is is very difficult for Fire to tell function assignments (like `fns←+/`) from variable assignments.
+
+Since "Replace" is only available for variables of certain types anyway, this seemed still the best way to deal with the problem.
+
+
+### Ghostly namespaces
 
 Note that Fire does not search ghostly namespaces. These are namespaces which exist together with GUI objects as well as classes. If you did not know about ghostly namespaces then it might be best to ignore them: they can be quite confusing.

 Note that strictly speaking this is the same thing: There is a GUI object called "MyForm" but there is also a ghostly namespace holding the "Hello" function. However, Dyalog APL perfectly keeps that as a secret: it has always been that way since GUI objects were introduced into Dyalog APL a long time ago, yet nobody ever realized this because Dyalog APL behaved in a way that makes that actually impossible.

+# Release Notes 7.2.3
+* Bug fixes:
+  * With commit from 2019-05-30 a serious bug was introduced regarding removing any items from the hit list.
+
+    Rather than just removing the selected items the objects were also deleted from the workspace. However, acre was **not** told to delete them, so after re-opening the project everything was back again.
+* The assignment of a variable in a namespace script was ignored when on the same line a dfn was defined and the next function was a trad fun that carried the definition of a dfns.
+

 # Release Notes 7.2.2
 * When an object was removed from the hit list then the message in the status bar was not changed accordingly.
 * When an object was removed from the hit via "Report Hits" then the context menu should not offer "Remove" again.
