+========================================================================
+Breaking: #81973 - FormEngineValidation.parseDate remove fixed year 2038
+========================================================================
+
+See :issue:`81973`
+
+Description
+===========
+
+In issue :issue:`81940` the TCA range upper bound was removed.
+But in the file ``typo3/sysext/backend/Resources/Public/JavaScript/FormEngineValidation.js`` in method
+:js:`FormEngineValidation.parseDate` a fixed year 2038 was included.
+
+The result: it was impossible to set a date after year 2038 in datetime fields.
+This limitation is now removed. The date is always set to the current date.
+
+A second problem: It was impossible to enter a date < 100 because there were magically added numbers: 2000 for values
+between 0 and 38 and 1900 for values between 39 and 100.
+
+
+Impact
+======
+
+The magic in calculating date values, e.g. entering 12 will result in 2012, is now removed.
+
+
+Affected Installations
+======================
+
+This affects only the behavior in backend record editing forms. Values of 0 to 100 will not be changed anymore.
+
+
+Migration
+=========
+
+No migration, this behavior was wrong and there is no migration possible.
