     Releases
 ======================
 
+tmt-1.38.0
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``tmt reportportal`` plugin has newly introduced size limit
+for logs uploaded to ReportPortal because large logs decreases
+ReportPortal UI usability. Default limit are 1 MB for a test
+output and 100 kB for a traceback (error log).
+Limits can be controlled using the newly introduced
+``reportportal`` plugin options ``-log-size-limit`` and
+``--traceback-size-limit`` or the respective environment
+variables.
