 # Add changes at the top of the list. Keep it in ASCII, and 80-char wide.
 # Do not insert empty lines here, update check depends on it.
+  - changed: YAMAHA_BD: added HTTP request queue, send only one request at the
+             same time. This increases command reliability and response behaviour of 
+             the player.
   - changed: 55_GDS.pm: provide gdsAlertsHeadlines() instead of gdsHeadlines
   - feature: TelegramBot: multiple enhancements and fixes V1.1
                 keyboards on favorites and last command
