 ** SYS version 4.0
-USB initialization/finalization demarcation has been changed.
-Enabling/disabling USB module is done by USB driver.  SYS routines
-only handles USB cable config.  For all boards, USB driver doesn't use
-usb_lld_sys_init/usb_lld_sys_shutdown (those routines only makes sense
-for USB self powered situation, which Chopstx does not support yet).
+USB initialization/finalization API has been changed.  SYS routines

 ** USB driver change
 Enabling/disabling USB module is done by USB driver.  It's

 ** New board support: ST Nucleo-32 L432
 ST Nucleo-32 L432 is a small board with ST-Link/V2-1.
 
+** Minor implementation change: chopstx_claim_irq
+If the interrupt is disabled (possibly by chx_intr) when
+chopstx_claim_irq is called, INTR->ready is set to 1.  This allows
+calling chopstx_claim_irq after hardware initialization which may
+cause an interrupt before the call of chopstx_claim_irq.
