Since 1.10 is no longer listed on the firmware download page have are all of the changes in 1.10 been rolled into 1.11? From a support/documentation point (e.g. for a new end user not aware that 1.10 every existed) on the surface it appears that the changes made in v1.10 never existed since nothing between 1.01 and 1.11 shows up documented on the download page. Version 1.11 should at least make note that the following changes where also made since the release of 1.01.
