Not much, i.e., the commit logs are your best source of information
(well, ignoring source code ;-)..

commit e2f74005f548d90014cdf080802d455382e37cb9

    bgscan: Add signal strength change events
    
    This allows bgscan modules to use more information to decide on when
    to perform background scans. bgscan_simple can now change between
    short and long background scan intervals based on signal strength
    and in addition, it can trigger immediate scans when the signal
    strength is detected to be dropping.
    
    bgscan_simple takes following parameters now:
    short interval:signal strength threshold:long interval
    For example:
        bgscan="simple:30:-45:300"
