What is happening to Route 8?

London Bus Route 8, as many are aware, has recently all of a sudden been changed here and there for some unexplained reason.

Route 8 has been shortened at both of its terminus ends.

Route 8 seems to no longer display 'Bow Church' as its destination and instead curtails to 'Old Ford', I am guessing this is due to the section that the 8 serves between Old Ford & Bow via the A12, yet I see no problem in that vicinity as Route 339 (Leytonstone-Shadwell) uses the same section of the A12 that the Route 8 does, so i'm guessing the problem isn't there.

Also Route 8 seems to be curtailed to Tottenham Court Road Station, instead of stopping all the way to Oxford Circus, Holles Street, yet it is not a permanent withdraw of the route as the bus stops along the section of Oxford Street between Tottenham Court Road & Oxford Circus, still display the number, instead with a red X over it, if anyone has an answer to this please let me know.
