This change has, it seems, been brought forward a week - not sure why.

From the unofficial but incredibly comprehensive London Bus Routes
website:

149 - Contract retained by Arriva London with 36 new 10.4m DB300/
Gemini double deckers. Allocation transferred to Tottenham garage, but
8 buses will be outstationed at Leeside Road garage. New timetable
with Monday to Friday peak hour frequency increased to every 5 minutes
with two additional journeys in each peak and Monday to Saturday
daytime frequency reduced to every 8 minutes.

P.S. Irrelevant aside - bendy or bendie, bendys or bendies, bendybus
or bendibus? ('Artic' counts as a smart alec answer!)
