First have released the new timetable for the X5, which will apply from 11th January. It will no longer serve Kenn, Yatton or Congresbury but is extended beyond Cribbs Causeway to Bristol Parkway Station and UWE Frenchay Campus.
See the new X5 timetable here.
Carmel 88 also has a new timetable, from 12th January. See it here. It is extended beyond Clevedon to Yatton, replacing that part of the current X5. It will stop right outside Yatton Railway Station, giving Portishead's bus users a new way to connect with the rail network.
