Anyone noticed the important changes on this revision especially the contingencies?
Careful reversing course in case of a diversion.

Interesting. Seems more codified than I recollect.
Now retired so, not that it matters to me, but:
Why 300' and not 500'?
Now retired so, not that it matters to me, but:
f) For deviations of greater than 10 NM, when the aircraft is approximately 10 NM from track,
initiate a level change of 300 ft.
If flying generally Eastbound (i.e. a magnetic track of 000° to 179°) and deviating left
(ie north) of track then descend 300 ft; if, however, deviating right (i.e. south) of track
then climb 300 ft.
If flying generally Westbound (i.e. a magnetic track of 180° to 359°) and deviating left
(i.e. south) of track then climb 300 ft; if, however, deviating right (i.e. north) of track
then descend 300 ft.

Almost HT, I would say because of the crossing tracks , if everybody diverts at same time ( i.e. due Wx ) on crossing you have someone 300ft down a FL , some opposite 300ft up their FL , so 400ft separation between them . Makes sense.

500' for other deviations requiring exiting tracks.
Must read the able vs unable to maintain altitude section carefully.
Also notice "should" vs must... I guess they wanted to give the PIC some leeway to be able to deviate from published procedure in case of fire/smoke etc..
