For 3.24U and earlier, the forecast.ss entry for fleet allocation groups looked like:
# fleet assignment to allocation group (enter group ID# for each fleet, 0 for not included in an alloc group)
1 2
#_Conditional on >1 allocation group
.5 .5
Then for 3.24V, a user had a need to this to be year-specific, so the quick fix was to require that the allocation fraction be read for each year of the forecast:
#_Conditional on >1 allocation group
.5 .5 # 2017
.4 .6 # 2018
.4 .6 # 2019
So this breaks the I/O rule for changes and it should have been 3.25 as the release ID. But only a problem if N forecast years >1 and you use allocation groups.
3.30transition uses the 3.24V approach, so might crash when reading an older forecast.ss file.
