compressedLog and compressTrace are cached, but they are directly calculated from articulatedLog and articulatedTrace.
compressedTx is not cached in Transaction due to a special case in GoMaker which is now removed. compressedTx is cached for Slurp, but slurp wasn't being cached, so not a problem to simply remove it.
Upshot: before going to version 3.0.0, remove compressedLog and compressedTrace from the thing.
Use the upgrades field in the fields.csv file, but we need a "removed" type.
