Items: the Housing and the unpaired Connector, checked against the source Holding a Housing fills the recipe book; JEI and EMI list everything from the start. An unpaired Connector places and says so rather than being refused (ConnectorBlock#setPlacedBy). Every page is now LF, as the source is.
Checked against the source Multiblock parts are in the refusal table and the "no multiblock check" line is gone; the bay that grows before a machine is refused is described; there are four screens; the Impeller sentence carries x4 and x16; Eye of Ender; the performance numbers live on Machines and Bays and the other pages link there; Recipes and Upgrades is merged into Items; the false "master is protected" line is gone.
