The maintainers of the 40K Army Builder files have posted an updated version of the files.
From their website:
General release 1.06a now Available. Includes the 5E Tyranid file, our usual bug fixing and patching and something new – testing trial of Black Templars V2.
We would strongly urge anyone who is intending to use this file to put this release in an entirely new folder or to delete their older AB40K folder before applying this update. Many files have been removed and or modified and to prevent unnecessary problems with updating this is highly recommended.
Apocalypse formations based on the new Tyranid files have been adjusted. Note that there are a few formations which have options which are no longer available or do not fit in properly without interpretation. As it our “mission” to provide the data provided by GW without such interpretation, the offending data sheets were removed and will be restored whenever GW provides such guidelines to bring these older formations under the 5E Tyranid rules.
Witch Hunters and Daemonhunters ally rules have been substantially redone. Now they use the nominal system provided within AB for their selection instead of their own specialized procedure. Note that the nominal rules provided in each of those codices stll applies, only the way of selecting them within AB has changed.
