Version 0.1398.0 of Diego is recommended for use with CF v214.

Changes from 0.1353.0 to 0.1398.0:

This version of Diego pulls in over 2 months of major work on garden-linux. Major changes include the following:

• Port of wsh and wshd binaries from C to Go
• Garden-linux stores container layers in btrfs volumes
