wking · Ma Shimiao · commit 53369f1e975d · 2016-08-18T17:51:56.000+08:00
The version field was added while 180df9d (Add runtime state configuration and structs, 2015-07-29, opencontainers#87) was in-flight [1], and it missed getting documented in the example. [1]: opencontainers#87 (comment) Signed-off-by: W. Trevor King <wking@tremily.us>
