IRRd 4.0.5 was released on September 2nd, 2019, and fixes
two bugs.
4.0.5.post1 was released due to an incorrect version
number change in 4.0.5, which could cause confusion
on which version was running.
In earlier versions of IRRd, queries that looked up
the routes originating from a certain AS,
did not correctly filter for the selected sources[1].
Also, the !s-lc query did not always correctly display
which sources were currently selected.
