Examples in documentation for stable release are broken

[ikselven]

Beginning with chapter Array Indexing in the documentation of the stable release, nearly all output of example code in the documentation consists of errors. E.g. the first example of the mentioned chapter:

julia> ohlc[1]
ERROR: UndefVarError: ohlc not defined

julia> ohlc[1:3]
ERROR: UndefVarError: ohlc not defined

julia> ohlc[1:2:10]
ERROR: UndefVarError: ohlc not defined

julia> ohlc[[1:3;8]]
ERROR: UndefVarError: ohlc not defined

julia> ohlc[end]
ERROR: UndefVarError: ohlc not defined

Edit: Rewording of title and description, as originally the issue just concerned the above-mentioned chapter.

But I'm not sure how to re-trigger doc build of stable release.

The doc of dev branch looks fine.
