0.9.5

0.9.5 adds a line-wrapping character, fixes a few bugs, and improves our CI. The release has 77 commits from 8 contributors. Selected changes are below.

Look out for some conference talks coming up over the next few weeks, including QCon SF on Oct 2 and date2day on Oct 12.

Language:

• A new line-wrapping character, for lines that are long and we want to break up into multiple physical lines. This is slightly different from from many languages — it's on the subsequent line:

  from artists
  select is_europe =
  \ country == "DE"
  \ || country == "FR"
  \ || country == "ES"
  

  This allows for easily commenting out physical lines while maintaining a correct logical line; for example:

  from artists
  select is_europe =
  \ country == "DE"
  \ || country == "FR"
  \ || country == "FR"
  -\ || country == "ES"
  +#\ || country == "ES"
