1.0+beta12 (18/08/2017)

• Fix the quoting of FLG lines in generated .merlin files (#200,
  Marcello Seri)

• Use the full path of archive files when linking. Before jbuilder
  would do: -I <path> file.cmxa, now it does -I <path> <path>/file.cmxa. Fixes #118 and #177

• Use an absolute path for ppx drivers in .merlin files. Merlin
  <3.0.0 used to run ppx commands from the directory where the
  .merlin was present but this is no longer the case

• Allow to use jbuilder install in contexts other than opam; if
  ocamlfind is present in the PATH and the user didn't pass
  --prefix or --libdir explicitly, use the output of ocamlfind printconf destdir as destination directory for library files (#179,
  Francois Bobot)

• Allow (:include ...) forms in all *flags fields (#153, David
  Allsopp)

• Add a utop subsommand. Running jbuilder utop in a directory
  builds and executes a custom utop toplevel with all libraries
  defined in the current directory (#183, Rudi Grinberg)

• Do not accept per_file anymore in preprocess field. per_file
  was renamed per_module and it is planned to reuse per_file for
  another purpose

• Warn when a file is both present in the source tree and generated by
  a rule. Before, jbuilder would silently ignore the rule. One now has
  to add a field (fallback) to custom rules to keep the current
  behavior (#218)

• Get rid of the deprecated-ppx-method findlib package for ppx
  rewriters (#222, fixes #163)

• Use digests (MD5) of files contents to detect changes rather than
  just looking at the timestamps. We still use timestamps to avoid
  recomputing digests. The performance difference is negligible and we
  avoid more useless recompilations, especially when switching branches
  for instance (#209, fixes #158)
