## Hiera 1.2.0 Release Notes ##
========================
# Features

Add deep-merge feature to backend lookups

    - Config option :merge_behavior => :native|:deep|:deeper
    - Add optional requirement on deep_merge gem to support
      :deep and :deeper options
    - Update Yaml backend to use Backend.merge_answer
    - Update Json backend to use Backend.merge_answer

(#16644) Add a generic file cache

    Add a general file cacher in Hiera::Filecache based on the work that was
    done in the YAML backend.

    Adjust the YAML and JSON backends to use this cache

(#18718) Create logger to handle fallback

    Sometimes a logger has been configured, but is not suitable for being
    used. An example of this is when the puppet logger has been configured,
    but hiera is not being used inside puppet. This adds a FallbackLogger
    that will choose among the provided loggers for one that is suitable.

# Bug Fixes

(#17434) Detect loops in recursive lookup

    The recursive lookup functionality was vulnerable to infinite recursion
    when the values ended up referring to each other. This keeps track of
    the names that have been seen in order to stop a loop from occuring. The
    behavior for this was extracted to a class so that it didn't clutter the
    logic of variable interpolation. The extracted class also specifically
    pushes and pops on an internal array in order to limit the amount of
    garbage created during these operations. This modification should be
    safe so long a new Hiera::RecursiveLookup is used for every parse that
    is done and it doesn't get shared in any manner.

(#17434) Support recursive interpolation

    The original code for interpolation had, hidden somewhere in its depths,
    supported recursive expansion of interpolations. This adds that support
    back in.
