Modular Configuration Directories
---------------------------------

CouchDB now loads configuration from the following places (`glob(7)`_ syntax)
in order:

- PREFIX/default.ini
- PREFIX/default.d/*
- PREFIX/local.ini
- PREFIX/local.d/*

The configuration options for `couchdb` script have changed to::

  -a FILE     add configuration FILE to chain
  -A DIR      add configuration DIR to chain
  -n          reset configuration file chain (including system default)
  -c          print configuration file chain and exit

Show and List API change
------------------------

Show and List functions must have a new structure in 0.10.
See `Formatting_with_Show_and_List`_ for details.

Stricter enforcing of reduciness in reduce-functions
----------------------------------------------------

Reduce functions are now required to reduce the number of values for a key.

View query reduce parameter strictness
--------------------------------------

CouchDB now considers the parameter ``reduce=false`` to be an error for queries
of map-only views, and responds with status code 400.
