Libbson-1.7.0

It is my pleasure to announce libbson 1.7.0.

• Changes to JSON encoding and decoding:
  • New functions bson_as_canonical_extended_json and
    bson_as_relaxed_extended_json convert BSON to canonical and relaxed
    extended JSON according to MongoDB Extended JSON Spec.
    Output for the existing bson_as_json function has not been changed.
  • When parsing JSON type wrappers like "$timestamp", any missing or extra
    keys are an error.
  • The JSON format for BSON regular expressions is now "$regularExpression":
    {"pattern": "...", "options": "..."}. The old format {"$regex": "...",
    "$options": "..."} is still parsed.
  • The JSON format for BSON binary elements is now "$binary": {"base64":
    "...", "subType": "..."}. The old format {"$binary": "...", "$type":
    "..."} is still parsed.
  • BSON dates can be parsed from "$date" as an ISO8601 date or "$numberLong"
    as milliseconds since the epoch: "t": {"$date": {"$numberLong": "1234"}}.
    Dates can no longer be formatted as raw integers. bson_as_json writes a
    BSON date after 1970 as "$date" with an ISO8601 string, and dates before
    1970 as negative milliseconds wrapped in "$numberLong".
    bson_as_canonical_extended_json always writes dates with "$numberLong".
    bson_as_relaxed_extended_json always writes dates with "$date".
  • The non-numbers NaN, Infinity, and -Infinity are now recognized (regardless
    of case) when parsing JSON.
• CMake build now installs .pc files for programs that link to libbson using
  pkg-config. Both the CMake and Autotools build systems now install .cmake
  files for programs that link to libbson using CMake. Linking to libbson
  statically or dynamically is now much more convenient.
• New CMake option, "ENABLE_STATIC", defaults to ON.
• Minimum required CMake version has been increased to 3.1.
• CMake remains experimental on non-Windows platforms and issues a warning now
• New functions
  • bson_strcasecmp, a portable equivalent of strcasecmp.
  • bson_iter_as_double, cast the current value to double.
  • bson_iter_init_from_data, creates an iterator from BSON string.
  • bson_validate_with_error, checks a document like bson_validate does but
    also reports which key was invalid
• New convenience macros
  • BSON_ITER_HOLDS_INT, checks if iterator holds int32 or int64
  • BSON_ITER_HOLDS_NUMBER, checks if iterator holds int32, int64 or double
• Raised BSON recursion limit to 200

Thanks to everyone who contributed to the development of this release.
