3.0

Breaking changes:

• The recursive operation now works slightly different (see 5ac1783)
• Queries with no matches will now return empty arrays, instead of false. The only exception being when using smart get and a non-divergent path, where false will still be returned.

New features:

• Support for child selector operation immediatly after recursive operation: $..[?(@.author == "Nigel Rees")]
• In|Not In Array Operation (#65 by @lucasangi)
• Added formal support for variable names starting with numbers in the dot-notation: $.2

2.1

• Allow filter keys with a regex match
  (#59)
• Allow PCRE i and x modifiers in regex expressions
  (#59)
• Fix bug causing a DivisionByZeroError when using negative indexes to access
  an empty array (#60)

2.0: Normalize behavior of .length operation

Until now (except for version 1.3, sorry, you should go to 1.3.1 if this affects you) .length operator always behaved in the smartGet manner.

Starting with this version, .length will behave as any other operator. That is, it will always return an array of results, even if there is just one, unless smartGet is enabled, then it'll work in the same way smartGet works for every other operation: return the result directly, if the path does not diverge, or return an array of results, if the path diverges.

Also, fix regex so that array interval selector of the type [:3] work.
