+```
+
+
+## description ##
+
+
+**jsx** is an erlang application for consuming, producing and manipulating 
+[json][json]
+
+**jsx** follows the json [spec][rfc4627] as closely as possible with allowances for
+real world usage
+
+**jsx** is pragmatic. the json spec allows extensions so **jsx** extends the spec in a
+number of ways. see the section on `strict` in [options](#option) below though
+
+json has no official comments but this parser allows c/c++ style comments. 
+anywhere whitespace is allowed you can insert comments (both `// ...` and `/* ... */`)
+
+some particularly irresponsible json emitters leave trailing commas at the end of
+objects or arrays. **jsx** allows a single trailing comma in input. multiple commas
+in any posistion or a preceding comma are still errors
+
+all **jsx** decoder input should be `utf8` encoded binaries. sometimes you get binaries
+that are almost but not quite valid utf8 whether due to improper escaping or poor
+encoding. **jsx** replaces invalid codepoints and poorly formed sequences with the 
+unicode replacement character (`u+FFFD`) but does it's best to return something
+comprehensible
+
+json only allows keys and strings to be delimited by double quotes (`u+0022`) but
+javascript allows them to be delimited by single quotes (`u+0027`) as well. **jsx**
+follows javascript in this. strings that start with single quotes can contain double
+quotes but must end with single quotes and must escape any single quotes they contain
+
+json and **jsx** only recognize escape sequences as outlined in the json spec. it just
+ignores bad escape sequences leaving them in strings unaltered
+
+
+### migrating from 1.x ###
+
+if you're migrating from jsx v1.x to v2.x in most cases you won't need to
+make any changes to your code
+
+support for encoding otp 17.0's new map type is now enabled by default when compiling
+via rebar for any release that supports them. jsx should still compile cleanly for
+earlier releases without any user intervention. if you'd like to disable maps you can
+either set the env variable `JSX_NOMAPS` or by uncommenting the applicable tuple in
+`rebar.config`
+
+if you used any of `replaced_bad_utf8`, `single_quoted_strings`, `comments`,
+`ignored_bad_escapes` or `relax` you can simply omit them from your calls to jsx,
+they are all enabled by default now. if you want stricter parsing see the new
+[`strict` options](#option) available
+
+if you were using jsx to parse partial json using it's streaming features it is now
+disabled by default. you'll need to pass the `stream` option to calls to jsx functions
+to reenable it
+
+support for `pre_encode` and `post_decode` has been removed. they were fragile and hard
+to understand and they prevented evolution of the encoding and decoding code
+
+

+see below                       | `datetime()`
+
+*   numbers
+
+    javascript and thus json represent all numeric values with floats. there's no
+    reason for erlang -- a language that supports arbitrarily large integers -- to
+    restrict all numbers to the ieee754 range
+    
+    whenever possible, **jsx** will interpret json numbers that look like integers as 
+    integers. other numbers will be converted  to erlang's floating point type, which
+    is nearly but not quite iee754. negative zero is not representable in erlang (zero
+    is unsigned in erlang and `0` is equivalent to `-0`) and will be interpreted as
+    regular zero. numbers not representable are beyond the concern of this implementation,
+    and will result in parsing errors
+
+    when converting from erlang to json, floats are represented with their 
+    shortest representation that will round trip without loss of precision. this 
+    means that some floats may be superficially dissimilar (although 
+    functionally equivalent). for example, `1.0000000000000001` will be 
+    represented by `1.0`
+
+*   strings
+
+    json strings must be unicode encoded binaries or erlang atoms. in practice,
+    because **jsx** only accepts `utf8` binaries all binary strings must be `utf8`.
+    in addition to being unicode json strings restrict a number of codepoints and
+    define a number of escape sequences
+
+    json string escapes of the form `\uXXXX` will be converted to their 
+    equivalent codepoints during parsing. this means control characters and 
+    other codepoints disallowed by the json spec may be encountered in resulting 
+    strings. the utf8 restriction means the surrogates are explicitly disallowed.
+    if a string contains escaped surrogates (`u+d800` to `u+dfff`) they are
+    interpreted but only when they form valid surrogate pairs. surrogates
+    encountered otherwise are replaced with the replacement codepoint (`u+fffd`)
+
+    all erlang strings are represented by **valid** `utf8` encoded binaries. the 
+    encoder will check strings for conformance. badly formed `utf8` sequences may
+    be replaced with the replacement codepoint (`u+fffd`) according to the unicode
+    spec
+
+    this implementation performs no normalization on strings beyond that 
+    detailed here. be careful when comparing strings as equivalent strings 
+    may have different `utf8` encodings
+
+*   true, false and null
+
+    the json primitives `true`, `false` and `null` are represented by the 
+    erlang atoms `true`, `false` and `null`. surprise
+
+*   arrays
+
+    json arrays are represented with erlang lists of json values as described 
+    in this section
+
+*   objects
+
+    json objects are represented by erlang proplists. json maps may also be
+    encoded to json and optionally decoded to maps (via the `return_maps`
+    option)
+    
+    the empty object has the special representation `[{}]` to differentiate it
+    from the empty list. ambiguities like `[true, false]` prevent the use of
+    the shorthand form of property lists using atoms as properties so all
+    properties must be tuples. all keys must be encoded as in `string` or as
+    atoms or integers (which will be escaped and converted to binaries for
+    presentation to handlers). values should be valid json values. repeated
+    keys are tolerated in json text decoded to erlang terms but are not allowed
+    in erlang terms encoded to json
+
+*   datetime
+
+    erlang datetime tuples (`{{Year, Month, Day}, {Hour, Min, Sec}}`) as returned
+    from `erlang:localtime/0` are automatically encoded as [iso8601][iso8601]
+    strings and are assumed to be UTC time. no conversion is attempted of json [iso8601][iso8601] strings in decoded json
+
+
+### incomplete input ###
+
+**jsx** can handle incomplete json texts. if the option `stream` is passed to the decoder
+or parser and if a partial json text is parsed, rather than returning a term from
+your callback handler, **jsx** returns `{incomplete, F}` where  `F` is a function with 
+an identical API to the anonymous fun returned from `decoder/3`, `encoder/3` or 
+`parser/3`. it retains the internal state of the  parser at the point where input
+was exhausted. this allows you to parse as you stream json over a socket or file 
+descriptor, or to parse large json texts without needing to keep them entirely in
+memory
+
+however, it is important to recognize that **jsx** is conservative by default. **jsx** will 
+not consider the parsing complete even when input is exhausted and the json text is
+unambiguously incomplete. to end parsing call the `incomplete` function with the
+argument `end_stream` (or `end_json`) like:
+
+```erlang
+1> {incomplete, F} = jsx:decode(<<"[">>, [stream]).
+{incomplete,#Fun<jsx_decoder.1.122947756>}
+2> F(end_stream).  % can also be `F(end_json)`
+** exception error: bad argument
+3> {incomplete, G} = F(<<"]">>).
+{incomplete,#Fun<jsx_decoder.1.122947756>}
+4> G(end_stream).  % can also be `G(end_json)`
+[]
+```
+
+
+## data types ##
+
+#### `json_term()` ####
+
+```erlang
+json_term() = [json_term()]
+    | [{binary() | atom() | integer(), json_term()}]
+    | #{} % map of any size, not just the empty map
+    | true
+    | false
+    | null
+    | integer()
+    | float()
+    | binary()
+    | atom()
+		| datetime()
+```
+
+the erlang representation of json. binaries should be `utf8` encoded, or close 
+at least
+
+#### `json_text()` ####
+
+```erlang
+json_text() = binary()
+```
+
+a utf8 encoded binary containing a json string
+
+#### `event()` ####
+
+```erlang
+event() = start_object
+    | end_object
+    | start_array
+    | end_array
+    | {key, binary()}
+    | {string, binary()}
+    | {integer, integer()}
+    | {float, float()}
+    | {literal, true}
+    | {literal, false}
+    | {literal, null}
+    | end_json
+```
+
+the subset of [`token()`](#token) emitted by the decoder and encoder to handlers
+
+#### `option()` ####
+
+```erlang
+option() = dirty_strings
+    | escaped_forward_slashes
+    | escaped_strings
+    | repeat_keys
+    | stream
+    | strict
+    | {strict, [strict_option()]}
+    | return_tail
+    | uescape
+    | unescaped_jsonp
+
+strict_option() = comments
+    | trailing_commas
+    | utf8
+    | single_quotes
+    | escapes
+``` 
+
+**jsx** functions all take a common set of options. not all flags have meaning 
+in all contexts, but they are always valid options. functions may have 
+additional options beyond these. see 
+[individual function documentation](#exports) for details
+
+- `dirty_strings`
+
+    json escaping is lossy; it mutates the json string and repeated application 
+    can result in unwanted behaviour. if your strings are already escaped (or 
+    you'd like to force invalid strings into "json" you monster) use this flag 
+    to bypass escaping. this can also be used to read in **really** invalid json 
+    strings. everything between unescaped quotes are passed as is to the resulting 
+    string term. note that this takes precedence over any other options
+
+- `escaped_forward_slashes`
+
+    json strings are escaped according to the json spec. this means forward 
+    slashes (solidus) are only escaped when this flag is present. otherwise they 
+    are left unescaped. you may want to use this if you are embedding json 
+    directly into a html or xml document
+
+- `escaped_strings`
+
+    by default both the encoder and decoder return strings as utf8 binaries 
+    appropriate for use in erlang. escape sequences that were present in decoded 
+    terms are converted into the appropriate codepoint while encoded terms are 
+    unaltered. this flag escapes strings as if for output in json, removing 
+    control codes and problematic codepoints and replacing them with the 
+    appropriate escapes
+
+- `stream`
+
+    see [incomplete input](#incomplete-input)
+
+- `strict`
+
+    as mentioned [earlier](#description), **jsx** is pragmatic. if you're more of a
+    json purist or you're really into bdsm stricter adherence to the spec is
+    possible. the following restrictions are available
+    
+    * `comments`
+    
+        comments are disabled and result in a `badarg` error
+    
+    * `trailing_commas`
+    
+        trailing commas in an object or list result in `badarg` errors
+    
+    * `utf8`
+    
+        invalid codepoints and malformed unicode result in `badarg` errors
+
+    * `single_quotes`
+    
+        only keys and strings delimited by double quotes (`u+0022`) are allowed. the
+        single quote (`u+0027`) results in a `badarg` error
+    
+    * `escapes`
+
+        escape sequences not adhering to the json spec result in a `badarg` error
+    
+    any combination of these can be passed to **jsx** by using `{strict, [strict_option()]}`.
+    `strict` is equivalent to `{strict, [comments, bad_utf8, single_quotes, escapes]}` 
+
+- `return_tail`
+
+    upon reaching the end of a valid json term in an input stream return the term and any
+    remaining bytes in the input stream as `{with_tail, term(), binary()}` where the second
+    member of the tuple is the json term and the third is any remaining bytes. note that
+    leading whitespace will be stripped from the tail
+
+- `uescape`
+
+    escape all codepoints outside the ascii range for 7 bit clean output. note
+    this escaping takes place even if no other string escaping is requested (via
+    `escaped_strings`)
+
+- `unescaped_jsonp`
+
+    javascript interpreters treat the codepoints `u+2028` and `u+2029` as 
+    significant whitespace. json strings that contain either of these codepoints 
+    will be parsed incorrectly by some javascript interpreters. by default, 
+    these codepoints are escaped (to `\u2028` and `\u2029`, respectively) to 
+    retain compatibility. this option simply removes that escaping
+
+
+## exports ##
+
+
+#### `encoder/3`, `decoder/3` & `parser/3` ####
+
+```erlang
+decoder(Module, Args, Opts) -> Fun((JSONText) -> any())
+encoder(Module, Args, Opts) -> Fun((JSONTerm) -> any())
+parser(Module, Args, Opts) -> Fun((Tokens) -> any())
+
+  Module = atom()
+  Args = any()
+  Opts = [option()]
+  JSONText = json_text()
+  JSONTerm = json_term()
+  Tokens = event() | [event()]
+```
+
+**jsx** is a json compiler with interleaved tokenizing, syntactic analysis and 
+semantic analysis stages. included are two tokenizers; one that handles json 
+texts (`decoder/3`) and one that handles erlang terms (`encoder/3`). there is 
+also an entry point to the syntactic analysis stage for use with user-defined 
+tokenizers (`parser/3`)
+
+all three functions return an anonymous function that takes the appropriate type 
+of input and returns the result of performing semantic analysis, the tuple 
+`{incomplete, F}` where `F` is a new anonymous function (see 
+[incomplete input](#incomplete_input)) or a `badarg` error exception if 
+syntactic analysis fails
+
+`Module` is the name of the callback module
+
+`Args` is any term that will be passed to `Module:init/1` prior to syntactic 
+analysis to produce an initial state
+
+`Opts` are detailed [here](#option)
+
+check out [callback module documentation](#callback_exports) for details of 
+the callback module interface
+
+#### `decode/1,2` ####
+
+```erlang
+decode(JSON) -> Term
+decode(JSON, Opts) -> Term
+
+  JSON = json_text()
+  Term = json_term()
+  Opts = [option() | labels | {labels, Label} | return_maps]
+    Label = binary | atom | existing_atom | attempt_atom
+    F = fun((any()) -> any())
+```
+
+`decode` parses a json text (a `utf8` encoded binary) and produces an erlang 
+term
+
+the option `labels` controls how keys are converted from json to
+erlang terms.  `binary` (the default behavior) does no conversion
+beyond normal escaping. `atom` converts keys to erlang atoms and
+results in a `badarg` error if the keys fall outside the range of erlang
+atoms. `existing_atom` is identical to `atom` except it will not add
+new atoms to the atom table and will result in a `badarg` error if the atom
+does not exist. `attempt_atom` will convert keys to atoms when they exist,
+and leave them as binary otherwise
+
+the option `return_maps` will attempt to return objects as maps instead of
+proplists. this option has no effect when used with releases that do not
+support maps
+
+raises a `badarg` error exception if input is not valid json
+
+
+#### `encode/1,2` ####
+
+```erlang
+encode(Term) -> JSON
+encode(Term, Opts) -> JSON
+
+  Term = json_term()
+  JSON = json_text()
+  Opts = [option() | space | {space, N} | indent | {indent, N}]
+    N = pos_integer()
+```
+
+`encode` converts an erlang term into json text (a `utf8` encoded binary)
+
+the option `{space, N}` inserts `N` spaces after every comma and colon in your 
+json output. `space` is an alias for `{space, 1}`. the default is `{space, 0}`
+
+the option `{indent, N}` inserts a newline and `N` spaces for each level of 
+indentation in your json output. note that this overrides spaces inserted after 
+a comma. `indent` is an alias for `{indent, 1}`. the default is `{indent, 0}`
+
+raises a `badarg` error exception if input is not a valid 
+[erlang representation of json](#json---erlang-mapping)
+
+
+#### `format/1,2` ####
+
+```erlang
+format(JSON) -> JSON
+format(JSON, Opts) -> JSON
+
+  JSON = json_text()
+  Opts = [option() | space | {space, N} | indent | {indent, N}]
+    N = pos_integer()
+```
+
+`format` parses a json text (a `utf8` encoded binary) and produces a new json 
+text according to the format rules specified by `Opts`
+
+the option `{space, N}` inserts `N` spaces after every comma and colon in your 
+json output. `space` is an alias for `{space, 1}`. the default is `{space, 0}`
+
+the option `{indent, N}` inserts a newline and `N` spaces for each level of 
+indentation in your json output. note that this overrides spaces inserted after 
+a comma. `indent` is an alias for `{indent, 1}`. the default is `{indent, 0}`
+
+raises a `badarg` error exception if input is not valid json
+
+
+#### `minify/1` ####
+
+```erlang
+minify(JSON) -> JSON
+
+  JSON = json_text()
+```
+
+`minify` parses a json text (a `utf8` encoded binary) and produces a new json 
+text stripped of whitespace
+
+raises a `badarg` error exception if input is not valid json
+
+
+#### `prettify/1` ####
+
+```erlang
+prettify(JSON) -> JSON
+
+  JSON = json_text()
+```
+
+`prettify` parses a json text (a `utf8` encoded binary) and produces a new json 
+text equivalent to `format(JSON, [{space, 1}, {indent, 2}])`
+
+raises a `badarg` error exception if input is not valid json
+
+
+#### `is_json/1,2` ####
+
+```erlang
+is_json(MaybeJSON) -> true | false
+is_json(MaybeJSON, Opts) -> true | false
+
+  MaybeJSON = any()
+  Opts = options()
+```
+
+returns true if input is a valid json text, false if not
+
+what exactly constitutes valid json may be [altered](#option)
+
+
+#### `is_term/1,2` ####
+
+```erlang
+is_term(MaybeJSON) -> true | false
+is_term(MaybeJSON, Opts) -> true | false
+
+  MaybeJSON = any()
+  Opts = options()
+```
+
+returns true if input is a valid erlang representation of json, false if not
+
+what exactly constitutes valid json may be altered via [options](#option)
+
+
+#### `maps_support/0` ####
+
+```erlang
+maps_support() -> true | false
+```
+
+if **jsx** was compiled with map support enabled returns `true`, else
+`false`
+
+
+## callback exports ##
+
+the following functions should be exported from a **jsx** callback module
+
+#### `Module:init/1` ####
+
+```erlang
+Module:init(Args) -> InitialState
+
+  Args = any()
+  InitialState = any()
+```
+
+whenever any of `encoder/3`, `decoder/3` or `parser/3` are called, this function 
+is called with the `Args` argument provided in the calling function to obtain 
+`InitialState`
+
+#### `Module:handle_event/2` ####
+
+```erlang
+Module:handle_event(Event, State) -> NewState
+
+  Event = [event()]
+  State = any()
+  NewState = any()
+```
+
+semantic analysis is performed by repeatedly calling `handle_event/2` with a 
+stream of events emitted by the tokenizer and the current state. the new state 
+returned is used as the input to the next call to `handle_event/2`. the 
+following events must be handled:
+
+-   `start_object`
+
+    the start of a json object
+
+-   `end_object`
+
+    the end of a json object
+
+-   `start_array`
+
+    the start of a json array
+
+-   `end_array`
+
+    the end of a json array
+
+-   `{string, binary()}`
+
+    a json string. it will usually be a `utf8` encoded binary. see the 
+    [options](#option) for possible exceptions. note that keys are also
+    json strings
+
+-   `{integer, integer()}`
+
+    an erlang integer (bignum)
+
+-   `{float, float()}`
+
+    an erlang float
+
+-   `{literal, true}`
+
+    the atom `true`
+
+-   `{literal, false}`
+
+    the atom `false`
+
+-   `{literal, null}`
+
+    the atom `null`
+
+-   `end_json`
+
+    this event is emitted when syntactic analysis is completed. you should 
+    do any cleanup and return the result of your semantic analysis

+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the

+
+   7. Disclaimer of Warranty. Unless required by applicable law or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,

+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# MessagePack Erlang
+
+![Travis](https://secure.travis-ci.org/msgpack/msgpack-erlang.png)
+
+![Drone.io](https://drone.io/github.com/msgpack/msgpack-erlang/status.png)
+
+## prequisites for runtime
+
+[Erlang/OTP](http://erlang.org/), >= R15B -- for older version, rebar won't work.
+Also based on [the new msgpack spec 232a0d](https://github.com/msgpack/msgpack/blob/232a0d14c6057000cc4a478f0dfbb5942ac54e9e/spec.md).
+
+## edit rebar.config to use in your application
+
+```erlang
+{deps, [
+  {msgpack, ".*",
+    {git, "git://github.com/msgpack/msgpack-erlang.git", "master"}}
+]}.
+```
+
+## Simple deserialization
+
+```erlang
+Ham = msgpack:pack(Spam),
+{ok, Spam} = msgpack:unpack(Ham).
+```
+
+## Stream deserialization
+
+```erlang
+{Term0, Rest0} = msgpack:unpack_stream(Binary),
+{Term1, Rest1} = msgpack:unpack_stream(Rest0),
+...
+```
+
+## String type
+
+Now this supports string type!
+
+```erlang
+Opt = [{enable_str, true}]
+{ok, "埼玉"} = msgpack:unpack(msgpack:pack("埼玉", Opt), Opt).
+ => {ok,[22524,29577]}
+```
+
+There are several options for `msgpack:pack/2` and `msgpack:unpack/2` .
+See `msgpack:options()` in `msgpack.hrl`.
+
+## Map Style
+
+Since Erlang/OTP 17.0
+
+```erlang
+msgpack:pack(#{ <<"key">> => <<"value">> }, [{format, map}]).
+```
+
+Or use old jiffy/jsx style
+
+```erlang
+msgpack:pack({[{<<"key">>, <<"value">>}]}, [{format, jiffy}]),
+msgpack:pack([{<<"key">>, <<"value">>}], [{format, jsx}]).
+```
+
+## Ext type
+
+Now msgpack-erlang supports ext type. Now you can serialize everything
+with your original (de)serializer. That will enable us to handle
+erlang- native types like `pid()`, `ref()` contained in `tuple()`. See
+`test/msgpack_ext_example_tests.erl` for example code.
+
+```erlang
+Packer = fun({ref, Ref}, Opt) when is_reference(Ref) -> {ok, {12, term_to_binary(Ref)}} end,
+Unpacker = fun(12, Bin) -> {ok, {ref, binary_to_term(Bin)}} end,
+Ref = make_ref(),
+Opt = [{ext,{Packer,Unpacker}}],
+{ok, {ref, Ref}} = msgpack:unpack(msgpack:pack({ref, Ref}, Opt), Opt).
+```
+
+This is still experimental feature, so I'm waiting for your feedback.
+
+## Compatibility mode
+
+To use as same with [old spec](https://github.com/msgpack/msgpack/blob/master/spec-old.md):
+
+```erlang
+OldHam = msgpack:pack(Spam, [{enable_str,false}]),
+{ok, Spam} = msgpack:unpack(OldHam, [{enable_str,false}]).
+```
+
+Since 0.2.3 now it's **false by default**.
+
+## Further tests
+
+See [msgpack-erlang-tests](http://github.com/kuenishi/msgpack-erlang-tests) for further tests
+
+## License

+
+# Release Notes
+
+## 0.3.3
+
+- Add OTP 17 series to Travis-CI tests
+- Fix wrong numbering for ext types
+- Allow packing maps even when {format,map} is not set
+- Fix Dialyzer invalid contract warning
+- Proper use of null for jiffy-style encoding/decoding
+
+## 0.3.2
+
+- set back default style as jiffy
+- fix bugs around nil/null handling
+
+## 0.3.0
+
+- supports map new in 17.0
+- jiffy-style maps will be deprecated in near future
+- set default style as map
+
+## 0.2.8
+
+0.2 series works with OTP 17.0, R16, R15, and with MessagePack's new
+and old format. But does not support `map` type introduced in
+OTP 17.0.
+
+It also supports JSX-compatible mode.
