-- update to 0.10.0.0
-* Performance improvements:
- + Direct encoding via the new toEncoding method is over 2x faster than
toJSON.
- (You must write or code-gen a toEncoding implementation to unlock this
speedup.
- See below for details.)
- + Improved string decoding gives a 12% speed win in parsing
string-heavy JSON
- payloads (very common).
- + Encoding and decoding of time-related types are 10x faster (!!) as a
result of
- bypassing Data.Time.Format and the arbitrary-precision Integer type.
- + When using toEncoding, [Char] can be encoded without a conversion to
Text.
- This is fast and efficient.
- + Parsing into an Object is now 5% faster and more allocation-efficient.
-* SUBTLE API CHANGES, READ CAREFULLY:
- + With the exception of long-deprecated code, the API changes below
should be
- upwards compatible from older versions of aeson. If you run
into upgrade
- problems, please file an issue with details.
- + The ToJSON class has a new method, toEncoding, that allows direct
encoding
- from a Haskell value to a lazy bytestring without construction
of an
- intermediate Value.
- + The performance benefits of direct encoding are significant: more
than 2x
- faster than before, with less than 1/3 the memory usage.
- + To preserve API compatibility across upgrades from older versions of
this
- library, the default implementation of toEncoding uses toJSON.
You will not
- see any performance improvement unless you write an
implementation of
- toEncoding, which can be very simple:
- instance ToJSON Coord where
- toEncoding = genericToEncoding defaultOptions
- (Behind the scenes, the encode function uses toEncoding now, so
if you
- implement toEncoding for your types, you should see a speedup
immediately.)
- + If you use Template Haskell or GHC Generics to auto-generate your
ToJSON
- instances, you'll benefit from fast toEncoding implementations
for free!
- + When converting from a Value to a target Haskell type, FromJSON
instances now
- provide much better error messages, including a complete JSON
path from the
- root of the object to the offending element. This greatly
eases debugging.
- + It is now possible to use Template Haskell to generate FromJSON and
ToJSON
- instances for types in data families.
- + If you use Template Haskell or generics, and used to use the camelTo
function
- to rename fields, the new camelTo2 function is smarter. For
example, camelTo
- will rename CamelAPICase to camelapi_case (ugh!), while
camelTo2 will map
- it to camel_api_case (yay!).
- + New ToJSON and FromJSON instances for the following time-related
types: Day,
- LocalTime.
- + The Result type is now an instance of Foldable and Traversable.
- + The Data.Aeson.Generic module has been removed. It was deprecated in
late 2013.
- + The instance of Monad for the Result type lacked an implementation of
fail
- (oops). This has been corrected.
