0.37 13 Jun 2018
 - Big refactor of all result handling for all services
 - Support for credential_process in credential handlers
   https://docs.aws.amazon.com/cli/latest/topic/config-vars.html#sourcing-credentials-from-external-processes
 - Better docu generation (osoriano)
 - Documentation update: Now POD contains links from the botocore documentation in services and methods
 - Bump XML::Simple dependency to 2.21 (mla)
 - Documentation improvement: Link back to Service class from method parameters classes (castaway)
 - Documentation improvement: New way of rendering parameters to methods (avoids very long method signatures in TOCs). This
   also fixes the fact that search.cpan.org didn't like very long lines in its TOC, so was not putting some methods in the
   TOC (castaway)
 - Documentation improvement: Synopsis for methods now has relevant examples for each method call with hints about the size of parameters, if they're optional, etc. (castaway)
 - Json services will now return the code of the exception as the message of the exception if no message was found (instead
   of 'unrecognized error format')
 - Some services were signing requests with the incorrect strings. Pricing, Opsworks, MarketplaceMetering, MarketplaceEntitlement,
   MarketplaceCommerceAnalytics, DynamoDBStreams, CloudHSMv2, ApplicationAutoScaling and AutoScalingPlans now sign correctly. (autarch)

0.33 04 Jun 2017
 - New Credential provider: Paws::Credential::Explicit for providing in-code credentials (meis)
 - Bug fixed: ETag not defined when using MojoAsyncCaller (PopeFelix)
 - New parameter for services: "endpoint" that is used to override the URL for sending requests 
   to a service
 - Breaking change: endpoints for services are calculated immediately when you invoke ->service.
   before they were calculated when the first method call to the service was made, so you got
   "no region" exceptions on the first call. Now the exceptions are thrown immediately.
 - Bug fixed: Paginators not working correctly in non-callback mode (SeptamusNonovant. Issue #146)
 - Bug fixed: Throw exceptions on methods that don't return anything
 - Bug fixed: Handle plain values in RestXML services, like S3s' PutBucketPolicy (sven-schubert)
 - Bug fixed: Some global services (f.ex: Route53, CloudFront) where forcing the user to specify
   a region. No need to pass region anymore) (Issue #113)

 - Remove under work warning from JSON-REST services: ApiGateway,CloudSearchDomain,CognitoSync,
   EFS, ES, ElasticTranscoder, Glacier, IoT, IoTData, Lambda
   This means that Bugs and error reports for these APIs will be handled with priority, as they
   would are considered to be functional
 - Fixed documentation issues with S3, CloudFront and Route53 (ilmari)
 - Fixed bug (Issue #108): Services that expected strings as parameters would accept numbers,
   Method(StringParameter => 33), and Paws would generate "StringParameter":33 in the request
   to the service, but the AWS API would error out, forcing the programmer to stringify his input
   Method(StringParameter => "33"). Paws will now auto-stringify the contents in these parameters
   so AWS will accept them correctly, and the programmer doesn't have to worry about stringifying
   his inputs. Thanks to ilmari and rpcme
 - Fixed Bug (Issue #107): Some services transmit undef as a valid value in an Array of things (rpcme)

 - New: perls 5.10 and 5.12 are working after changing package syntax. They've been setup for
        travis testing. This should not be thought of as long term commitment to supporting such
        old perl versions, but at least it can be viewed as we'll know exactly when we stop
        supporting them (and that will be announced in the changelog). Thanks to ilmari for
        a 5.10 support PR)

 - Pass tests on MacOSX by Roger Pettett
 - BREAKING CHANGE: All API methods and attributes have been properly CamelCased. Before
   that, some services were being generated with method names and attributes starting with
   lowercase. For example, in CloudWatchLogs, method DescribeLogGroups would expect:
     limit => Int, logGroupNamePrefix => Str
   Now it expects
     Limit => Int, LogGroupNamePrefix => Str
   The affected services are CloudSearchDomain, CloudTrail, CloudWatchLogs, CodeCommit,
   CodeDeploy, CodePipeline, Support, SimpleWorkflow, Glacier, ECS, DirectConnect, 
   DeviceFarm, DataPipeline, Config. 

   This change also applies to never-released-to-cpan services: MarketplaceCommerceAnalytics,
   IoT, IoTData, Inspector.

 - loaded classes can be made immutable for better performance vs a bit more load time
 - services can be preloaded via Paws->preload (see examples/preload.pl)
 - Experimental Furl caller
 - Proper linking of documentation to appropiate classes
 - All classes now have doc (some innner shapes docs were not being generated) 
 - CloudFront methods had dates appended to them. Now all methods don't have the
   date appended, so anyone using CloudFront should be aware of that API change
 - New iterators for EC2 and Glacier
 - New caller: Paws::Net::FurlCaller. Uses Furl to do HTTP calls

 - S3 API update: Support for ServerSideEncryption 
 - KMS API update: New operations: CancelKeyDeletion ListRetirableGrants ScheduleKeyDeletion and docu update

 - API updates from botocore until 2015-06-29
 - Difference between SQS message AttributeMaps and QueueAttribute maps (thnks codehead) 
 - Paws now returns structured exceptions (Paws::Exception) with information of errors from
   the APIs. The exceptions stringify so you don't have to worry about too much breakage. If you
   were parsing the error message from the exception, you should now use Paws::Exceptions accessors
   to get the already parsed information
 - Refactoring in the different callers to move functionalities only where needed
 - Endpoint resolution support (first version by Iñigo Tejedor)
 - SQS Maps are now working correctly (QueueMaps were ill defined). Thanks to codehead
 - Fix bug for JSONCaller: when response doesn't have a body, the operation would succeed, but an
   invalid json string exception was thrown
 - longs changed to Moose type Int, instead of Num (longs are 64 bit integers 
   in Java https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html)
   Those Ints are passed to AWS as int() instead of Strings, because AWS APIs (CloudWatchLogs
   for example) isn't able to transform String to long (we get an API error)
 - Refactored the config attribute of the Paws class. Also documented what you can configure from
   the config, so now the "config" is official.
 - BugFix: some Map attributes in JSON APIs were incorrectly being created as Maps of Strings, instead of Maps of Objects.
   Affected APIs are: CloudSearchDomain, CloudWatchLogs, CognitoIdentity, Config, DataPipeline, DynamoDB, EMR, Kinesis
   MachineLearning, OpsWorks, S3 and StorageGateway.

 - The default CredentialProviderChain will now try to read an ini
   file in ~/.aws/credentials with the aws credentials
 - The Credential providers have been moved into Paws::Credential namespace
 - The role that all Credential Providers have to add is now Paws::Credential
2015-02-09
 - Paws->service and $aws->service no longer return a class that
   has to be constructed. Instead they return an INSTANCE of the
   class. Attributes for the constructor can be passed as the 
   subsequent parameters of ->service.
   A method class_for_service returns the service class in the "old"
   fashion
   ->service('X')->new(region => 'Y') is now
   ->service('X', region => 'Y')
   or
   ->class_for_service('X')->new(region => 'Y')

   The recommended one is ->service('X', region => 'Y')

 - Adding paginators broke lots of classes (not loading)
   deactivated paginators on json, query and restxml classes
   The only guys who conserves paginators is EC2
