• Versioning supports pep440 for alpha and beta releases 468daa2
• Don't run slugify test if unidecode package is not installed. Fixes #206

1.2.0

Pulsar 1.2 is broadly backward compatible with the 1.1 version with the only caveat that the is_async function is now deprecated and replaced by the isawaitable function. Warnings will be issued when used by client applications.

In addition, pulsar 1.2.x is the last minor release ("major.minor.micro") to support python 3.4.
From pulsar 1.3.x, support for python 3.4 will be dropped and the new async-await syntax will be used in the whole codebase.

New Features

• Added isawaitable function and deprecated is_async which will be removed
  in version 1.3. Issue #203 6a2f9e4
• Verify parameter in http client. Fixes #191 4611261
• Hindi pulsar, need double check c83e178

Bug fixes and Enhancements

• Versioning supports pep440 for alpha and beta
  releases too 468daa2
• Tidy up cython extensions. No more py2 checks. Better dev version to avoid warning
  in command line 6d369f0
• fix #211
• Fix #209

Examples

• Added Green Flask example applications to illustrate how to use synchronous web frameworks and
  pulsar greenio module 1855819

Test

• Links test c80b163
• Don't run slugify test if unidecode package is not installed. Fixes #206

Wsgi

• Check for missing suffix in the file when serving media files bc6e04d

Fully compatible with async/await

Make sure the asyncio.coroutine decorator is used by all pulsar coroutines
This allows to use pulsar to write python 3.5 compatible code with the
async/await syntax. 709f9ff

Documentation

• Mcve reference in the readme b49434d
• Removed CHANGELOG.rst from the top level directory and created a folder inside
  the docs which contains a list of minor releases

• Http client uses the base class connection method rather than using a
  different one b584828
• The http response object has the links attribute which return a parsed
  Links headers dictionary. Code from python requests 023ca50

Wsgi

• Use file_response function in MediaMixin.serve_file method c012af1
• FileRouter is now a proxy for MediaRouter

WSGI File Wrapper

• Removed release application and created a new repository for it (https://github.com/quantmind/git-agile)
• wait method in greenio app accepts an extra parameter for checking if in child greenlet
• Specialised MustBeInChildGreenlet error for functions which should be called on a child greenlet
• Critical bug fix in pubsub subscribe method for Redis backend
• Added an asynchronous wsgi.file_wrapper to the WSGI environment
• Added file_response utility to serve local files
• Introduced pulsar.ensure_future in place of pulsar.async

HTTP client improvements

• Full support for python 3.5

Core

• Added CI for python 3.5
• Added debug properties to all AsyncObject. The property returns the event loop
  debug mode flag

HttpClient

• Backward incompatible changes with API much closer to requests_ and far better support for streaming both uploads and downloads
• Added content attribute to HttpResponse, in line with requests_
• Ability to pass stream=True during a request, same API as python requests_
• Added the raw property to the Http Response, it can be used in conjunction with
  stream to stream http data. Similar API to requests_

• You can now pass proxies dictionary during a request
• Stream uploads by passing a generator as data parameter
• Better websocket upgrade process
• Tidy up CONNECT request url (for tunneling)
• Added tests for proxyserver example using requests_

WSGI

• Both wsgi and http apps use the same pulsar.utils.httpurl.http_chunks
  function for transfer-encoding chunked
• render_error escapes the Exception message to prevent XSS_

Data Store

• Better pulsards_url function, default value form cfg.data_store
• key_value_save set to empty list by default (no persistence)
