 Changelog
 =========
 
+v.0.3.0 - 22 may 2017
+:::::::::::::::::::::
+
+Features
+--------
+
+* ContextProcessors can now be implemented by getting the "yield" value (v = yield x), shortening the teardown-only context processors by one line.
+* File related writers (file, csv, json ...) now returns NOT_MODIFIED, making it easier to chain something after.
+* More consistent console output, nodes are now sorted in a topological order before display.
+* Graph.add_chain(...) now takes _input and _output parameters the same way, accepting indexes, instances or names (subject to change).
+* Graph.add_chain(...) now allows to "name" a chain, using _name keyword argument, to easily reference its output later (subject to change).
+* New settings module (bonobo.settings) read environment for some global configuration stuff (DEBUG and PROFILE, for now).
+* New Method subclass of Option allows to use Configurable objects as decorator (see bonobo.nodes.filter.Filter for a simple example).
+* New Filter transformation in standard library.
+
+Internal features
+-----------------
+
+* Better ContextProcessor implementation, avoiding to use a decorator on the parent class. Now works with Configurable instances like Option, Service and Method.
+* ContextCurrifier replaces the logic that was in NodeExecutionContext, that setup and teardown the context stack. Maybe the name is not ideal.
+* All builtin transformations are of course updated to use the improved API, and should be 100% backward compatible.
+* The "core" package has been dismantled, and its rare remaining members are now in "structs" and "util" packages.
+* Standard transformation library has been moved under the bonobo.nodes package. It does not change anything if you used bonobo.* (which you should).
+* ValueHolder is now more restrictive, not allowing to use .value anymore.
+
+Miscellaneous
+-------------
+
+* Code cleanup, dead code removal, more tests, etc.
+* More documentation.
+
+v.0.2.4 - 2 may 2017
+::::::::::::::::::::
+
+* Cosmetic release for PyPI package page formating. Same content as v.0.2.3.
+
+v.0.2.3 - 1 may 2017
+:::::::::::::::::::::
+
+* Positional options now supported, backward compatible. All FileHandler subclasses supports their path argument as positional.
+* Better transformation lifecycle management (still work needed here).
+* Windows continuous integration now works.
+* Refactoring the "API" a lot to have a much cleaner first glance at it.
+* More documentation, tutorials, and tuning project artifacts.

 * Input/output MUX DEMUX removed, maybe no need for that in the real world. May come back, but not in 1.0
 * Change dependency policy. We need to include only the very basic requirements (and very required). Everything related
   to transforms that we may not use (bs, sqla, ...) should be optional dependencies.
