cmlenz@233: Upgrading Genshi
cmlenz@233: ================
cmlenz@233: 
cmlenz@336: Upgrading from Genshi 0.3.x to 0.4.x
cmlenz@336: ------------------------------------
cmlenz@336: 
cmlenz@336: The `genshi.template` module has been refactored into a package with
cmlenz@336: multiple modules. While code using the normal templating APIs should
cmlenz@336: continue to work without problems, you should make sure to remove any
cmlenz@336: leftover traces of the `template.py` file on the installation path.
cmlenz@336: This is not necessary when Genshi was installed as a Python egg.
cmlenz@336: 
cmlenz@344: Results of evaluating template expressions are no longer implicitly
cmlenz@344: called if they are callable. If you have been using that feature, you
cmlenz@344: will need to add the parenthesis to actually call the function.
cmlenz@344: 
cmlenz@347: Instances of `genshi.core.Attrs` are now immutable. Filters
cmlenz@347: manipulating the attributes in a stream may need to be updated. See
cmlenz@347: the docstring of the `Attrs` for more information.

cmlenz@233: Upgrading from Markup
cmlenz@233: ---------------------
cmlenz@233: 
cmlenz@233: Prior to version 0.3, the name of the Genshi project was "Markup". The
cmlenz@233: name change means that you will have to adjust your import statements
cmlenz@233: and the namespace URI of XML templates, among other things:
cmlenz@233: 
cmlenz@233:  * The package name was changed from "markup" to "genshi". Please
cmlenz@233:    adjust any import statements referring to the old package name.
cmlenz@233:  * The namespace URI for directives in Genshi XML templates has changed
cmlenz@233:    from http://markup.edgewall.org/ to http://genshi.edgewall.org/.
cmlenz@233:    Please update the xmlns:py declaration in your template files
cmlenz@233:    accordingly.
cmlenz@233: 
cmlenz@233: Furthermore, due to the inclusion of a text-based template language,
cmlenz@233: the class:
cmlenz@233: 
cmlenz@233:   `markup.template.Template`
cmlenz@233: 
cmlenz@233: has been renamed to:
cmlenz@233: 
cmlenz@233:   `markup.template.MarkupTemplate`
cmlenz@233: 
cmlenz@233: If you've been using the Template class directly, you'll need to
cmlenz@233: update your code (a simple find/replace should do--the API itself
cmlenz@233: did not change).
