Known Issues¶

Server output in the Jupyter notebook with output_server is currently not functioning correctly, and will be fixed in a follow on 0.11.1 release shortly. However, new notebook comms can enable many of the same kinds of interactions and notebook-based apps without a Bokeh server.

The Image glyph does not currently work with the Bokeh server, and will be fixed in a follow on 0.11.1 release shortly.

Migration Guide¶

The previous Flask-based bokeh-server has been completely removed and replaced with the new bokeh serve based on Tornado and a websocket protocol. If you require to use bokeh-server you will have to remain on Bokeh version 0.10.0 or lower.

All “old-style” charts in bokeh._legacy_charts have been updated to use the more consistent and powerful bokeh.charts interface, and bokeh._legacy_charts has been removed.

Bokeh deprecation warnings, which are not enabled by default python, have now been unconditionally enabled and are always displayed.

ColumnDataSource.push_notebook() has been deprecated (but still works) in favor of the more general bokeh.io.push_notebook() base on Jupyter notebook websocket comms.

The following modules have been deprecated (but still work), with new counterparts as described in this table:

Old location	New location
`bokeh.browserlib`	`bokeh.util.browser`
`bokeh.properties`	`bokeh.core.properties`
`bokeh.mixins`	`bokeh.core.property_mixins`
`bokeh.plotting_helpers`	`bokeh.plotting.helpers`
`bokeh.templates`	`bokeh.core.templates`

Additionally, the following modules that should not be of interest to general users have been moved immediately, without deprecation:

Old location	New location
`bokeh._json_encoder`	`bokeh.core.json_encoder`
`bokeh.compat`	`bokeh.core.compat`
`bokeh.enums`	`bokeh.core.enums`
`bokeh.query`	`bokeh.core.query`
`bokeh.state`	`bokeh.core.state`
`bokeh.validation`	`bokeh.core.validation`

If you have been using file_html and manually passing in js_resources or css_resources, your call will no longer work. You can still do this, but you pass a tuple to the resources argument.

Before:

html = file_html(layout, None, title=title, template=template, js_resources=js_resources, css_resources=css_resources)

v0.11:

html = file_html(layout, resources=(js_resources, css_resources), title=title, template=template)

Note you can pass None in place of either js_resources or css_resources.
