# 0.12.8

Bokeh Version `0.12.8` is an incremental update that adds a few important features and fixes several bugs. Some of the highlights include:

- JupyterLab integration with the jupyterlab_bokeh extension
- Efficient binary transport for sending arrays to clients
- Improvements to new Graph/Network capability

Many other small bugfixes and docs additions. For full details see the CHANGELOG.

## Migration Guide

NOTE: the 0.12.x series is the last planned release series before a version 1.0 release. For more information see the project roadmap.

### Deprecated `bokeh.charts` support removed

The `bokeh.charts` module, which was simply a compatibility shim to load the separate `bkcharts` package, has been removed. Additionally, Bokeh itself no longer lists `bkcharts` as a dependency. In order to continue using `bkcharts` code, the `bkcharts` package must be installed separately.

### Deprecated MPL compatibility removed

The `bokeh.mpl` module and all supporting code in `bokeh.core.compat` has been removed. Bokeh no longer offers or attempts any automatic MPL conversion.

### Table Date Formatter Changes

A regression in `0.12.7` caused the `DateFormatter` to stop functioning. The problem has been fixed, however instead of the previously accepted JQuery style formats, the``format`` property now only accepts

- standard strftime format strings (making it consistent with `DatetimeTickFormatter`)

- any of the following additional predefined formats names:

  Format name(s) | Format string | Example Output
  --- | --- | ---
  `ATOM` / `W3C` / `RFC-3339` / `ISO-8601` | `"%Y-%m-%d"` | 2014-03-01
  `COOKIE` | `"%a, %d %b %Y"` | Sat, 01 Mar 2014
  `RFC-850` | `"%A, %d-%b-%y"` | Saturday, 01-Mar-14
  `RFC-1123` / `RFC-2822` | `"%a, %e %b %Y"` | Sat, 1 Mar 2014
  `RSS` / `RFC-822` / `RFC-1036` | `"%a, %e %b %y"` | Sat, 1 Mar 14
  `TIMESTAMP` | (ms since epoch) | 1393632000000

  Note that the previously available format name `TICKS` is no longer supported.

### Old Testing Functions Removed

The functions `bokeh.test` and `bokeh.util.testing.runtests` have been removed immediately. Tests should be run as described in the testing section of the Developer’s Guide.

The function `bokeh.util.testing.print_versions` has been removed immediately. The `bokeh info` command (or `python -m bokeh info`) should be used instead.

### Refactor of `bokeh.client` and `bokeh.document`

The `bokeh.client` and `bokeh.document` packages were refactored, to make maintenance and testing simpler, and to improve overall code quality. No commonly used or demonstrated public APIs were affected, (no example code required any changes). The other files that were moved or changed are not expected to impact user code.

### End of Official Support for Python 3.4

Starting with this release, Bokeh is no longer continuously tested against Python 3.4. Use of Bokeh with Python 3.4 will very likely still work, but there are no longer any guarantees backed by CI testing.
