 - [#1514](https://github.com/plotly/dash/pull/1514) Perform json encoding using the active plotly JSON engine.  This will default to the faster orjson encoder if the `orjson` package is installed.
 
 ### Changed
-- [#1707](https://github.com/plotly/dash/pull/1707) Change the default value of the `compress` argument to the `dash.Dash` constructor to `False`. This change reduces CPU usage, and was made in recognition of the fact that many deployment platforms (e.g. Dash Enterprise) already apply their own compression. If deploying to an environment that does not already provide compression, the Dash 1 behavior may be restored by adding `compress=True` to the `dash.Dash` constructor. 
+- [#1679](https://github.com/plotly/dash/pull/1679) Restructure `dash`, `dash-core-components`, `dash-html-components`, and `dash-table` into a singular monorepo and move component packages into `dash`. This change makes the component modules available for import within the `dash` namespace, and simplifies the import pattern for a Dash app. From a development standpoint, all future changes to component modules will be made within the `components` directory, and relevant packages updated with the `dash-update-components` CLI command.

 When a change in renderer code doesn't reflect in your browser as expected, this could be: confused bundle generation, caching issue in a browser, Python package not in `editable` mode, etc. The new tool reduces the risk of bundle assets by adding the digest to help compare asset changes.
 
+### Development of `dash-core-components`, `dash-html-components`, and `dash_table`
+
+Specific details on making updates and contributions to `dcc`, `html`, and `dash_table` can be found within their respective sub-directories in the `components` directory. Once changes have been made in the specific directories, the `dash-update-components` command line tool can be used to update the build artifacts and dependencies of the respective packages within Dash. For example, if a change has been made to `dash-core-components`, use `dash-update-components "dash-core-components"` to move the build artifacts to Dash. By default, this is set to update `all` packages.
