 ## CHANGELOG
 
+### `@krassowski/jupyterlab-lsp 3.4.0` (unreleased)
+
+- features:
+
+  - the priority of the completions from kernel can now be changed by switching new `kernelCompletionsFirst` setting ([#520])
+  - completer panel will now always render markdown documentation if available ([#520])
+    - the implementation re-renders the panel as it is the best we can do until [jupyterlab#9663](https://github.com/jupyterlab/jupyterlab/pull/9663) is merged
+  - the completer now uses `filterText` and `sortText` if available to better filter and sort completions ([#520])
+
+- bug fixes:
+  - completer documentation will now consistently show up after filtering the completion items ([#520])
+  - completions containing HTML-like syntax will be displayed properly (an upstream issue) ([#520])
+
