* StackStorm Web UI (``st2web``) has been updated to not render and display execution results
larger than 200 KB directly in the history panel in the right side bar by default anymore.
Instead a link to view or download the raw result is displayed.

Execution result widget was never optimized to display very large results (especially for
executions which return large nested dictionaries) so it would freeze and hang the whole
browser tab / window when trying to render / display large results.

If for some reason you want to revert to the old behavior (this is almost never a good idea
since it will cause browser to freeze when trying to display large results), you can do that by
setting ``max_execution_result_size_for_render`` option in the config to a very large value (e.g.
``max_execution_result_size_for_render: 16 * 1024 * 1024``).
