WP Discourse version 1.4.5 is now in the WordPress repo. It has a few small changes:
When posts are updated on WordPress, they are no longer automatically republished to Discourse. To republish the post, select the Update Discourse topic checkbox in the Publish to Discourse meta-box.
An option to open the Start Discussion and Continue Discussion links in a new tab has been added. You can find it on the plugin’s Commenting settings tab.
A wpds_sync_discourse_comments action has been added. Calling
do_action( 'wpdc_sync_discourse_comments', $post_id )
will call the WP Discourse sync_comments function for $post_id. It was added to make it possible to use the plugin with the Timber theme, but could have other uses. See WP Discourse Plugin Tips and Tricks for details.
Let me know if there are any problems associated with these changes. You can find older versions of the plugin here: WP Discourse – WordPress plugin | WordPress.org
