Topics (with replies) bumped on title edit

Moin · September 22, 2025, 6:19pm

I noticed on my forum and also on Meta that topics are bumped when the title is edited. For me this is quite confusing because the topic appears at the top of the topic list, so I expect something new, but it’s very difficult to spot the change because usually I am taken to the latest post while the edit happened on the first post.

I noticed you changed that edits on the last post no longer bump the topic. Is it possible that the fact that edits of the topic title now trigger a bump is a side effect of that change?

We currently bump the entire topic if the last post in the topic is edited. …This is quite noisy and distracting, particularly in cases where the edit was to address a small typo rather than dramatically rework the post. So, this commit no longer bumps a topic on post edit for any posts in the topic. Only manually bumping the topic in the footer or in bulk actions will bump it now, or when tags/category are edited depending on settings.

It also affects category and tag edits

Thanks. Sounds likely, given that PR was merged a few hours ago. @martin will have a look.

Thanks Moin, I see now…since I’m no longer checking if it’s the last post, I need to check if only topic OP stuff is changing and bypass the bump if so.

I have a fix here:

I was able to reproduce with category changes but not tag changes.

Thank you for fixing this

I bumped Profile picture next to pinned topics by adding a tag in case you need a repro

Okay I can reproduce now, strange, not sure why I couldn’t yesterday.

Hmm okay I think it’s valid for the title not to bump the topic, but I think the category + tag edit based bumps are complicated by these two settings:

github.com/discourse/discourse

config/locales/server.en.yml

51373ecaa


      
          disable_category_edit_notifications: "Disable notifications for topic category edits. This includes topics which are 'published' (e.g. shared drafts)."
          
          disable_tags_edit_notifications: "Disable notifications for topic tag edits. This includes topics which are 'published' (e.g. shared drafts)."

These control whether a topic is bumped when editing the OP:

github.com/discourse/discourse

app/controllers/topics_controller.rb

51373ecaa


      
          def should_bypass_bump?(changes)
            (changes[:category_id].present? && SiteSetting.disable_category_edit_notifications) ||
              (changes[:tags].present? && SiteSetting.disable_tags_edit_notifications)
          end

But, these settings also control whether an actual notification is sent when changing category/tags so it’s a bit complex to detangle. Will discuss this internally a bit and loop back.

Before you removed the bump on edits, title, category, and tag changes only bumped the topic when it had no replies. Otherwise, no bump happened because it wasn’t the last post. Do you plan to restore that, or do you want to block these bumps too?

I also wondered why a category edit on my test topic didn’t bump the topic now. I have the impression it’s because of the editing grace period. After waiting for 5 minutes, editing the category bumped the topic again.

I am still confused about what causes a bump now, apart from a reply. Understanding that could help me find solutions for how I notice edits where the user followed the Discourse instructions to edit their post instead of posting consecutive replies^[1]. I think it might be a frustrating experience when the system tells you to edit your post instead of replying, you do that, and no one notices. I also asked for help on how edits on wikis can be tracked now.

Happy birthday

Will be doing a further tweak here to make it so the title, tags, and category change will not cause the bump. Sit tight…

This fix is done now, so now the title/tag/category edits will not cause bumping:

Followup 2a65bf452224ece92981a9a26579ece67f10855b With the above change, we i…nadvertently made it so that when you edited the topic title or category, we bumped the topic. This fix makes it so we do not bump topics when only title, category, or tags are changed, to restore the previous behaviour. In addition, we are making it so the following settings no longer influence topic bump behaviour, keeping only their intended notification behaviour around. The site setting description never mentioned anything about topic bumps: * disable_category_edit_notifications * disable_tag_edit_notifications
