# Recent feature changes to Stack Exchange

This is an unofficial list/changelog of new features and various changes to Stack Overflow and the Stack Exchange network.

It is maintained by the community, while a Stack Exchange employee changes the accepted answer to ensure that the latest changes remain on top (given default user settings).

To see the list in reverse chronological order (latest entry on top), sort Answers by latest activity first.

For those adding new features here: please post only feature changes that affect the whole network and have some global impact. i.e. bug fixes don't belong here, nor do mobile app updates.

• "sort Answers by latest activity first" doesn't work because people are updating the grammar of past archives bumping them up. Is there a way to sort by post creation date for this thread? – Pacerier Jan 20 '16 at 7:35
• @Pacerier: Yes, hit "Oldest" and scroll down the list. (Accepted answer will always be on top of course.) – Nathan Tuggy Apr 14 '16 at 0:37
• why does this have 9 answers and not just one? – user1306322 May 30 '17 at 15:58
• So what are the new SQL features in Data Explorer we were promised in May? – Scott Jun 9 '17 at 21:26
• @user1306322 because in the beginning, there were too many new features, so it passed the 30k character limit. So it was decided to split it per year. Even though in recent years there are way less changes, this tradition is kept. – Shadow Wizard Jul 22 '17 at 8:41
• @Scott good question, but even if we knew, not sure it belongs here as SEDE is "external service". Feel free to start a new support or discussion question asking about those new features. :) – Shadow Wizard Jul 22 '17 at 8:42

### January 2019

• Re Census -- after? I don't recall seeing an option to choose a site, only whether to claim the badge. Doesn't it depend on which site you entered from? – Monica Cellio Jan 25 at 21:58
• @MonicaCellio After filling in the survey, you see two buttons: a big blue button to get the badge on Stack Overflow, and a smaller button right beside it to choose a site. If you click on the latter button, you are given a list of sites to choose from. – Sonic the Introverted Hedgehog Jan 28 at 9:45
• Does someone have a source post for the feature change of comment deletion now being done by clicking a "Delete" link rather than an "X" icon? The change was made in the last 12-18 hours for sure. – TylerH Jan 31 at 22:44
• @TylerH Added it in. – Sonic the Introverted Hedgehog Feb 1 at 2:27

### December 2011

• 2011-12-28: There's a tag-wiki-specific "not helpful... does not follow any of our tag wiki guidelines" suggested-edit rejection reason.

### October 2013

• 2013-10-08: Deleted answers that have had any spam or offensive flags raised against them will not show the answer body but the following text: "This answer was marked as spam or offensive and is therefore not shown - you can see the revision history for details".

• 2013-02-06: The auto inserted text for questions closed as duplicates has been changed to "This question already has an answer here:" followed by link to the other question and the number of answers it has. The text is no longer edited into the original question but rather displayed externally.

• 2012-09-21: New badges added for completing community review tasks. User can earn Custodian (1 review), Reviewer (250 reviews) and Steward (1000 reviews) once for each review queue (Close Posts, First Posts, Late Answers, Suggested Edits and Low Quality Posts).

• 2016-09-29 is in the revisions history (Rev 5), when feature request was retagged to status-completed – gnat Feb 28 '17 at 8:48

• 2011-02-09: Migration now does tag checks. During migration, tags will be checked (and replaced if found) for tag synonyms on the destination site. Tags that do not exist on the destination site will be stripped from the question. If the previous steps leave a question with no remaining tags, it will be closed as off-topic on the original site and not migrated, unless it had only one tag that also is a "global tag" on the destination site (e.g. questions can be migrated to TeX.se and will be ).

• 2011-02-09: Flagging for moderator attention now counts for the Citizen Patrol badge. This change applies retroactively.

• 2011-02-09: Privilege changes: Create tags has been raised from 150 to 300. Retag has been raised from 200 to 500. A new 5k privilege to approve or reject tag wiki edits has been added.

• 2011-01-13: Flag dialog improved. Its "flag for moderator attention" option now provides several default reasons, where appropriate: "not an answer", "low quality" and "should be CW". It allows for longer messages to a moderator. The daily maximum number of flags has been increased. And if a particular user keeps moderator flagging for reasons that are considered invalid, their flag weight decreases. And for those users who continually flag reliably, their flag weight increases.

• 2011-01-07: Moderators can now convert answers into comments.

### Unknown during 2017

• @gnat regarding the protocol edit, it is not needed anymore now that MSE is fully HTTPS. Non HTTPS link will just redirect to HTTPS so it doesn't matter. – Shadow Wizard Apr 4 '17 at 5:55

### April 2018

• 2018-04-27: The feature to allow <5 rep users to ask on the per-site meta about their own post was enabled on Stack Overflow.

### January 2018

• @user13107 it's a joke, right? Just do something and the account won't be deleted. What is the point of keeping an inactive account??? – Shadow Wizard Jun 2 '18 at 12:49
• @ShadowWizard what if people take a 2 year hiatus and return to SO. It can certainly happen. – user13107 Jun 5 '18 at 2:00
• @user13107 so they create a new account. Nothing to keep in their old account anyway. – Shadow Wizard Jun 5 '18 at 4:10
• @ShadowWizard Nothing to keep in their old account anyway Is that so, then I think I misunderstood. I wrongly thought that autodeletion will take place if there is no activity for 2 years (even if there is a lot of activity prior to those two years). It seems to me that the correct way to interprete this feature is - if there is no activity in your account (from the start) then it will be auto deleted. – user13107 Jun 5 '18 at 4:38
• @user13107 big misunderstanding indeed. Read this answer for the full details. – Shadow Wizard Jun 5 '18 at 6:24
• @Sonic the list here is for new features, not for bug fixes. Feel free to start a new "Recent bug fixes in Stack Exchange", but here such things do not fit. – Shadow Wizard Sep 8 '18 at 8:33
• @Shadow Please read this post's last bullet. The bug report was previously declined, so there is a feature request asking for it to be changed. – Sonic the Introverted Hedgehog Sep 8 '18 at 17:10
• @SonictheInclusiveWerehog: The change in the tag warnings also exists on sites that are still running the old design, e.g., try [critique] on Graphic Design. I therefore assume that it is an independent thing. – Wrzlprmft Sep 26 '18 at 16:57
• @Wrzlprmft That's still the incorrect formatting for "unknown" dates; see the 2017 answer for the proper formatting. – Sonic the Introverted Hedgehog Sep 26 '18 at 16:59
• @Sonic: I don’t see why it is mandatory to translate the formatting of those events to this case – which is different by nature. In those cases, some way of doing things trickled out, which is naturally fuzzy; here, there is a specific date, which is just unknown. I am pretty confident that the change happened in September (and if somebody knows better or more precise, they can edit to narrow it down – which is most likely going to happen anyway), thus putting it in the actual month is more useful for readers, since it is easier to locate, etc. – Wrzlprmft Sep 26 '18 at 18:19
• @gnat with all due respect don't you think drawing attention to Sonic and IPS is overkill? Shouldn't this post be concerned with the software that affects every website? Why not wait a week or two and see if IPS is reintroduced in the HNQ? – Mari-Lou A Oct 19 '18 at 10:36
• @Mari-LouA this list is heavily used to answer questions about how system works and placing change descriptions here serves exactly this purpose, it has nothing to do with bringing attention – gnat Oct 19 '18 at 11:43
• @gnat is its exclusion felt net-wide? Does it affect all users? IPS users can refer to their meta if they want answers. The OP says …new features and various changes to Stack Overflow and the Stack Exchange network.…* Not various changes to IPS – Mari-Lou A Oct 19 '18 at 12:05
• @Mari-LouA yes it did, IPS was among top five sites at HNQ both by clicks and distribution so this change is definitely noticeable network wide (while we're at it, whole HNQ feature is meant to be network wide) – gnat Oct 19 '18 at 12:07
• @Mari-LouA FYI the second answer on that post gnat linked says that it won't be restored until next year at a minimum. – Sonic the Introverted Hedgehog Oct 19 '18 at 17:38

### Nov 2010

• 2010-11-24: Mouseover of chat messages now highlights any replies to that message.

• 2010-11-13: The "activity" tab of the user profile now gives the option to dynamically show the content of recently posted answers.

• 2010-11-09: Questions are now sorted by "amount of interest" on the homepage rather than time of last activity. (Stack Overflow only.)

• 2010-11-08: The frequency of the notification envelope lighting up has been toned down in favor of the global inbox.

• 2010-11-07: Behavior of [tag:tags] on meta sites updated to refer to the parent site by default; new syntax introduced for a meta-site's own tags (source).

• 2010-11-07: Support for the <kbd> tag re-enabled on Meta Stack Overflow.

• 2010-11-05: Posting links to the very same site now automatically shows the title. So, just insert https://meta.stackexchange.com/questions/59445/whatever. to become Recent feature changes to Stack Exchange. The title is not shown in the preview, but inserted when the post is created or edited. The title is not updated when it changes, unless the post is edited. It does not work in comments, nor for links to other SOFU sites. Trailing punctuation marks such as a comma, dot or question mark (without URL parameters) to get a readable sentence work just fine.

• 2010-11-05: Posting tags inside questions and answers now works. Example: instead of writing [[tags]](https://meta.stackexchange.com/questions/tagged/tags) to display [tags], users can now write [tag:tags] to display .

• 2010-08-17: hot questions formula has been tweaked: Succeeding questions from the same site are penalized by increasing amounts. Community wiki questions are penalized. The benefit of many answers is capped at 10, and we only look at the score of the top 3 answers. We only degrade based on question age, and not the last update date on a question.

• 2010-08-13: An image-upload capability has been added, accessible through the image option in the toolbar.

• 2010-08-10: Questions from IP addresses or accounts with a history of extremely poor questions are no longer being accepted. Votes on questions are taken into account, and this yields a permanent IP ban, showing "Sorry, we are no longer accepting questions from this account".

• 2010-08-06: (and other meta-tags) are now banned.

• 2010-08-03: Searching within favorites is now included in advanced search.

### Apr 2010

• 2010-04-30: The vote-undo locked text was changed into a more specific "You last voted on this question / Mar 28 at 7:55 / Your vote is now locked in / unless this question is edited", hence also allowing you to see when you voted if your memory fails you.

• 2010-04-25: A new "Linked" posts column on the right, above the existing "Related" posts. It's limited to 50 links, and ordered to put the "best" related links at the top (score, # answers, # views, answer scores).

• 2010-04-01: Inline links in comments, [the Markdown way](http://example.com)`.

### Oct/Nov/Dec 2009

• 2009-12-27: Edit your own comments, within a 5 minute window, yielding the little pencil icon: .

• 2009-11-30: Show up/down vote totals when clicking the vote count: Need a minimum number of reputation points to see this (currently 1,000, though it could vary from site to site).

• 2009-10-02: Cut off internal links in comments show the question title (actually: the text after the question number in the URL, without the dashes) in the hover text.

Thank you for your interest in this question. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).

Would you like to answer one of these unanswered questions instead?
