Update The upgrade was done, DB migrations took around 5 minutes. We'll keep an eye out for (new) issues but for now it seems to be OK.

Original message We will upgrade lemmy.world to 0.18.3 today at 20:00 UTC+2 (Check what this isn in your timezone). Expect the site to be down for a few minutes. ""Edit"" I was warned it could be more than a few minutes. The database update might even take 30 minutes or longer.

Release notes for 0.18.3 can be found here: https://github.com/LemmyNet/lemmy/blob/main/RELEASES.md

(This is unrelated to the downtimes we experienced lately, those are caused by attacks that we're still looking into mitigating. Sorry for those)

Sorry for those

It's not your fault :) We know you admins are working really hard to keep the server as stable as possible.

    • Add controversial ranking
    • Change logic for determining comment default language
    • Add infinite scroll user option

    Neat. I hope the comment language logic change means the default won't be "Undetermined" anymore.

    I'm sure the attacks are just as annoying for you guys as they are to us, if not more. Appreciate the update.

    Edit: Loving the endless scroll for the front page! I've been eagerly awaiting that. Such a small change, but such a big impact.

    Fwiw, it can be helpful to call out the date for such changes. Preferably in YYYY-MM-DD (ISO 8601).

    While it's helpful to link to an off-site timezone converter tool (thanks for that, btw), "today" can be a different date, depending on where in the world you are. For example, Japan, Australia, and New Zealand.

    Great! Thanks for keeping things up to date and running!

  • Really liking the transparency with the community over how the server is doing.

    Great work.

    This version brings major optimizations to the database queries, which significantly reduces CPU usage. There is also a change to the way federation activities are stored, which reduces database size by around 80%.

    Is it me or is the 80% figure just insane? Are there any benchmarks to see how fast this has become versus say Lemmy 0.18.2 on a very large instance?

    Is it me or is the 80% figure just insane?

    Not really, you'd be surprised how often systems are bloated all because of a single option, character, etc. Most developers don't start optimizing until much later in the software's lifecycle. Often enough, it is easily overlooked. That's why code reviews are needed often with fresh pair of eyes.

    Just to set the expectations, reducing database size or CPU usage does not necessarily mean it is faster but it does mean there's more free capacity on the servers to handle more users at the same performance.

    More importantly; they may help reduce costs on the smaller indie instances that doesn't need to buy larger server instances.

    Hopefully, we'll continue to see more of these optimizations.

    Funnily enough, this is the feature that can speed up the performance by doing less calls:

    The federation code now includes a check for dead instances which is used when sending activities. This helps to reduce the amount of outgoing POST requests, and also reduce server load.

    Looks like the upgrade is done and was a quick and easy success, thank you Devs!

    How do you turn on endless scrolling? I'm still seeing page numbers

    Infinite scroll and word filtering. If I see one more post about "AI", Musk, Twitter, or fake superconductors, I might have to get off the computer for 10 whole minutes.

    Why are these announcements the only place I am finding out the Lemmy has an update? I figured there would be more top level discussions about it on Lemmy. Maybe I am just not following the correct communities.

    Thanks as usual for the transparency, y’all.

    Awesome! It’s great to see thing become snappier and better since I joined Lemmy.

    Reddit would almost never update unless it was a pants on fire situation or they would force feed features that no one wanted or even was tested properly.

    A big thank you to everyone involved, FROM those taking the time to submit bug descriptions in a reproducible manner and those making feature requests or those simply upvoting and pointing out the most needed patch/updates TO simultaneously amateur, newly minted coders and veteran developpers pushing small and big patches to fix anything from typos, reformatting old code, cleaning almost unnoticeable UI object, transition less performing backend modules or secure/harden of all these moving parts.

    I am glad to witness and be a part of the perpetual progress of the fediverse.

    Maybe I’m missing it, but I don’t see the option for infinite scroll anywhere. How do I add that?
