[https://lemmy.ml/post/1465740] > ## What is Lemmy? > > Lemmy is a self-hosted
social link aggregation and discussion platform. It is completely free and open,
and not controlled by any company. This means that there is no advertising,
tracking, or secret algorithms. Content is organized into communities, so it is
easy to subscribe to topics that you are interested in, and ignore others.
Voting is used to bring the most interesting items to the top. > > ## Major
Changes > > ### HTTP API instead of Websocket > > Until now Lemmy-UI used
websocket for all API requests. This has many disadvantages
[https://github.com/LemmyNet/lemmy/issues/2841#issuecomment-1535469357], like
making the code harder to maintain, and causing live updates to the site which
many users dislike. Most importantly, it requires keeping a connection open
between server and client at all times, which causes increased load and makes
scaling difficult. That’s why we decided to rip out websocket entirely, and
switch to HTTP instead. This change was made much more urgent by the sudden
influx of new users. @CannotSleep420 [https://lemmygrad.ml/u/CannotSleep420] and
@dessalines [https://lemmy.ml/u/dessalines] have been working hard for the past
weeks to implement this change in lemmy-ui. > > HTTP on its own is already more
lightweight than websocket. Additionally it also allows for caching of server
responses which can decrease load on the database. Here is an experimental nginx
config [https://github.com/LemmyNet/lemmy-ansible/pull/75] which enables
response caching. Note that Lemmy doesn’t send any cache-control headers yet, so
there is a chance that private data gets cached and served to other users. Test
carefully and use at your own risk. > > ### Two-Factor Authentication > > New
support for two-factor authentication. Use an app like andOTP
[https://f-droid.org/es/packages/org.shadowice.flocke.andotp/] or [Authenticator
Pro]( > https://f-droid.org/packages/me.jmh.authenticatorpro/
[https://f-droid.org/packages/me.jmh.authenticatorpro/]) to store a secret for
your account. This secret needs to be entered every time you login. It ensures
that an attacker can’t access your account with the password alone. > > ###
Custom Emojis > > Instance admins can add different images as emojis which can
be referenced by users when posting. > > ### Other changes > > #### Progressive
Web App > > Lemmy’s web client can now be installed on browsers that support
PWAs, both on desktop and mobile. It will use an instance’s icon and name for
the app if they are set, making it look like a given instance is an app. > >
Note for desktop Firefox users: the desktop version of Firefox does not have
built in support for PWAs. If you would like to use a Lemmy instance as a PWA,
use use this extension
[https://addons.mozilla.org/en-US/firefox/addon/pwas-for-firefox/]. > > ####
Error Pages > > Lemmy’s web client now has error pages that include resources to
use if the problem persists. This should be much less jarring for users than
displaying a white screen with the text “404 error message here”. > > #### Route
Changes > > Pages that took arguments in the route now take query parameters
instead. For example, a link to lemmy.ml [http://lemmy.ml]’s home page with a
few options used to look like this: > > >
https://lemmy.ml/home/data_type/Post/listing_type/All/sort/Active/page/1 > > >
The new route would look like this: > > > https://lemmy.ml?listingType=All > >
Note that you now only have to specify parameters you want instead of all of
them. > > #### Searchable select redesign > The searchable selects, such as
those used on the search page, have a new look and feel. No more inexplicable
green selects when using the lightly themes! > > #### Share button > > Posts on
the web client now have a share button on supported browsers. This can be used
to share posts to other applications quickly and easily. > > #### Lemmy-UI
Overall look and feel > > lemmy-ui is now upgraded to bootstrap 5, and every
component is now much cleaner. > > Special thanks to sleepless
[https://github.com/SleeplessOne1917], alectrocute
[https://github.com/alectrocute], jsit [https://github.com/jsit], and many
others for their great work on improving and re-organizing lemmy-ui. > > ####
Database optimizations > > Special thanks to johanndt
[https://github.com/johanndt], for suggesting improvements to Lemmy’s database
queries. Some of these suggestions have already been implemented, and more are
on the way. > > Query speed is Lemmy’s main performance bottleneck, so we really
appreciate any help database experts can provide. > > #### Captchas > > Captchas
are not available in this version, as they need to be reimplemented in a
different way. They will be back in 0.18.1, so wait with upgrading if you rely
on them. > > ## Upgrade instructions > > Follow the upgrade instructions for
ansible [https://github.com/LemmyNet/lemmy-ansible#upgrading] or docker
[https://join-lemmy.org/docs/en/administration/install_docker.html#updating]. >
> If you need help with the upgrade, you can ask in our support forum
[https://lemmy.ml/c/lemmy_support] or on the Matrix Chat
[https://matrix.to/#/!OwmdVYiZSXrXbtCNLw:matrix.org]. > > ## Support development
> > We (@dessalines and @nutomic) have been working full-time on Lemmy for
almost three years. This is largely thanks to support from NLnet foundation
[https://nlnet.nl/]. > > If you like using Lemmy, and want to make sure that we
will always be available to work full time building it, consider donating to
support its development [https://join-lemmy.org/donate]. No one likes recurring
donations, but they’ve proven to be the only way that open-source software like
Lemmy can stay independent and alive. >
