Updating Soapbox
You should always check the release notes/changelog in case there are deprecations, special update changes, etc.
Besides that, it's relatively pretty easy to update Soapbox. Just download the new release and unpack the files.
Updating with the command line
To update Soapbox via the command line, do the following:
sh
# Download the build.
curl -O https://dl.soapbox.pub/main/soapbox.zip
# Unzip the new build to where Soapbox was installed before.
# For example, with Pleroma:
busybox unzip soapbox.zip -o -d /opt/pleroma/instance/static
After updating Soapbox
The changes take effect immediately, just refresh your browser tab.
