Update steps

The following instructions are for updating from 4.7.3.

If you are upgrading directly from an earlier release, please carefully read the upgrade notes for the skipped releases as well, as they often require extra steps such as database migrations. In particular, it is very important to read the 4.7.0 release notes.

Non-Docker

[!TIP]
The charlock_holmes gem may fail to build on some systems with recent versions of gcc.
If you run into this issue, try BUNDLE_BUILD__CHARLOCK_HOLMES="--with-cxxflags=-std=c++17" bundle install.

1. If you are using rbenv, update the list of available versions and install the proper Ruby version by doing RUBY_CONFIGURE_OPTS=--with-jemalloc rbenv install in the Mastodon install directory (e.g. /home/mastodon/live)
2. Install dependencies with bundle install and yarn install --immutable
3. Precompile the assets: RAILS_ENV=production bundle exec rails assets:precompile
4. Restart all Mastodon processes.

When using Docker

1. Restart all Mastodon processes.
