To update Flarum, you'll need to use Composer. If you're not familiar with it (although you should be, because you need it to install Flarum), read our guide for information on what it is and how to set it up.
If updating across major versions (e.g. <=0.1.0 to 1.x.x, 1.x.x to 2.x.x, ...), make sure to read the appropriate "major version update guide" before running the general upgrade steps.
Step 1: Make sure all your extensions have versions compatible with the Flarum version you're trying to install. This is only needed across major versions (e.g. you probably don't need to check this if upgrading from v1.0.0 to v1.1.0, assuming your extensions follow recommended versioning). You can check this by looking at the extension's Discuss thread, searching for it on Packagist, or checking databases like Extiverse. You'll need to remove (not just disable) any incompatible extensions before updating. Please be patient with extension developers!
Step 2: Take a look at your
composer.json file. Unless you have a reason to require specific versions of extensions or libraries, you should set the version string of everything except
flarum/mentions, and other bundled extensions). Make sure
flarum/core is NOT set to
*. If you're targeting a specific version of Flarum, set
flarum/core to that (e.g.
"flarum/core": "v0.1.0-beta.16). If you just want the most recent version, use
Step 3: If your local install uses local extenders, make sure they are up to date with changes in Flarum.
Step 4: We recommend disabling third-party extensions in the admin dashboard before updating. This isn't strictly required, but will make debugging easier if you run into issues.
Step 5: Make sure your PHP version is supported by the version of Flarum you are trying to upgrade to, and that you are using Composer 2 (
Step 6: Finally, to update, run:
composer update --prefer-dist --no-plugins --no-dev -a --with-all-dependencies
php flarum migrate
php flarum cache:clear
Step 7: If applicable, restart your PHP process and opcache.

Errors While Updating
Here we'll go through several common types of issues while trying to update Flarum.
If the output is short and contains:
Nothing to modify in lock file
Or does not list
flarum/core as an updated package, and you are not on the latest flarum version:
- Revisit step 2 above, make sure that all third party extensions have an asterisk for their version string.
- Make sure your
flarum/coreversion requirement isn't locked to a specific minor version (e.g.
^1.0.0isn't). If you're trying to update across major versions of Flarum, follow the related major version update guide above.
For other errors, try running
composer why-not flarum/core VERSION_YOU_WANT_TO_UPGRADE_TO
If the output looks something like this:

... (this'll go on for a bit)
It is very likely that some of your extensions have not yet been updated.
- Revisit step 1 again, make sure all your extensions have versions compatible with the core version you want to upgrade to. Remove any that don't.
- Make sure you're running
composer updatewith all the flags specified in the update step.
If none of this fixes your issue, feel free to reach out on our Support forum. Make sure to include the output of
php flarum info and
composer why-not flarum/core VERSION_YOU_WANT_TO_UPGRADE_TO.
