User packages
In addition to the four public packages, Fusion supports user-created packages. User packages appear under User packages in the Library. You can create your own nodes and graphs, import a package from a .package.zip file, and export a package to share it with others or back it up.
To perform actions on the User packages section, click More 
next to User packages in the Library panel. The More menu offers Create package, Import package, and Export package.
To manage an individual package, right-click its name in the Library. The menu offers Export, Publish, Manage dependencies, and Delete.
Package versions
Version numbers use the major.minor.patch format, for example 1.2.3. The major number changes for breaking updates, the minor number for new features, and the patch number for small fixes or incremental saves.
A user package is always in one of two states:
- Draft: Actively editable. The patch number in the version string (for example,
0.1.5) increments each time you save. Draft packages aren't suitable as stable dependencies. - Published: A numbered, stable snapshot. Published versions always end in
.0(for example,0.2.0or1.0.0). Other packages can depend on a published version.
To create a published version, right-click the package and select Publish. Choose Minor bump or Major bump to set the new version number, then click Publish. See Publish a user package.
To revert a published package to draft so you can continue editing, right-click it and select Delete. This doesn't remove the package; it returns it to draft state. To permanently remove a draft package, right-click the draft and select Delete again. See Publish a user package for the full lifecycle.
Package dependencies
When your package uses nodes from other packages, those packages are dependencies. Right-click your package and select Manage dependencies to control which version of each dependency the package accepts. See Manage package dependencies.
