The Episerver framework is simply a set of NuGet packages that are part of a web application, which can be hosted locally or in the cloud. Episerver is easily upgraded through Visual Studio and the NuGet package manager. New releases are available weekly, making it easy to keep your solutions up to date.

Episerver products consist of a main NuGet package with dependencies to other required packages. When updating, you only have to select the main package.
Episerver release packages are published to the Episerver NuGet feed. You can download and install release packages from here via the Package Manager or command prompt in Visual Studio.
Episerver follows semantic versioning. Release packages are numbered with a three-digit series, for example 10.2.0.
When the first digit is bumped, the release is called a major version. Major versions are releases that have some breaking changes. And by breaking changes, we mean that a developer may have to change something in their code before they can upgrade.
When the second digit is bumped, the release is called a minor version. A minor release has some new features. When the third digit is bumped, the release is a bugfix version and only contains bug fixes. It does not contain any new functionality.
Example of releases:
10.0.0 (breaking changes) -> 10.1.0 (contains same functionality as 10.0.0 plus some new functionality) -> 10.1.1 (contains same functionality as 10.1.0 plus some bug fixes) -> 10.2.0 (same functionality as 10.1.1 plus new functionality) -> ... -> 10.8.2 (contains all features and bug fixes from previous versions plus new bug fixes) -> 11.0.0 (breaking changes).
Instead of doing large releases once or twice a year, Episerver uses a continuous release process with short development and test cycles, and release of new versions every week or fortnight.
This way each release only contains a limited number of features and bug fixes, speeding up the time to market and making upgrading smoother. Each new release package is cumulative, which means that it contains all previous updates as well.
As a developer, you decide how often you want to upgrade, but the more often you upgrade, the smoother it is.
To quickly get access to new features that are being developed, you can install Beta features, see Beta features for more information on how to work with these.
