Release management
Learn about versioning of the Pdftools products and their supported releases.
Versioning
The Pdftools products use semantic versioning. The version is marked as MAJOR.MINOR.PATCH. For example, a product with version 5.1.1 indicates a major version 5, a minor version 1, and a patch version 1.
Release types of the Pdftools products
There are two release types in the Pdftools products:
- Feature release: Receives regular updates with new functionalities and bug fixes. As a result, feature releases get stability improvements, new features, and product advancements.
- Long-term support (LTS) release: Receives regular patches with bug fixes for two years. The LTS release involves extended test and integration processes. As a result, this type of release focuses mostly on long-term stability.
See the following table for an overview of the Pdftools product releases:
| Release type | Frequency | Content | Patch support |
|---|---|---|---|
| Feature release | Monthly |
| Provided until the next feature release. |
| LTS | Yearly |
| Provided for two years. |
