Prerelease Software Downloads
Prerelease software enable us to provide early and frequent builds of our products under development. It enables us to collect your valuable, real-world feedback throughout the product development cycle, so that we can ship higher quality products. Sharing prerelease software with you help us innovate and deliver the products we know that you will continue to value and appreciate.
- Release Candidate (RC) software is a version of the product (usually the most recent) that is deemed complete and stable enough to become the released version, but is being made available for customer evaluation of shipping readiness.
- Beta software is an early build release that is not quite ready for use in production environments, but is of sufficient quality to enable evaluation for feedback about the software.
- Previews enable us to provide more frequent releases to solicit early feedback that will help shape the software in its earliest stages.
