Grabba Driver for Windows
Unified driver for Grabba devices on the Windows operating system
Versioning and Release History

There are no stable unified driver release series at the time of this release (2.0.0-alpha-11). However, stable releases of pre-unification drivers are available on Android (1.x series) and iOS (1.0 series).

The current experimental release series at the time of this release is 2.0, which is presently at alpha quality.

Version Numbers

This driver follows the Grabba unified driver numbering convention, which uses three types of releases:

  • Alpha release (e.g. 2.0.0-alpha-2): may not be feature-complete, and may be subject to further API changes. Bugs are to be expected.
  • Beta release (e.g. 2.0.0-beta-1): contains final feature set and APIs for the release series, but development, review and testing are still ongoing. Bugs are to be expected.
  • Stable release (e.g. 2.0.1-stable): full release; review and testing are complete, no known issues of significance at the time of release, no further development other than bug fixes.

Releases are planned to occur as a number of series, each moving from alpha to beta to full release. Series are specified in terms of a major and minor number, e.g. series 2.0 has major number two and minor number 0. Any changes which introduce incompatibilities to existing APIs will be released under a new major number (e.g. 2.1 -> 3.0); changes under a new minor number (e.g. 2.0 -> 2.1) should not break compatibility.

Note that the version numbers for the Visual Studio extension (VSIX) and any Windows applications released in the Windows Store are slightly different, due to restrictions placed on them by Microsoft. The numbering convention used for the VSIX and any applications which depend on it (e.g. Grabba Demo for Windows) is as follows:

  • VSIX A.B.C11.0 through A.B.C39.0 - alpha release 1 through 29 for version A.B.C
    • Example: driver v2.0.0-alpha-11 is encoded as VSIX v2.0.021.0
  • VSIX A.B.C41.0 through A.B.C69.0 - beta release 1 through 29 for version A.B.C
    • Example: driver v2.0.0-beta-2 is encoded as VSIX v2.0.042.0
  • VSIX A.B.C90.0 - stable release of version A.B.C
    • Example: driver v2.0.2-stable is encoded as VSIX v2.0.290.0
