==== UHSDR version scheme ====
Details on the UHSDR version numbering scheme can be found [[https://github.com/df8oe/UHSDR/wiki/Firmware-and-Bootloader-Versioning-Scheme-Explanation|here]].

UHSDR version numbers consists of the parts MAJOR.MINOR.PATCH, e.g.: "2.6.0".

**MAJOR** denotes substantial changes in firmware (e.g. very different interface concept, changed hardware). The major number changes seldomly.

**MINOR** may denote two things: all **even** minor numbers denote release builds. All **odd** minor numbers denote development versions. those change frequently. 

**PATCH** denotes the patch level. For released builds (even minor number) the patch level is normally 0, except when bugs have been corrected in the release version instead of issuing a new release. For development releases (odd MINOR number) the patch level changes frequently.


==== Download UHSDR Software ====
**Official** UHSDR Releases are archived [[https://github.com/df8oe/UHSDR/releases|here]].

These most actual builds are so called "daily builds", created by the development team for their own use. 
  * Advantage: these newest versions contain bug fixes and most recent features. 
  * Disadvantage: "Dailys" may have issues. In this case please temporarilly try older dailys from the archive, or use the official "stable" release (see above).
