XS Roadmap
Contents
Versioning Scheme
Releases will follow a <major>.<feature>.<minor> versioning scheme, as follows:
- 2.0 is our long-term "Next Gen" release somewhere in the distance
- 1.0 is our mid-term "we are proud of it - features and stability" release
- 0.3 will be the first release managed by Martin Langhoff, to sync with Peru's April 2008 deployment
- 0.2 is Build 160 by Wad.
If for example 0.2 needs bugfixes, we'll see a 0.2.1 release. The 0.9 to 1.0 transition will be about stability and polish.
Exactly what happens between 0.2 and 1.0 will be defined via release goals and blueprints (similar to Ubuntu's approach) which will be managed in dev.laptop.org .
Release schedule
The XS should see a new feature release every 3~4 weeks until we hit v1.0. At that point we will encourage installations to switch to v1.0 and ensure the upgrades from earlier releases to 1.0 work smoothly. From 1.0 onwards the release cycle will be slower - probably about 4 months.
Upgradeability considerations
A key consideration is that once XS is widely installed, countries/regions will want to limit the number of upgrades they apply to the XS. During the 1.x cycle, we must support environments where the XS has a yearly upgrade. That means that with a 4-month cycle 1.0 must be able to upgrade to 1.4 smoothly.
Deployment managers need to be aware that XSs must be upgraded frequently until 1.0, and yearly during the 1.x cycle.
Release goals
1.0
- features from 0.9
- bufixes
- upgrade path from any earlier 0.x release
0.2
Matches XO's "Update.1" release. Will be deployed in Peru - our first large-scale install of XSs, many of them with nil or spotty connectivity, so strong focus on install tools and manageability.
- Backups
- Install config
- Security scheme
- Manageability
