1.1. Phases of Support lifecycle

Type of support Notes
Active support A release that is being actively supported. Reported bugs and security issues are fixed and regular point releases are made.
Security fixes only A release that is supported for critical security issues only. Releases are only made on an as-needed basis.
End of life A release that is no longer supported. Users of this release should upgrade as soon as possible, as they may be exposed to unpatched security vulnerabilities.

2. Support options

WackoWiki users have two options available for support:

2.1. Community Support

WackoWiki is supported by an active community, on a volunteer basis. Repairs/enhancements are made (or accepted) by project contributors on a best-effort basis, with no guarantees of either resolution or timeliness.

2.2. Commercial support

Service-Level-Agreement (SLA)-based production support and value-added services for WackoWiki can be acquired directly from our Partners. Multiple companies providing services and products on top of the WackoWiki platform. Support contracts or new feature developments can be bought from service companies.
