Unincorporated area
In law, an unincorporated area is a region of land that is not governed by a local municipal corporation; similarly an unincorporated community is a settlement that is not governed by its own local municipal corporation, but rather is administered as part of larger administrative divisions, such as a township, parish, borough, county, city, canton, state, province or country. Occasionally, municipalities dissolve or disincorporate, which may happen if they become fiscally insolvent, and services become the responsibility of a higher administration. Widespread unincorporated communities and areas are a distinguishing feature of the United States and Canada. In most other countries of the world, there are either no unincorporated areas at all, or these are very rare; typically remote, outlying, sparsely populated or uninhabited areas.
Unofficial patch
In the computer game domain, where unofficial patches are most common, unofficial patches are also sometimes called "Fan patches", especially if produced by an individual person. Combined patches, including the work of several developers and authors from the community, are also called "Community Patch". They are aiming typical for critical bugs in the program flow which could lead to program crashes and technical compatibility fixes, e.g. for newer operating systems, increased display resolutions or new display formats.
