= Versions of BOINC =

The BOINC software (including client and server components) evolve over time. There are a number of pairwise interactions in which version mismatches could cause problems:

 * RPC from core client to scheduling server.
 * RPC from core client to file upload handler.
 * Interface between core client and application.
 * Interface between BOINC DB and all BOINC back-end components.
 * The parsing of the core state file by the core client. 

Each BOINC software component has a version consisting of three integers: major, minor, and release.

Some changes to the BOINC server software may involve changes to the BOINC database (e.g. adding a new table or field). Such releases will include SQL script for modifying an existing database in-place.
