 ### pre-release-weight
-Provides a way to translate the `PreReleaseLabel` ([variables](/more-info/variables)) to a numeric value in order to avoid version collisions across different branches. For example, a release branch created after "1.2.3-alpha.55" results in "1.2.3-beta.1" and thus e.g. "1.2.3-alpha.4" and "1.2.3-beta.4" would have the same file version: "1.2.3.4". One of the ways to use this value is to set `assembly-file-versioning-format: {Major}.{Minor}.{Patch}.{WeightedPreReleaseNumber}`. If the `pre-release-weight` is set, it would be added to the `PreReleaseNumber` to get a final `AssemblySemFileVer`, otherwise a branch specific default for `pre-release-weight` will be used in the calculation.
