How are version numbers assigned in a software upgrade?
Software upgrade versioning is the process of assigning either unique version names or unique version numbers to unique states of computer software. Within a given version number category (major, minor), these numbers are generally assigned in increasing order and correspond to new developments in the software.
How to maintain different versions of the same code?
Modularize the common code, and implement the code that differs in different files or guard it with different defines. Make your build system have specific targets for each client, each target compiling a version with only the code related to one client.
Is the Protocol version number the same as the software version number?
Often packet headers and file format include a version number – sometimes the same as the version number of the software that wrote it; other times a “protocol version number” independent of the software version number. The code to handle old deprecated protocols and file formats is often seen as cruft.
How are version numbers used in open source software?
This is a common convention in open source software. However, if the pre-release version is for an existing software package (e.g. version 2.5), then an “a” or “alpha” may be appended to the version number. So the alpha version of the 2.5 release might be identified as 2.5a or 2.5.a.
What is the definition of semantic versioning in software?
Degree of compatibility. Semantic Versioning is a formal convention for specifying compatibility using a three-part version number: major version; minor version; and patch. The patch number is incremented for minor changes and bug fixes which do not change the software’s application programming interface (API).
How are breaking changes indicated in software versioning?
Breaking changes are indicated by increasing the major number (high risk), new non-breaking features increment the minor number (medium risk) and all other non-breaking changes increment the patch number (lowest risk).
