# OpenVR Advanced Settings Developer Docs For things that don't directly belong a single place in the source code. > * [New Patch Release Checklist](#patch_checklist) > * [Increment Version Numbers](#inc_vers_numbers) ## New Patch Release Checklist ### Increment Version Numbers Currently there are three version strings in the source. 1. `src\overlaycontroller.h` - Variable named `applicationVersionString`. 2. `build_scripts\win\common.py` - Variable named `VERSION_STRING`. 3. `installer\installer.nsi` - Variable named `VERSION_STRING`. The first string should be three digits separated by dots (periods), as described in [semantic versioning](https://semver.org/) (like "2.8.0"). The second and third should be three digits separated by hyphens/dashes (like "2-8-0"). The reason for the difference is that the first string is only used as a string in the source code, while the second and third are used to name files. Some operating system can become confused with more than one dot in the file name (like Windows). It's better to just avoid the situation entirely.
