Hello Nordic,
Please don't change the format of nRF Connect SDK version number from v2.2.0 to v2.2.99-dev3. v2.2.99 is fine but no v2.2.99-dev3. The dev2, dev3, dev 4 are not number and it breaks the format and built tools and build scripts which expecting and parsing numbers. If you need a new version number, just pump it up to v2.3.0 or v2.3.1. Thanks.
