-Versioning
-----------
-
-Puppeteer versions as regularly released from the Python source code, will follow
-a specific versioning schema. It means the major version number will always
-be identical with the supported Firefox version. Minor releases - the second part
-of the version number - are done throughout the life-cycle of a Firefox version
-when Puppeteer itself needs API changes for back-end and front-end modules. The
-last part of the version number is the patch level, and is only used for bugfix
-releases without any API changes.
-
-Examples:
-
-  firefox_puppeteer_45.0.0 - First release for Firefox 45.0 and Firefox 45.xESR
-  firefox_puppeteer_46.2.0 - Second release for Firefox 46.0 caused by API changes
-  firefox_puppeteer_47.0.1 - First bugfix release for the new Firefox 47.0 support
