Please read Disclaimer before using this framework.

Versioning policy

[major].[minor].[micro]

  • major version part - changes on dramatic technological platform changes
  • minor version part - changes require a few lines of additional code to make it work
  • micro version part - changes do not require additional code to make it work

update 4.17.1 -> 4.17.3 - should not require any additional code
update 4.17.10 -> 4.18.0 - should require some additional code

Absence of the code required for new mior version may not break an application compeletely. But it may cause partial degradation. Please, pay attention to check the app is working properly on such updates
