Thanks for answering @charlie.brooker ,
What you said is correct. The version number that @hzamani_i2c is seeing in the warning is the version of honeybee-schema that is currently installed, which is basically the version of the HBJSON file format that is being used. This is totally separate from the LBT Grasshopper version or the version of any component.
Like you said, Charlie - you can probably ignore the warning, @hzamani_i2c , if you’re not using any particular new features of Honeybee like those in the last release (eg. window frames). The two versions of honeybee-schema are not that far apart. But the warning is just telling you that the HBJSON file format has had some changes/additions to it since the time when Ladybug Tools was installed on that machine.
If you are concerned about it, then running the LB Versioner component without anything connected to version_ will make sure that your plugin updates to the latest development version of LBT Grasshopper (including the latest honeybee-schema). This will ensure everything about the HBJSON is loaded correctly.
