Well... v.07 doesn't yet exist, but we have to express the fact that we 
are on the latest tree (similar to Debian's 'sid' DISTRO_NAME).

I vote for the 'next'.

I'll prepare the patch together with description in 
RECIPE-API-CHANGELOG.md as Henning suggested in previous email.

Regards,
Maxim.

FYI:

Latest reference manual 
(https://www.yoctoproject.org/docs/2.5.1/ref-manual/ref-manual.html#var-LAYERSERIES_COMPAT). 


defines LAYERSERIES_COMPAT:

<<<
Lists the versions of the OpenEmbedded-Core for which a layer is 
compatible. Using the LAYERSERIES_COMPAT variable allows the layer 
maintainer to indicate which combinations of the layer and OE-Core can 
be expected to work. The variable gives the system a way to detect when 
a layer has not been tested with new releases of OE-Core (e.g. the layer 
is not maintained).

To specify the OE-Core versions for which a layer is compatible, use 
this variable in your layer's conf/layer.conf configuration file. For 
the list, use the Yocto Project Release Name (e.g. sumo). To specify 
multiple OE-Core versions for the layer, use a space-separated list:

      LAYERSERIES_COMPAT_layer_root_name = "sumo rocko"

Note
Setting LAYERSERIES_COMPAT is required by the Yocto Project Compatible 
version 2 standard. The OpenEmbedded build system produces a warning if 
the variable is not set for any given layer.
See the "Creating Your Own Layer" section in the Yocto Project 
Development Tasks Manual.
