@khannarhea looks good to me.

[MikhailTryakhov]

@christiankuhtz @khannarhea this is a breaking change. by some reason SDK is still not releseased and we'll include this info there. but next time it'll be very bad to push such changes in next SDK version it'll cause problems. Can we be sure your swagger is ready?

[MikhailTryakhov]

@khannarhea please push changes to master branch as well to avoid breaking changes in SDKs

[sergey-shandar]

@khannarhea @MikhailTryakhov why the changes for 2018-07-01 are targeting September branch (2018-08-01)? IMHO, it should target master.

[MikhailTryakhov]

@sergey-shandar you're right. @khannarhea please retarget it to master branch
