[Telepathy] Getting rpm/source of development version

[Piotr Dobrogost]

Hi,

I'd like to install version of Telepathy with the following changeset
"Don't leave group chat when window is closed"
(https://git.reviewboard.kde.org/r/117543/ ,
https://projects.kde.org/projects/extragear/network/telepathy/ktp-text-ui/repository/show?branch=master&tag=&rev=5506ceed15fdd88b47a6f2715587bfcba8c532fa
)
How can I do this?
How do I know which versions of other libs/components ktp-text-ui needs?
Is there any rpm with current development version?
How can I see what earliest version some specific changeset will be included in?

I currently have ktp-text-ui in version 0.9.0 and I'm on Fedora 21.


Thank you in advance.

Regards,
Piotr Dobrogost
