Thanks. But I have already build and install the PKGBUILD by myself.
But for other (inexperienced) user switching to unstable / building the PKGBUILD is not an option.
It definitely is, three valid options (Testing branch, Unstable branch, building the package youself) while waiting for the package to reach Stable branch. Only very important packages have special treatment and got fast tracked to Stable (browsers, security updates, things like that).

You appear to have a very low expectation of new user capabilities
A new user can copy/paste 2 commands from Manjaro wiki to switch branches
Only one command would be needed to build new package but command has not been posted here for new users to copy/paste
If a user considers both options are beyond their capabilities to attempt they should follow this discussion
(click the green bell icon on the right and change status to Watching)
When new version is available in stable repository I will confirm here before closing topic
