lupdate: File ... won't be updated: it contains translation but the target language is not recognized

Hi,
I have upgraded Qt Creator to 4.10 beta and got this message when trying to update translations. Any ideas what does it mean? Everything worked fine before the upgrade.
Thanks

@Hitokage OK looks like the new lupdate version needs additional info about the file's language so I had to add something like this:

<TS version="2.1" language="cs_CZ">

Works now!
