Hi all.
I completed the translation of new words in the localization files of
Venetian language, also making errors correction. I need to apply these
changes to the following versions of LibreOffice: 5.1, 5.2 and 5.3.
Thank you.

Hi Veneto,

Hi all.
I completed the translation of new words in the localization files of
Venetian language, also making errors correction. I need to apply these
changes to the following versions of LibreOffice: 5.1, 5.2 and 5.3.

5.1 is already EOL so no chance to have a version in this branch, next
versions will be 5.2.7 and 5.3.3 beginning of May

Cheers
