Automatic BuddyPress language packs upgrade are getting the development version instead of 2.1.x one

[imath]

My personal website has BuddyPress 2.1.1 activated. I've just made a full back up of it and discovered that the po file header is :

# Translation of Development in French (France)
# This file is distributed under the same license as the Development package.
msgid ""
msgstr ""
"PO-Revision-Date: 2014-10-04 17:46:53+0000\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
"Plural-Forms: nplurals=2; plural=n > 1;\n"
"X-Generator: GlotPress/0.1\n"
"Project-Id-Version: Development\n"

Meaning all fr_FR sites are getting the "development strings" instead of the 2.1.x ones. I've just downloaded the 2.1.x po file on translate.wordpress.org and its header is :

# Translation of 2.1.x in French (France)
# This file is distributed under the same license as the 2.1.x package.
msgid ""
msgstr ""
"PO-Revision-Date: 2014-12-09 17:29:32+0000\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
"Plural-Forms: nplurals=2; plural=n > 1;\n"
"X-Generator: GlotPress/1.0-alpha-1000\n"
"Project-Id-Version: 2.1.x\n"

So 2.1.x revision date is "fresher" than development one

Is the fact that 2.1.x fr_FR is not completed at 100% could generate the download of the development version instead ?

The automatic translations updates language packs delivered have slightly different headers, they DO NOT actually include the version of BuddyPress, they are all listed as "Development Version"

via the Translation API the BP 2.1 headers match your details above, so fr_FR sites are in fact getting the correct BP 2.1 translations.

BuddyPress v2.1

And for reference, BuddyPress v2.0

The downloaded fr_FR .po file from ​https://translate.wordpress.org/projects/buddypress/2.1.x/fr/default/export-translations?format=po is generated from a different process/task thus the discrepancy in times.
