I found an entry in skin.conf missing in en.conf:
For German:
[HistoryReport]
monthnames = Jan, Feb, Mar, Apr, Mai, Jun, Jul, Aug, Sep, Okt, Nov, Dez
and some translations for Beaufort as text version would also be helpful.
Here is my german version, used in current.inc:
#if $varExists('day.windSpeed') and $current.windSpeed.raw is not None
#if $current.windSpeed.beaufort.raw == 0
#set $word_current_beaufort = 'Windstille'
#elif $current.windSpeed.beaufort.raw == 1
#set $word_current_beaufort = 'Leiser Zug'
#elif $current.windSpeed.beaufort.raw == 2
#set $word_current_beaufort = 'Leichte Brise'
#elif $current.windSpeed.beaufort.raw == 3
#set $word_current_beaufort = 'Schwache Brise'
#elif $current.windSpeed.beaufort.raw == 4
#set $word_current_beaufort = 'Mäßige Brise'
#elif $current.windSpeed.beaufort.raw == 5
#set $word_current_beaufort = 'Frische Brise'
#elif $current.windSpeed.beaufort.raw == 6
#set $word_current_beaufort = 'Starker Wind'
#elif $current.windSpeed.beaufort.raw == 7
#set $word_current_beaufort = 'Steifer Wind'
#elif $current.windSpeed.beaufort.raw == 8
#set $word_current_beaufort = 'Stürmischer Wind'
#elif $current.windSpeed.beaufort.raw == 9
#set $word_current_beaufort = 'Sturm'
#elif $current.windSpeed.beaufort.raw == 10
#set $word_current_beaufort = 'Schwerer Sturm'
#elif $current.windSpeed.beaufort.raw == 11
#set $word_current_beaufort = 'Orkanartiger Sturm'
#elif $current.windSpeed.beaufort.raw == 12
#set $word_current_beaufort = 'Orkan'
#else
#set $word_current_beaufort = 'N/A'
#end if
And, well, the modules, I have in use, alltime seasons and forecast, which have their own extra labelling text built in, are always a pain to keep them uptodate with seasons skin. Adopting all kind of those modules to the new version might be laborious and take some time. Sigh...
