So what happens in 2.0.20 client-side? nothing much: - Switch from qt4 to qt5, should fix most new battle window problems - QR Code plugin there for Android - Translations fix - Teambuilder fix with Giratina-O in gen 4 - Hazards show in new battle window tooltip - Thai characters fixed - Added global ignore option for channels - Minor fixes This is significant though, because of the move to Qt5 and the QR Code plugin for Android. The Android app is just a step shy of beta, and soon going to be released on the market, and QRCodes is one of the ways to import a team - hence this release. Accessibility will definitely be in the plans now too. Serverside, some RBY bugs or general battle bugs are fixed, script function sys.os(playerId) can get you the OS of a player (so you can know who is on android). Android beta should be there in a day or two (or less!). Download page
From what I can tell, qt5 breaks transparency on buttons in themes :( Just in case anyone uses them and wonders why they have a big black box! Also Fusion looks terrible :( Also can the client be built in qt4 no problem? :< I might just do that :D
Yes, you can just have one new battle window open at the time. But yea, since linux client is still qt4.
If you installed your server in Program Files, make sure to run it in admin mode. Otherwise, I don't know, try to see if other people have that problem, if they do post in bugs & fixes.
