kutulutsidwa kwa library (Simple Direct Layer), cholinga chake ndikuchepetsa kulemba kwamasewera ndi ma multimedia application. Laibulaleyi imapereka zida monga kutulutsa kwazithunzi za 2D ndi 3D za Hardware, kukonza zolowetsa, kusewera mawu, kutulutsa kwa 3D kudzera pa OpenGL/OpenGL ES ndi ntchito zina zambiri zofananira. Laibulale imalembedwa mu C ndipo imagawidwa pansi pa chilolezo cha zlib. Zomangiriza zimaperekedwa kuti zigwiritse ntchito mphamvu za SDL pamapulojekiti azilankhulo zosiyanasiyana zamapulogalamu.
M'kutulutsa kwatsopano:
- Dalaivala wogwira ntchito pogwiritsa ntchito seva yowonetsera ya Mir wachotsedwa mokomera woyendetsa ntchito kudzera pa Wayland;
- Ma SDL_RW* macros asinthidwa kukhala magawo osiyana;
- Anawonjezera SDL_SIMMDGetAlignment(), SDL_SIMDAlloc() ndi SDL_SIMDFree() ntchito kugawa kukumbukira kwa ntchito SIMD;
- Zowonjezera SDL_RenderDrawPointF(), SDL_RenderDrawPointsF(), SDL_RenderDrawLineF(), SDL_RenderDrawLinesF(), SDL_RenderDrawRectF(), SDL_RenderDrawRectsF(), SDL_RenderFillRectF(SDLFDLRectF)(SDLFDLRectF) nderCopyExF () poyandama popereka API SDL;
- Anawonjezera SDL_GetTouchDeviceType() ntchito kuti mudziwe mtundu wa chipangizo chokhudza (touchpad kapena touchscreen yokhala ndi wachibale kapena mtheradi);
- SDL rendering API yasinthidwa kuti igwiritse ntchito batch rendering mwachisawawa, kulola kuchita bwino. Kuti muwongolere kagwiritsidwe ntchito ka batch mode, njira ya SDL_HINT_RENDER_BATCHING yawonjezedwa;
- Onjezani foni ku SDL_RenderFlush() kuti ikakamize maulamuliro am'mizere kuti achite, zomwe zingakhale zothandiza pophatikiza kupereka kwa SDL ndi kumasulira mwachindunji;
- Njira yowonjezerera SDL_HINT_EVENT_LOGGING kuti mutsegule mitengo ya zochitika za SDL kuti zithetse;
- Njira yowonjezera SDL_HINT_GAMECONTROLLERCONFIG_FILE kuti muyike dzina lafayilo ndi masanjidwe a owongolera masewera;
- Njira yowonjezera ya SDL_HINT_MOUSE_TOUCH_EVENTS kuti muwongolere kaphatikizidwe ka zochitika zokhuza kutengera zochitika za mbewa;
- Kusintha kwabwino kwamafayilo opangidwa molakwika a WAVE ndi BMP kuti aletse kuthekera ;
- Kwa iOS 13 ndi tvOS 13, chithandizo cha olamulira opanda zingwe a Xbox ndi PS4 awonjezedwa, komanso kuthandizira kulowetsa mawu pogwiritsa ntchito makibodi a Bluetooth;
- chifukwa Android Njira yochepetsera mawu yomwe ili ndi latency yochepa yakhazikitsidwa pogwiritsa ntchito OpenSL ES. Njira ya SDL_HINT_ANDROID_BLOCK_ON_PAUSE yawonjezedwa kuti iwongolere ngati kuzungulira kwa chochitikacho kwatsekedwa pulogalamuyo ikayimitsidwa.
