Kutulutsidwa kwa nsanja yotseguka ya webOS Open Source Edition 2.20 kwayambitsidwa, yomwe ingagwiritsidwe ntchito pazida zosiyanasiyana zonyamula, ma board ndi ma infotainment system yamagalimoto. Ma board a Raspberry Pi 4 amaonedwa ngati nsanja ya zida zowunikira. Pulatifomu imapangidwa pamalo osungira anthu pansi pa layisensi ya Apache 2.0, ndipo chitukuko chimayang'aniridwa ndi anthu ammudzi, kutsatira njira yoyendetsera chitukuko chogwirizana.
Tsamba la webOS lidapangidwa koyambirira ndi Palm mu 2008 ndipo linagwiritsidwa ntchito pa mafoni a m'manja a Palm Pre ndi Pixie. Mu 2010, pambuyo pa kulandidwa kwa Palm, nsanjayo inadutsa m'manja mwa Hewlett-Packard, pambuyo pake HP anayesa kugwiritsa ntchito nsanjayi mu osindikiza ake, mapiritsi, laputopu ndi ma PC. Mu 2012, HP idalengeza kumasuliridwa kwa webOS kukhala pulojekiti yodziyimira payokha yotseguka ndipo mu 2013 idayamba kutsegula magwero azinthu zake. Mu 2013, nsanja idagulidwa kuchokera ku Hewlett-Packard ndi LG ndipo tsopano ikugwiritsidwa ntchito pa ma TV opitilira 70 miliyoni a LG ndi zida za ogula. Mu 2018, pulojekiti ya webOS Open Source Edition idakhazikitsidwa, pomwe LG idayesa kubwereranso kuchitsanzo chachitukuko chotseguka, kukopa otenga nawo gawo ndikukulitsa zida zosiyanasiyana zothandizidwa ndi webOS.
Mawonekedwe a webOS amapangidwa pogwiritsa ntchito zida za OpenEmbedded ndi phukusi loyambira, komanso njira yomanga ndi seti ya metadata kuchokera ku polojekiti ya Yocto. Zigawo zazikulu za webOS ndi system and application manager (SAM, System and Application Manager), yomwe ili ndi udindo woyendetsa mapulogalamu ndi ntchito, ndi Luna Surface Manager (LSM), yomwe imapanga mawonekedwe ogwiritsira ntchito. Zidazi zimalembedwa pogwiritsa ntchito Qt framework ndi Chromium browser injini.
Kupereka kumachitika kudzera mwa woyang'anira gulu pogwiritsa ntchito protocol ya Wayland. Kuti mupange mapulogalamu achizolowezi, akuyenera kugwiritsa ntchito matekinoloje a pa intaneti (CSS, HTML5 ndi JavaScript) ndi ndondomeko ya Enact, yochokera ku React, komanso ndizotheka kupanga mapulogalamu mu C ndi C ++ ndi mawonekedwe a Qt. Chigoba cha ogwiritsa ntchito ndi zojambulidwa zomangidwa mkati zimakhazikitsidwa makamaka ngati mapulogalamu achilengedwe olembedwa pogwiritsa ntchito ukadaulo wa QML. Chipolopolo cha Home Launcher chokhazikika chimakonzedwa kuti chiziwongoleretsa pazenera ndipo chimapereka lingaliro la mamapu ozungulira (m'malo mwa windows).
Kusunga deta mu mawonekedwe opangidwa pogwiritsa ntchito mawonekedwe a JSON, DB8 yosungirako imagwiritsidwa ntchito, pogwiritsa ntchito database ya LevelDB monga backend. Bootd imagwiritsidwa ntchito poyambitsa kutengera systemd. Ma subsystem a uMediaServer ndi Media Display Controller (MDC) amaperekedwa kuti azitha kukonza zinthu zambiri; PulseAudio imagwiritsidwa ntchito ngati seva yamawu. Kuti musinthe firmware, OSTree ndi atomic partition m'malo amagwiritsidwa ntchito (magawo awiri amapangidwa, imodzi yomwe imagwira ntchito, ndipo yachiwiri imagwiritsidwa ntchito kukopera zosintha).
Zosintha zazikulu pakutulutsa kwatsopano:
- Kupereka kwa zithunzi zopangidwa kale za webOS za board ya Raspberry Pi 4 ndi emulator kwayamba. Zithunzizi zidzatumizidwa ku GitHub m'masiku ochepa atatulutsidwa.
- Mawonekedwe ogwiritsira ntchito makina asinthidwa kuchoka ku Moonstone framework kupita ku Sandstone.
- Wokonza amapereka mwayi wowona mndandanda wa malo odziwika a Wi-Fi omwe maulumikizidwe adapangidwapo kale.
- Onjezani njira yachidule ya kiyibodi (Ctrl + Alt + F9) kuti mupange chithunzi (chosungidwa mu /tmp/screenshots), komanso njira yachidule Ctrl + Alt + F10 kuti muchotse zowonera zonse.
- Mafano osinthidwa mu bar yamasitepe. Adawonjezera kuthekera kolumikizana ndi Wi-Fi kuchokera pagawo lapamwamba.
- WebEX Browser yawonjezera kanema kapena chowonera pamasewera.
- Clang amagwiritsidwa ntchito kupanga webruntime ndi WAM mu injini ya Blink.
