Kutulutsidwa kwa nthambi yokhazikika ya Tor 0.4.0

adawona kuwala kumasulidwa kwa zida Tor 0.4.0.5, yomwe imagwiritsidwa ntchito kukonza magwiridwe antchito a netiweki ya Tor yosadziwika. Tor 0.4.0.5 imadziwika ngati kutulutsidwa kokhazikika kwa nthambi ya 0.4.0, yomwe yakhala ikukula kwa miyezi inayi yapitayi. Nthambi ya 0.4.0 idzasungidwa ngati gawo la kayendetsedwe ka nthawi zonse - zosintha zidzathetsedwa pakatha miyezi 9 kapena miyezi 3 pambuyo pa kutulutsidwa kwa nthambi ya 0.4.1.x. Thandizo la nthawi yayitali (LTS) limaperekedwa ku nthambi ya 0.3.5, zosintha zomwe zidzatulutsidwa mpaka February 1, 2022.

Zatsopano zazikulu:

• Pakukhazikitsa gawo la kasitomala anawonjezera njira yopulumutsira mphamvu - pakusagwira ntchito kwanthawi yayitali (maola 24 kapena kupitilira apo), kasitomala amagona, pomwe ntchito za netiweki zimayima ndipo zida za CPU sizimagwiritsidwa ntchito. Kubwerera kumayendedwe abwinobwino kumachitika pambuyo popempha wogwiritsa ntchito kapena atalandira lamulo lowongolera. Kuti muwongolere kuyambiranso kwa kugona mutatha kuyambiranso, dongosolo la DormantOnFirstStartup laperekedwa (kubwerera kumayendedwe ogona nthawi yomweyo, osadikirira maola ena 24 osagwira ntchito);
• Tsatanetsatane wa njira yoyambira ya Tor (bootstrap) yakhazikitsidwa, kukulolani kuti muwunikire zifukwa zochedwetsa poyambira osadikirira kuti kulumikizana kumalize. M'mbuyomu, zidziwitso zidawonetsedwa pokhapokha kulumikizana kumalizidwa, koma njira yoyambirayo imatha kuzizira kapena kutenga maola kuti amalize m'mabvuto ena, zomwe zidapangitsa kuti pakhale kusatsimikizika. Pakalipano, mauthenga okhudzana ndi zovuta zomwe zikungoyamba kumene komanso momwe zimayambira zimawonekera pamene kupita patsogolo kwa magawo osiyanasiyana kukupita patsogolo. Payokha, zidziwitso zokhudzana ndi momwe kulumikizana kugwiritsidwira ntchito ndi ma proxies ndi zoyendera zolumikizidwa zimawonetsedwa;
• Zakhazikitsidwa chithandizo choyamba adaptive yowonjezera padding (WTF-PAD - Adaptive Padding) kuti athane ndi njira zosalunjika zodziwira zowona zopezeka pamasamba ndi mautumiki obisika kudzera pakuwunika mawonekedwe akuyenda kwa paketi ndi kuchedwa pakati pawo, mawonekedwe amasamba ndi mautumiki ena. Kukhazikitsaku kumaphatikizapo makina owerengeka a boma omwe amagwira ntchito pogawa ziwerengero kuti asinthe kuchedwa pakati pa mapaketi kuti aziyenda bwino. Njira yatsopanoyi imagwira ntchito poyeserera pakadali pano. Pakali pano padding-level padding ndi ntchito;
• Onjezani mndandanda womveka bwino wama subsystems a Tor omwe adayitanidwa kuti ayambitse ndi kutseka. M'mbuyomu, ma subsystems amayendetsedwa kuchokera kumalo osiyanasiyana mu code base ndipo kugwiritsa ntchito kwawo sikunapangidwe;
• API yatsopano yakhazikitsidwa poyang'anira njira za ana, kulola njira yolumikizirana yolumikizirana pakati pa njira za ana pa machitidwe ngati Unix ndi pa Windows.
