Den specialiserade kommandoskalet GNU Rush 2.2 (Restricted User Shell) har sl\u00e4ppts, vilket \u00e4r avsett f\u00f6r anv\u00e4ndning i system med begr\u00e4nsad fj\u00e4rr\u00e5tkomst d\u00e4r anv\u00e4ndarens \u00e5tg\u00e4rder m\u00e5ste begr\u00e4nsas. Rush g\u00f6r det m\u00f6jligt att definiera vilka kommandoradsfunktioner anv\u00e4ndaren kan anv\u00e4nda och vilka resurser som tillhandah\u00e5lls (minnesstorlek, CPU-tid osv.). Till exempel kan Rush anv\u00e4ndas f\u00f6r att k\u00f6ra program p\u00e5 distans i ett chroot-milj\u00f6, vilket \u00f6kar s\u00e4kerheten vid \u00e5tkomst genom program som sftp-server eller scp, som som standard har tillg\u00e5ng till hela filsystemet. <\/p>\n

I det nya avsnittet finns m\u00f6jligheten att anv\u00e4nda statuskontroller f\u00f6r filer och kataloger i filsystemet (till exempel kan man nu kontrollera filtyper, beh\u00f6righeter och \u00e4gare av filer i reglerna). Formatet f\u00f6r alternativ f\u00f6r kontroll liknar arbetet med kommandot \"test\". Till exempel kan man anv\u00e4nda konstruktionen \"match -d \/var\/lock\/sd\" f\u00f6r att kontrollera att s\u00f6kv\u00e4gen existerar och pekar p\u00e5 en katalog. <\/p>\n

Dessutom har utg\u00e5van av verktyget GNU Pies 1.7 publicerats, avsett f\u00f6r samordning av start och k\u00f6rning av applikationer. Baserat p\u00e5 den angivna konfigurationen startar programmet k\u00f6rbara filer i bakgrunden, \u00f6vervakar deras utf\u00f6rande och m\u00f6jligg\u00f6r koppling av olika tillst\u00e5ndshanterare; till exempel kan det starta om programmet vid ett kraschat avslut, k\u00f6ra ett annat program eller skicka en avisering till administrat\u00f6ren. Dessutom kan GNU Pies anv\u00e4ndas som init-processen som k\u00f6rs f\u00f6rst under systemets uppstart och st\u00f6der formatet \/etc\/inittab. <\/p>\n

I den nya versionen av GNU Pies har metoden f\u00f6r att arbeta med konfigurationsfiler \u00e4ndrats. Den inbyggda preprocessorn har tagits bort och varje fil som anges i uttrycken \"#include\" och \"#include_once\" behandlas nu separat av en extern preprocessorn (tidigare avsl\u00f6jade den inbyggda preprocessorn f\u00f6rst alla substitutioner av \"#include\", och sedan behandlades resultatet med den externa preprocessorn m4 som en helhet). Nya diagnostiska uttryck \"#warning 'TEXT'\", \"#error 'TEXT'\" och \"#abend 'TEXT'\" har lagts till f\u00f6r att generera varningar och felutskrifter. <\/p>\n

Det kan ocks\u00e5 n\u00e4mnas att paketet GNU mailutils 3.14 har sl\u00e4ppts, vilket erbjuder bibliotek och verktyg f\u00f6r att utf\u00f6ra olika uppgifter relaterade till e-post, s\u00e5som analys av f\u00e4lt i meddelanden, arbete med e-postdatabaser (mailbox, maildrop, maildir), filtrering av meddelanden, extrahering av e-postadresser och URL:er, bearbetning av MIME-block, h\u00e4mtning av brev fr\u00e5n externa servrar<\/a> via protokollen IMAP4 och POP3 och skickande av meddelanden via protokollet SMTP, inklusive anv\u00e4ndning av TLS, SASL och GSSAPI. <\/p>\n

I den nya versionen av GNU mailutils har st\u00f6d f\u00f6r TLS skrivits om helt. Inst\u00e4llningen tls.handshake-timeout har lagts till f\u00f6r att ange timeout f\u00f6r TLS. Funktionen mu_mailbox_append_message_ext har lagts till f\u00f6r att l\u00e4gga till meddelanden i mailbox. I mailverktyget har kommandot unread (U) lagts till f\u00f6r att ta bort l\u00e4sningen av ett meddelande, och vid kopiering till en annan mailbox s\u00e4kerst\u00e4lls att statusen (l\u00e4st eller ol\u00e4st) bevaras. Koden f\u00f6r parser och skannrar har skrivits om, och nu kr\u00e4vs GNU bison och flex f\u00f6r sammans\u00e4ttning. M\u00f6jligheten att inkludera mime-typer i biblioteket libmailutils har lagts till. I Maildir och MH har speglingen av informationen om avs\u00e4ndaren, som \u00f6verf\u00f6rs i kommandot \"MAIL FROM\" under SMTP-sessionen, upph\u00f6rt i rubrikerna X-Envelope-Sender och X-Envelope-Date. Ist\u00e4llet sparas dessa uppgifter i rubrikerna Return-Path och Received.
