De <noindex><a rel=\"nofollow\" href=\"https:\/\/git.archlinux.org\/pacman.git\/tree\/NEWS?h=v5.2.0\">cambios<\/a><\/noindex> se pueden destacar:<\/p>\n<ul>\n<li class=\"l\"> Se ha eliminado por completo el soporte para actualizaciones delta, que permit\u00edan descargar solo los cambios. Esta opci\u00f3n se elimin\u00f3 debido a la detecci\u00f3n de una vulnerabilidad (<noindex><a rel=\"nofollow\" href=\"https:\/\/security.archlinux.org\/CVE-2019-18183\">CVE-2019-18183<\/a><\/noindex>), que permit\u00eda la ejecuci\u00f3n de comandos arbitrarios en el sistema al utilizar bases de datos no firmadas. Para el ataque, el usuario deb\u00eda cargar archivos manipulados con base de datos y actualizaciones delta. El soporte para actualizaciones delta se desactiv\u00f3 por defecto y no tuvo gran difusi\u00f3n. En el futuro se planea reescribir completamente la implementaci\u00f3n de actualizaciones delta;\n<li class=\"l\"> En el manejador de comandos XferCommand se ha corregido una vulnerabilidad (<noindex><a rel=\"nofollow\" href=\"https:\/\/security.archlinux.org\/CVE-2019-18182\">CVE-2019-18182<\/a><\/noindex>), que permit\u00eda, en un ataque MITM y con bases de datos no firmadas, lograr la ejecuci\u00f3n de comandos no autorizados en el sistema;\n<li class=\"l\"> En makepkg se agreg\u00f3 la posibilidad de incluir manejadores para descargar paquetes fuente y verificar mediante firma digital. Se a\u00f1adi\u00f3 soporte para la compresi\u00f3n de paquetes utilizando los algoritmos lzip, lz4 y zstd. En repo-add se a\u00f1adi\u00f3 soporte para comprimir bases de datos utilizando zstd. En breve, Arch Linux <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=51687\">se espera<\/a><\/noindex> el cambio por defecto para usar zstd, que en comparaci\u00f3n con el algoritmo \u00abxz\u00bb permitir\u00e1 acelerar las operaciones de compresi\u00f3n y descompresi\u00f3n de paquetes, manteniendo al mismo tiempo el nivel de compresi\u00f3n;\n<li class=\"l\"> Se garantiza la posibilidad de compilaci\u00f3n utilizando el sistema Meson en lugar de Autotools. En la siguiente versi\u00f3n, Meson reemplazar\u00e1 completamente a Autotools;\n<li class=\"l\"> Se a\u00f1adi\u00f3 soporte para la carga de claves PGP utilizando el mecanismo <noindex><a rel=\"nofollow\" href=\"https:\/\/wiki.gnupg.org\/WKD\">Directorio de Claves Web<\/a><\/noindex> (WKD), cuya funci\u00f3n principal es el almacenamiento de claves p\u00fablicas en la web vinculadas al dominio especificado en la direcci\u00f3n de correo.

La carga de claves a trav\u00e9s de WKD est\u00e1 habilitada por defecto en pacman, pacman-key y makepkg;\n<li class=\"l\"> Se ha eliminado la opci\u00f3n \u00ab--force\u00bb, que fue reemplazada hace m\u00e1s de un a\u00f1o por una opci\u00f3n que refleja m\u00e1s precisamente la esencia de la operaci\u00f3n: \u00ab--overwrite\u00bb;\n<li class=\"l\"> En los resultados de b\u00fasqueda de archivos
