Se pueden usar ssh, rsh o el propio protocolo rsync como transporte. Se admite la organizaci\u00f3n del trabajo con servidores rsync an\u00f3nimos, \u00f3ptimos para garantizar la sincronizaci\u00f3n de espejos. El c\u00f3digo del proyecto se distribuye bajo la licencia GPLv3.    <\/p>\n<p>Entre los cambios a\u00f1adidos:  <\/p>\n<ul>\n<li class=\"l\"> Se ha propuesto un nuevo m\u00e9todo de protecci\u00f3n para argumentos de l\u00ednea de comandos, que recuerda a la opci\u00f3n anteriormente disponible \u00ab\u2014protect-args\u00bb (\u00ab-s\u00bb), pero que no interrumpe el funcionamiento del script rrsync (rsync restringido). La protecci\u00f3n consiste en escapar caracteres especiales, incluidos los espacios, al pasar solicitudes al int\u00e9rprete de comandos externo. El nuevo m\u00e9todo no escapa los caracteres especiales dentro de un bloque delimitado por comillas, lo que permite utilizar una simple delimitaci\u00f3n del nombre del archivo entre comillas sin necesidad de un escape adicional; por ejemplo, ahora se permite el comando \u00abrsync -aiv host:'un archivo simple.pdf' .\u00bb. Para restaurar el comportamiento antiguo, se ha propuesto la opci\u00f3n \u00ab\u2014old-args\u00bb y la variable de entorno \u00abRSYNC_OLD_ARGS=1\u00bb.\n<li class=\"l\"> Se ha solucionado un antiguo problema con el manejo de caracteres de coma decimal teniendo en cuenta la configuraci\u00f3n regional actual (\u00bb,\u00ab en lugar de \u00ab.\u00bb. Para scripts que se basan en el uso exclusivo del car\u00e1cter \u00ab.\u00bb en los n\u00fameros, en caso de incompatibilidad se puede establecer la configuraci\u00f3n regional en \u00abC\u00bb.\n<li class=\"l\"> Se ha corregido una vulnerabilidad (CVE-2018-25032) en el c\u00f3digo incluido de la biblioteca zlib, que provoca un desbordamiento de b\u00fafer al intentar comprimir una secuencia de caracteres espec\u00edficamente preparada.\n<li class=\"l\"> Se ha implementado la opci\u00f3n \u00ab\u2014fsync\u00bb para llamar a la funci\u00f3n fsync() en cada operaci\u00f3n de archivo con el fin de vaciar la cach\u00e9 del disco.\n<li class=\"l\"> En el script rsync-ssl se ha activado la opci\u00f3n \u00ab-verify_hostname\u00bb al acceder a openssl.\n<li class=\"l\"> Se ha a\u00f1adido la opci\u00f3n \u00ab\u2014copy-devices\u00bb para copiar archivos de dispositivos como archivos normales.\n<li class=\"l\"> Se ha reducido el consumo de memoria durante la transferencia incremental de un gran n\u00famero de peque\u00f1os directorios.\n<li class=\"l\"> En la plataforma macOS se ha garantizado el funcionamiento de la opci\u00f3n \u00ab\u2014atimes\u00bb.\n<li class=\"l\"> Se ha implementado la posibilidad de actualizar los atributos xattrs para archivos en modo de solo lectura, si el usuario tiene permisos para cambiar los derechos de acceso (por ejemplo, al ejecutarse con privilegios de root).\n<li class=\"l\"> Se ha a\u00f1adido y activado por defecto el par\u00e1metro \u00ab\u2014info=NONREG\u00bb para mostrar advertencias sobre la transferencia de archivos especiales.\n<li class=\"l\"> El script rrsync (rsync restringido) se ha reescrito en el lenguaje Python. Se han a\u00f1adido nuevas opciones \u00ab-munge\u00bb, \u00ab-no-lock\u00bb y \u00ab-no-del\u00bb. Por defecto, se incluye el bloqueo de las opciones \u00ab\u2014copy-links\u00bb (-L), \u00ab\u2014copy-dirlinks\u00bb (-k) y \u00ab\u2014keep-dirlinks\u00bb (-K) para dificultar la realizaci\u00f3n de ataques que manipulan enlaces simb\u00f3licos a directorios.\n<li class=\"l\"> El script atomic-rsync ha sido reescrito en Python y ampliado para ignorar c\u00f3digos de retorno diferentes de cero. Por defecto, se ignora el c\u00f3digo 24, que se devuelve cuando faltan archivos durante la ejecuci\u00f3n de rsync (por ejemplo, el c\u00f3digo 24 se devuelve para archivos temporales que estaban presentes durante la indexaci\u00f3n inicial, pero que fueron eliminados para el momento de la transferencia).\n<li class=\"l\"> El script munge-symlinks ha sido reescrito en Python.
