Porteus Kiosk 4.1.0 发布了，Porteus Kiosk 是轻量级的Linux操作系统，它基于 Gentoo Linux 但却被限制为只允许运行一个应用程序即 Firefox网 页浏览器。该浏览器被锁定从而阻止用户去改动设置或是下载安装其他软件。系统启动后，它自动调用 Firefox 并打开用户选定的起始页面（基础教程qkxue.net）。浏览器不保存历史记录或输入的口令，很多菜单功能也被禁用以提升安全程度（腾云科技ty300.com）。Firefox 每次重启时都会清空缓存，这样浏览器每次启动的都是一个无历史痕迹的会话。
本次发布一些提升及新特性：
Kiosk config can be hosted directly on Porteus Kiosk Server - no need to use 3rd party web hosting service anymore. Clients must be configured with ‘kiosk_config=‘ parameter and utilize ‘server://config_name‘ protocol.
Its possible to define custom persistence level for the guest‘s home folder.
Password manager allows remembering logins and passwords to the websites.
Default search engine for the browser has been changed to the Google. Its still possible to set DuckDuckGo engine if privacy is a top priority.
Linux kernel used in our system can be tweaked with the help of additional kernel parameters.
Its possible to control the slide duration (time between loading new image) for the screensaver slideshow.
Improved ‘managed bookmarks‘ function allows to define the bookmark name.
DMPS is no longer forced to turn off the monitor after 10 minutes of inactivity and you may set the time after which the monitor goes off.
Session idle parameter will restart whole session (Xorg) for the variants Cloud and ThinClient.
Added option to preserve persistent partition, perform a quick format or completely erease the hard drive before the installation is started.
Enabled bootsplash for the post installation ISO.
Many other bugfixes and improvements.
