Lubuntu 14.10 was released.
"A new version of our operating system has been released. You won't notice many cosmetic changes, as this version is considered as a bug-fix release, preparing the way to meet LXQt. Here are some changes: general bug-fix release as we prepare for LXQt; many LXDE components have been updated with bug-fix releases; an update of the artwork (more icons, theme update, more compatibilities); the Ubuntu 14.10 release with 3.16-based kernel; Firefox is updated to version 33; GTK+ updated to version 3.12; X.Org 1.16 has better support for non-PCI devices."
Lubuntu is a fast, lightweight and energy-saving variant of Ubuntu using the LXDE (Lightweight X11 Desktop Environment) desktop. It is intended to have low-resource system requirements and is designed primarily for netbooks, mobile devices and older PCs.
