| The first OpenWrt versions were based on Linksys GPL sources for WRT54G and a buildroot from the uClibc project. | The first OpenWrt versions were based on Linksys GPL sources for WRT54G and a buildroot from the [[wp>uClibc|uClibc]] project. |
| This version was known as OpenWrt "stable release" and was widely in use. There are still many OpenWrt applications, like the Freifunk-Firmware or Sip@Home, which are based on this version. | This version was known as OpenWrt stable release and was widely in use. |
| |
| In the beginning of 2005 some new developers joined the team. After some months of closed development the team decided to publish the first "experimental" versions of OpenWrt. The experimental versions use a heavily customized build system based on buildroot2 from the uClibc project. | In the beginning of 2005 some new developers joined the team. |

| |
| OpenWrt uses official GNU/Linux kernel sources and only adds patches for the system on chip and drivers for the network interfaces. The developer team tries to re-implement most of the proprietary code inside the GPL tarballs of the different vendors. There are free tools for writing new firmware images directly into the flash (mtd), for configuring the wireless lan chip and to program the VLAN-capable switch via the proc filesystem. | OpenWrt uses official GNU/Linux kernel sources and only adds patches for the system on chip and drivers for the network interfaces. |
