A new version of RISC OS 5 is today available via Castle’s Internet based update distribution software. RISC OS 5.11 contains bug fixes to the Iyonix’s ethernet networking driver, EtherK, to address a fault with stalling connections – as seen occasionally in ShareFS. The USB stack has been tweaked to support USB radio projects and similar software. The RISC OS Flash ROM image was also built using optimisations included in the latest publically available version of the Norcroft C/C++ compiler, as sold by Castle. RISC OS 5.11 is a stable release, unlike its earlier cousin 5.10, which saw the introduction of improved Nvidia card handling during the start up of the computer.
