= Release Notes for HelenOS mainline = HelenOS ''0.7.1 (Enlightened Zeal)'' was released on ''November 12, 2017''. This document contains a summary of changes made to HelenOS since release [wiki:ReleaseNotes/0.7.0 0.7.0]. == Special Notes for this Release == * HelenOS is still an experimental operating system at this point in time and support for many platforms and hardware devices is not production-ready. For the time being, the agile 6-month release cycle might therefore produce releases that are slightly less "polished" in certain aspects, but it is also a driving force towards turning HelenOS into a production-ready operating system in the near future. == Features Introduced in This Release == === General === * This is the last release which uses the Bazaar version control system (VCS). Future releases will use Git. * The system can again be built by clang for amd64 === Kernel === * Basic support for capabilities * IPC phones have in fact been a sort of capabilities since the beginning. This work generalizes some of the IPC code to support more kernel object types. * IRQ structures are now managed using capabilities. It is no longer possible to unregister someone else's IRQ. * The limit of 64 IPC phones has been removed and is now virtually infinite. * The kernel is now using the resizable hash table which has been already used in uspace since 2012. === Services and Drivers === * The naming service was converted to use the async framework * CUDA driver was converted to the Device Driver Framework * The interrupt controller drivers were converted to using the Device Driver Framework * User can now unload an idle driver using `devctl unload-drv` * Framebuffer now gets mapped only when actually used === File Systems === * All file system operations are relative to a specified node, client-side root * Mountpoints are no longer stored in the filesystem servers, but in VFS * Inbox mechanism for passing files from parent to a new child * Client-side I/O cursors (file positions) * Overhaul of the [wiki:FilesystemAPITutorial client interface]; all APIs begin with the vfs_ prefix and can be used after including vfs/vfs.h * Removal of some POSIX-ish headers and definitions * File system probing * Volume label support === Networking === * Lots of networking fixes in TCP, DNS and HTTP protocols * TCP unit tests === Applications === * The `pkg` utility was added which allows installing packages from [http://ci.helenos.org/latest/ ci.helenos.org] into a running instance of HelenOS === Libraries === * Effort towards greater C11 compliance and a cleaner cut between HelenOS-specific, C11 and POSIX code * io/table module to print tabular output (used by devctl, inet). === Miscellaneous === == Fixed Logged Bugs & Enhancements == * For the list of all logged defects fixed in this release, see this [query:status=closed&resolution=fixed&milestone=0.7.1&type=defect report]. * For the list of all logged enhancements integrated in this release, see this [query:status=closed&resolution=fixed&milestone=0.7.1&type=enhancement report]. == Known Bugs == * For the list of known bugs still not fixed in this release, see this [report:3 report]. * For the list of all open tickets, see this [report:1 report].
