| | 5 | This document contains a summary of changes made to HelenOS since release [wiki:ReleaseNotes/0.7.0 0.7.0]. |
| | 6 | |
| | 7 | == Special Notes for this Release == |
| | 8 | |
| | 9 | * 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. |

| | 11 | == Features Introduced in This Release == |
| | 12 | |
| | 13 | === General === |
| | 14 | |
| | 15 | * This is the last release which uses the Bazaar version control system (VCS). Future releases will use Git. |
| | 16 | * The system can again be built by clang for amd64 |
| | 17 | |
| | 18 | === Kernel === |
| | 19 | |
| | 20 | * Basic support for capabilities |
| | 21 | * 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. |
| | 22 | * IRQ structures are now managed using capabilities. It is no longer possible to unregister someone else's IRQ. |
| | 23 | * The limit of 64 IPC phones has been removed and is now virtually infinite. |
| | 24 | * The kernel is now using the resizable hash table which has been already used in uspace since 2012. |
| | 25 | |
| | 26 | === Services and Drivers === |
| | 27 | |
| | 28 | * The naming service was converted to use the async framework |
| | 29 | * CUDA driver was converted to the Device Driver Framework |
| | 30 | * The interrupt controller drivers were converted to using the Device Driver Framework |
| | 31 | * User can now unload an idle driver using `devctl unload-drv` |
| | 32 | * Framebuffer now gets mapped only when actually used |
| | 33 | |
| | 34 | === File Systems === |
| | 35 | |
| | 36 | * All file system operations are relative to a specified node, client-side root |
| | 37 | * Mountpoints are no longer stored in the filesystem servers, but in VFS |
| | 38 | * Inbox mechanism for passing files from parent to a new child |
| | 39 | * Client-side I/O cursors (file positions) |
| | 40 | * Overhaul of the [wiki:FilesystemAPITutorial client interface]; all APIs begin with the vfs_ prefix and can be used after including vfs/vfs.h |
| | 41 | * Removal of some POSIX-ish headers and definitions |
| | 42 | * File system probing |
| | 43 | * Volume label support |
| | 44 | |
| | 45 | === Networking === |
| | 46 | |
| | 47 | * Lots of networking fixes in TCP, DNS and HTTP protocols |
| | 48 | * TCP unit tests |
| | 49 | |
| | 50 | === Applications === |
| | 51 | |
| | 52 | * The `pkg` utility was added which allows installing packages from [http://ci.helenos.org/latest/ ci.helenos.org] into a running instance of HelenOS |
| | 53 | |
| | 54 | === Libraries === |
| | 55 | |
| | 56 | * Effort towards greater C11 compliance and a cleaner cut between HelenOS-specific, C11 and POSIX code |
| | 57 | * io/table module to print tabular output (used by devctl, inet). |
