Release notes 2002 - 2008

  •  21 Jan 2008 04:00
Release Notes: Several changes has been made. Support for the partition table has been added. Legacy serial port routines have been fixed. Virtual terminal code has been separated from the EGA text mode driver. A Windows Sound System driver has been added. Support for FAT12/16 file systems is planned.

  •  15 Feb 2005 21:22
Release Notes: Memory paging and enhanced memory protection has been introduced. Several major bugs have been fixed. There are still many bugs, so the project maintains its pre-alpha status. The current pre-built image (jtm/jtm32.img) should boot up on VMware, with a Pico clone showing the introductory text.

Release Notes: Improvements were made in the windowing system. It is now possible to move windows. Windows are redrawn properly. Multiple windows can exist on top of each other. Threads can communicate via a simple message-based communication. The GUI now works as a special server to its clients (applications). The GUI API is still in development.

Release Notes: A memory corruption bug in the kernel file system service was fixed. This release contains a new rewritten TCP/IP stack which now responds to ICMP ping. 

  •  30 Apr 2003 20:50
Release Notes: Reliability related fixes have been made. There are also some new utilities. This release needs only one disk to work. LIBC now uses the QuickFit based allocation system, which has proven to be working quite well. This release has also passed a new stress test(runner.bin), such as repeated application launching for over 30,000 times.

Release Notes: In this version, FAT routines have been written from scratch, and the new FAT system has proven to be much stabler and faster. There are major fixes in the new kernel memory management system. Removable devices, such as floppy disk, are now hotswappable. Applications and kernel services now have larger stacks, this fixes many vague stack-related problems. The block cache has been disabled due to a forthcoming rewrite of it, therefore disk access is now much slower than before, but kernel panics are now prevented. Major changes have been made in the kernel to enable support for drives larger than 1 gigabyte (IDE CHS).

Release Notes: This release features a complete rewrite of the kernel memory management system, which fixes many of the performance- and reliability-related problems. A bug was located and fixed in the kernel process creator, which prevented programs like cp from launching properly.

Release Notes: Many file / cache system, LIBC and program fixes have been done. This release contains a new automated system installation. The OS file system is based on a special root device; all other devices show as subdirectories. Building system install disks was made a lot easier.

Release Notes: Disk access performance and stability have been improved. Various concurrency problems have been fixed. Changing between graphical and text video modes no longer causes text terminal data to be lost. Directories now work with the JTMFS file system. Changing between directories works.

Release Notes: Fixes were made to the file system and caching/buffering system. The disk cache now detects errors within itself, the kernel memory allocation system is now more reliable, and the read cache was disabled for all removable floppy disk drivers, fixing some problems. A "copyall" program was added, which is useful when operating system commands are missing and files have to be transfered between drives. A serial mouse driver was added, and fixes were made to the serial port driver, SLIP and TCP/IP, and OravaHTTPD. A VGA plasma effect and the GRAOS GUI were added.

Release Notes: A TCP/IP stack (uIP) has been added. JTMOS now answers to ICMP pings. Major fixes were made in the SLIP driver. A working and usable WWW server was added and tested. A telnet server has been introduced. Many interrupt related problems have been fixed. A snake game called 'Greedy Snake' has been ported to JTMOS. Split partitioning support for the first floppy disk drive was added, which allows a file system to be placed on the same disk as the system loader and system image.

Release Notes: Major bugs in the file system, FAT, serial port driver, floppy disk driver, and argc/argv were fixed. The serial device driver now emphasizes CPU performance. Added a device driver for Serial Line Internet Protocol (SLIP) based on the SLIP RFC, support for remote access via COM1 using a VT100 terminal, and other serial port related debugging features.

Release Notes: In this release, FAT has been upgraded from 16-bit to the 32-bit allocation system. Fixes have been made to LIBC file handling and the file system. Self-extracting archive creation is now possible (for Linux & JTMOS), 8-bit Sound Blaster is supported, and arguments now work for LIBC applications.
