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.

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.

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.
