Almost four years since the last major release the release of the visual operating system (VISual OPerating SYStem), developed since 1997 and different from Windows and Unix. The system's code was developed from scratch and is distributed in source text under the GPLv2 license. The bootable Live image is 21 MB.
The graphical subsystem, which forms the user interface, is integrated directly into the OS kernel, while console mode operation is also supported. The file systems offered in read/write mode include FAT32, while Ext2/3/4 is additionally supported in read-only mode. Visopsys features preemptive multitasking, multithreading, a network stack, dynamic linking, asynchronous input/output support, and virtual memory. A standard set of applications and standard C libraries is prepared. The kernel operates in 32-bit protected mode and is designed in a massively monolithic style (everything is compiled, with no module support). Executable files are formatted in the standard ELF format. There is built-in support for JPG, BMP, and ICO images.
In :
- A TCP stack and DHCP client have been added. The network subsystem is enabled by default. Separate sections with network applications have been added to the 'Programs' and 'Administration' sections. Programs for traffic sniffing (Packet Sniffer) and standard utilities such as netstat, telnet, wget, and host have been added.
- Support for Unicode (UTF-8) has been added.
- A package manager called 'Software' and infrastructure for creating, loading, and installing packages have been implemented. An online package catalog has been introduced.
- The appearance has been updated. The window shell has been transitioned to operate as a regular user-space application (the kernel-level operation option has been retained).
- A mouse driver has been added for guest systems running under VMware.
- Libraries for working with HTTP, XML, and HTML have been added.
- Initial support for C++ runtime has been added.
- New Libc calls have been added, including getaddrinfo(), getwchar(), mblen(), mbslen(), putwchar(), wcscmp(), wcscpy(), wcslen(), wcstombs().
- Initial support for multithreading based on the POSIX Threads library (pthreads) has been added.
- Support for unnamed pipes for inter-process data exchange has been added.
- The core includes built-in support for SHA1 and SHA256 hashing algorithms (previously MD5 was offered), as well as the addition of the sha1sum and sha256sum utilities.
