# Release Notes

## Release 1.0.1475

This is the first preliminary release of the Coriolis 2 framework.

This release mainly ships the global router Knik and the detailed router Kite. Together they aim to replace the Alliance Nero router. Unlike Nero, Kite is based on an innovating routing modeling and ad-hoc algorithm. Although it is released under gpl license, the source code will be avalaible later.

Contents of this release:

1. A graphical user interface (viewer only).
2. The Knik global router.
3. The Kite detailed router.

Supported input/output formats:

- Alliance vst (netlist) & ap (physical) formats.
- Even if there are some references to the Cadence lefdef format, its support is not included because it depends on a library only available to Si2 affiliated members.

## Release 1.0.1963

Release 1963 is alpha. All the tools from Coriolis 1 have been ported into this release.

Contents of this release:

1. The Stratus netlist capture language (GenLib replacement).
2. The Mauka placer (still contains bugs).
3. A graphical user interface (viewer only).
4. The Knik global router.
5. The Kite detailed router.
6. Partially implemented python support for configuration files (alternative to xml).
7. A documentation (imcomplete/obsoleted in Hurricane‘s case).

## Release 1.0.2049
