NEW: 07.05.2025

We are pleased to announce the availability of Topoly 1.1.0. This version introduces new functionality and
fixes several incompatibilities with the latest versions of the dependencies: NumPy 2.x and Matplotlib 3.10. It is also the
first version supported on Python 3.13.

Since version 1.0.4 Topoly is also available for **Mx Apple Silicon Mac** and **Windows 7/8/10/11**.
Look at the `Topoly requirements <https://topoly.cent.uw.edu.pl/installation.html>`_ for details.

What you can do with Topoly?
----------------------------------

* Calculate knot/link invariants:

  * Polynomials: Alexander, Jones, Conway, HOMFLY, Yamada, Kauffman, BLM/Ho,
  * Brackets: Kauffman, APS,
  * Other: writhe, Gaussian linking number.

* Find minimal surface of a loop.
* Simplify polymer structure preserving its topology.
* Generate random polygon structures: walks, loops, lassos, handcuffs.
* Generate knot map (like in KnotProt).
* Calculate sum (U) and product (#) of knots.
* Visualize structures.
