Version 3

Highlights

  • Glicko2 ratings, with graphical charts

  • Old championships are gone, old seasons has been renamed to championships

    People got confused by the overlapping functionality, old championships were an attempt to compute national-wide rankings: the new Glicko2-based ratings are much better at that

  • Augmented players information to fit international tourneys requirements, clubs may be marked as federations

  • Easier interfaces to insert and modify

  • Easier way to upload players portraits and clubs logos

  • Hopefully easier installation

  • Better infrastructure to accomodate database migrations

  • Simpler way to detect potential duplicated players

  • Most entities carry a GUID that make it possible to reliably match them when imported from a different SoL instance

  • Players merges are tracked and distribuited to other SoL instances

Dark ages

Scarry was a Delphi 5 application I wrote years ago, with the equivalent goal. It started as a "quick and dirty" solution to the problem, and Delphi was quite good at that. It has served us with good enough reliability for years, but since programming in that environment really bored me to death, there's no way I could be convinced to enhance it further.

SoL is a complete reimplementation, restarting from scratch: it uses exclusively free software components, so that I won't be embaraced to publish the whole source code.
