Changelog

May 6, 2025

Moved suggestion report to pop out in its own window (similarly to bug report)
Fixed errors in the API returning incorrect CS/AR values
Increased harshness of similarity curve but softened weights of the similarity algorithm

Further reduced the overhead memory usage of the similarity algorithm (from 5 to ~3 seconds)
Added mod filtering for suggestions

Implemented mod combinations for searching and suggestions
Added bug report form and info pop up on start
Added scaling for extremely high CS and AR to more correctly weigh maps like precision and AR11
Reduced the overhead and memory usage of the similarity calculations (from 15 to ~5 seconds)
Further added scaling to other attributes associated with the similarity algorithm

Upgraded to Next 15 and React 19
Added artist and song metadata
Added report button with feedback for alternative maps
Added beatmap card and status
Implemented rate limiter (2 requests every 10 seconds for similarity search, 1 report every 30 seconds)
Replaced database implementation with osu!api calls using ossapi (allowed for more metadata options)
Increased the weight of AR and slightly changed weights of other parameters in the similarity algorithm

Added various attributes and statistics to each map (BPM, CS, AR, OD, HP, etc.)
Expanded search to 20 beatmaps
Added info box for updates and clarifications
Added social bar with Discord, Twitter, and osu! links
Added database helper for retrieving some metadata
Changed the similarity scoring system to a power-based scale, where 100 is the maximum
Updated database from January 2025 to May 2025 osu! dump
Increased the weight of BPM and CS in the similarity algorithm

Created backend API for similarity algorithm
Added clickable links for each beatmap ID
Increased weight of speed/object ratio for more accurate stream vs burst map distinction
