The development cadence is classified as zombie due to the lack of activity over the last 16 months. The most recent release occurred on March 11, 2026, and there have been no subsequent updates or evidence of ongoing maintenance. The previous major update in early 2025 introduced significant UI and functional changes, but the project appears to have stalled since then.

The Analyst's Read

Key takeaways for JassScore - Jass ScoreKeeper

Where is it heading?

The utility market for card games is consolidating around tools that offer automated assessment and tournament management. JassScore's current maintenance-mode posture leaves it vulnerable to rivals that offer higher-fidelity analytics, so the PM must pivot to stability to avoid losing the core user base.

  • Data loss regressions in the latest version drive negative sentiment, which compounds the existing frustration regarding basic player management.
  • Recent updates focus on minor UI fixes, suggesting the team is currently in maintenance mode rather than aggressive feature expansion.
