What's new in Lemma.
A running log of every significant update to the platform – features, improvements, and fixes.
v0.12New
SCI breakdown, wallet improvements, adaptive assessments v2
- SCI breakdown bars now visible in Skill Passport – each component (Practice, Proof, Reliability, Freshness) shows its score and contribution to the total.
- LemmaCoins wallet upgraded with granular transaction types: teaching_earned, session_hold, late_cancel_compensation, and more replace generic debit/credit entries.
- Assessment adaptive difficulty engine v2 ships with tighter calibration – difficulty adjusts every 3 questions instead of every 5.
- Proof history on skill detail page now shows exact SCI delta per event, not rounded values.
- Passport shareable link can now be previewed without logging in – employer verification works fully unauthenticated.
v0.11New
Session recording (with consent), skill passport link, team dashboard beta
- Session recording is now available with explicit double-consent from both participants before recording begins. Recordings are stored encrypted in R2.
- Skill passport now generates a permanent, shareable URL at /passport/:userId – suitable for embedding in resumes and LinkedIn.
- Team dashboard beta gives organization admins a view of all member SCI scores, session activity, and skill coverage gaps.
- Session reminder notifications added – push notification sent 5 minutes before scheduled start time.
- LiveKit video quality improvements reduce connection setup time by 40% in low-bandwidth environments.
v0.10Improvement
Smart matching v2, mobile session UI, GitHub proof integration
- Smart matching engine upgraded from 8 to 12 signals: adds learning pace compatibility, language proficiency depth, and prior session outcome history.
- Session UI is now fully responsive – mobile users can join and conduct sessions without UX degradation.
- GitHub proof integration lets users attach specific commits, PRs, or repositories as external evidence to their skill passport.
- Session no-show detection improved – system now tracks join events and auto-completes sessions based on confirmed attendance rather than manual input.
- Matching discovery algorithm now uses a teacher quality index updated nightly to surface higher-reliability teachers first.
v0.9New
Public beta launch – core peer sessions, basic passport, SCI v1
- Public beta opens to the first cohort of practitioners – peer session booking, live video via LiveKit, and post-session evidence generation are live.
- Skill Passport v1 ships with Claimed, Novice, Competent, Proficient, Expert, and Authority tiers driven by accumulated SCI evidence.
- SCI v1 formula goes live: Practice (25 pts), Proof (40 pts), Reliability (20 pts), Freshness (15 pts) – full methodology published at getlemma.io/product/sci.
- LemmaCoins (LC) economy launches with free monthly grants for all users and earnings from teaching sessions.
- Developer API (beta) available for early partner teams – assess and verify endpoints with API key authentication.
