The record

Purpose: Leaflet is an open-source JavaScript library for building mobile-friendly interactive maps.
Lightweight: The site describes Leaflet as about 42 KB of JavaScript gzipped, plus 3.5 KB of CSS gzipped.
Map layers: Built-in layers include tile layers, WMS, markers, popups, vector shapes, image overlays, and GeoJSON.
Interactions: Map interactions include drag panning, wheel and pinch zoom, keyboard navigation, events, and draggable markers.
Customisation: Leaflet supports restyling popups and controls, custom layers and controls, custom projections, and extending classes.
Browser support: The site lists desktop browser support for Chrome, Firefox, Safari 5+, Opera 12+, IE 9–11, and Edge, and mobile support for iOS Safari 7+, mobile Chrome and Firefox, and IE10+ on Windows 8 devices.
Map data integrations: Leaflet can use OpenStreetMap tiles in its example and does not require a particular tile provider; tutorials cover WMS and TMS services.
Distribution: The stable release is available through unpkg, cdnjs, jsDelivr, direct downloads, and the npm package manager.
Release versions: The download page lists 1.9.4 as stable and 2.0.0-alpha.1 as prerelease, and cautions that the main development version may contain incompatible changes.
Security: The CDN example includes integrity hashes, which the page says are included for security when loading Leaflet from a CDN.
Support and learning: The site points users to tutorials, API documentation, a FAQ, GitHub issues, Stack Overflow, and GIS Stack Exchange for guidance and questions.
Notable scope limit: Leaflet says it focuses on making basic mapping features work well and suggests checking for a plugin when a feature is missing.
Contributor and origin: The project says it was originally created by Volodymyr Agafonkin and is now developed by a community of contributors.
