What's in store for Leaflet in future? What's new in the next release? A talk by the creator of the library.

1. Future of Vladimir Agafonkin 09.09.14
5. next version: 1.0
6. since the first release 3.5 years ago the biggest update
7. sometime 
 next month hopefully
8. born against ! all odds
9. no way you could do that
10. You’re wasting time
11. build an OPENLAYERS wrapper
12. born as a protest against bloat, clutter and complexity
13. top priorities: simplicity performance
14. 1.0
15. evolution not revolution
16. animations & usability
17. fractional zoom: map.setZoom(12.67)
18. ballistic panning
19. better tile loading (less flickering)
20. better panning inertia
21. fixed gaps during zoom on Safari for Mac
22. smoother zoom on iOS Safari
23. popup fade out animation
24. vectors 2.0
25. Use SVG & Canvas on the same map
26. put vectors in custom panes
27. huge SVG layers performance boost: adding ~3x faster, takes ~2.5 less memory
28. huge Canvas layers performance boost: partial redraws, faster mouse events
29. Canvas layers now retina-enabled
30. solved all problems with MultiPolygon & MultiPolyline: no longer inherited from FeatureGroup
31. Polyline & Polygon Centroids
32. TileLayer
33. TileLayer split into GridLayer & TileLayer
34. GridLayer is the new TileLayer.Canvas
35. var tiles = L.tileLayer.canvas(); ! tiles.drawTile = function(canvas, tile, zoom) { var ctx = canvas.getContext('2d'); … // draw something }; old way
36. var tiles = L.gridLayer(); ! tiles.createTile = function(coords) { var tile = document.createElement('canvas'), ctx = canvas.getContext('2d'); … // do anything }; new way
37. Projections
38. No hardcoded projection hacks, all centralized in CRS
39. CRS defines everything: how tiles wrap, what are the bounds, distance measure, etc.
40. Proj4Leaflet FTW Thanks, Per!
41. Layers
42. all layers now inherited from Layer class less code, more consistency, good for plugins
43. Custom Pane Management
44. map.createPane(‘foobar’); ! L.tileLayer(url, {pane: ‘foobar’});
45. other performance improvements
46. LatLng construction 8x faster
47. faster Layer construction
48. huge FeatureGroup performance boost due to better event propagation mechanism
49. much better memory footprint for DOM & Leaflet events
50. obj.off(event, listener) 2x faster
51. …and many other bugfixes and improvements
52. best of all? it got smaller!
53. Uncompressed: 208.75 KB (-6798 bytes) Compressed: 116.91 KB (-5696 bytes) Gzipped: 31.71 KB (-1062 bytes) stable vs master
54. so why does it take so long?
57. Leaflet 0.7.3 is so good
58. Mapbox GL JS
60. incredibly complex technology and tons of code
61. to experiment, blow minds and create amazing map interactions
62. Leaflet will remain the go-to mapping library: dead simple, easy to use, works on all platforms, 
 tons of plugins, huge community, everyone knows it
63. Leaflet & Mapbox GL benefit from each other
65. thank you
