See the Construct 2 releases list. Releases in the last year cover approximately r99 to r137. The difference is truly night and day. Since r99 the big things we've added include: publishing mobile apps, publishing desktop apps, Windows 8 support, WebGL shader effects, containers, Function object, 9-patch object, WebSockets, Turret behavior, Pathfinding, more form controls, Z Order bar, advanced audio effects and positioned sounds, full-state save & load, persistent layouts, continuous preview, theme support, syntax highlighting and autocomplete in expressions, line-of-sight behavior, Geolocation, bookmark support, Sprite Font plugin, Timer behavior, regex support, and tonnes more that are smaller but nice to have (usability improvements, editor options like grids, snapping, showing collision polygons, etc) - plus hundreds of bug fixes and changes.
