2011/4/14 - New Release

[Chris Broadfoot (Google Employee)]

Hi all,

We recently pushed a new version of the Maps API. The major change in this release is Polylines and Polygons are now rendered in Canvas. This provides a significant speedup when adding many polys to a map. One known issue is that polygons are hidden when strokeOpacity is zero. As a workaround, set your strokeOpacity to something non-zero (say, 1e-32).

Polyline/Polygon stroke/fill colors now need to be specified in full hex notation (i.e. '#FF0000', rather than 'red' or '#F00'). This has long been the documented way of providing a color, but previously any CSS color worked.

We also recently made changes to our terms of service. Please read this blog post for a summary of the changes:

The changelog for this release is copied below. See the full changelog here:

As always, discussion is open on the developer forum:

Resolved issues:

  * Fixed regression: Marker icon and shadow no longer transparent on IE6

  * Fixed: Markers no longer flicker on zoom

  * Fixed: Rendering of polygons across tile boundaries near the north/south poles

Noticeable changes:

  * Polylines and Polygons now rendered in Canvas where possible.

  * LatLngs for events on polylines and polygon borders now snap to the nearest point on the line.

Thanks,

Chris
