While the Leaflet development team is busy with the 1.0 betas, there have been a few bugs affecting 0.7.3, important enough to spend some effort in porting a fix back. They are not much, though:
maxNativeZoomon tile layers and popup events
The detailed list of changes can be found in the changelog
The fact that it has been over a year and half since the last stable release should be a testament of the quality and stability of the Leaflet API. If you think that development of Leaflet 1.0 is taking a long time, remember that we want to keep the same level of quality for the final 1.0 release.
The 0.7.x releases will not implement new features. Stay tuned for more news on the 1.0 beta releases instead!
Developers using Leaflet 0.7.3 are advised to upgrade to 0.7.5 to prevent problems arising from modern browsers.
The release is also available through NPM, Bower, direct download, or through our CDN:
