IceFrog has released version 6.38b, one day after the release of version 6.38. This new version fix some exploits in version 6.38. Besides that nothing much has been changed. Another thing is that, IceFrog will provide downloads of the Dota Allstars 6.38b map file in zip file format, due to data integrity and browser incompatibility issues when downloading. All distributors are advised to provide the file in zip file format too.
