Which version to take V.184.108.40.2060 beta and V.220.127.116.110 beta?
I asked same question sometimes back and I received the following answer from rick.lane
And a little bit more information: The 5.3.8.x versions are developed using an updated core and still have many items to be worked out. If you desire to test it out, I recommend that you use the portable version. Install versions, regardless of their version number, all use the same data file found at %appdata%\Maxthon 5 so installing a beta will also use that folder for it's data and could possibly add some data that one might not want added there. Each portable version has it's own data file so testing a beta version only affects the User Data folder of that particular portable version. With Maxthon 5 installed versions, one can only have one version installed at a time for this data folder reason, so it is much harder to go back a version if one finds that they have trouble with the installed version but the data folder has been changed to reflect entries made by the last installed version. I use only portable versions now so that I may have multiple versions on my hard drive at the same time and can choose which one I want to use. (I'm also a tester and can use the version of a questioner to attempt to help them out) In that way I can test a beta but be able to easily go back to a version that is more ready for prime time without worrying about the data file. Once you have at least one portable version installed and brought up to date, you simply copy the User Data folder from the last version into the folder for the new version and go from there. Sounds complicated but once you've done it, it's common sense from then on. Hope I didn't confuse you even more.> rick.lane
