It has always bothered me that I can’t find earlier versions of Mule product. Someone asked me the same question today. So I took myself to task to figure out the bottom of this thing. I think I may have found the holy grail, so to speak.
In this case, my colleague wants to download anypoint studio version 5.4.3, instead of the current 6.1 release. So I followed the standard studio download link https://www.mulesoft.com/platform/studio, before I clicked the final download, I extracted the URL, which reveals this https://mule-studio.s3.amazonaws.com/6.1.1-U1/AnypointStudio-for-win-64bit-6.1.1-201609131828.zip
Choosing a Global Software Development Partner to Accelerate Your Digital Strategy
To be successful and outpace the competition, you need a software development partner that excels in exactly the type of digital projects you are now faced with accelerating, and in the most cost effective and optimized way possible.
I then just cut the first part and place it in the browser https://mule-studio.s3.amazonaws.com/.
Voila! The secret source showed up. The XML content shows the pattern, I found the 5.4.3 link is https://mule-studio.s3.amazonaws.com/5.4.3-NOV15-U3/AnypointStudio-for-win-64bit-5.4.3-201603290717.zip. I actually saw older versions all the way up to 5.0.x in this file.
Anyway, you get the idea, if you need to download the previous version or older version of Mule product, you can use the same trick. Have fun!
haha, 5/22/17 update, i found another link for ESB https://repository-master.mulesoft.org/nexus/content/repositories/releases/org/mule/distributions/mule-standalone/
Ironically i went there to look for 3.6.2. That’s missing from there though.
