Aptana Studio 3.4.2 installs PyDev 2.7.0.
How do I install PyDev 2.8.2?
I went to Help>Install New Software and added the site http://pydev.org/updates, checked 'Show only latest versions …' and 'Group items by category', pressed 'Next' and got the following error:
Cannot complete the install because of a conflicting dependency.

Next, I went to my AppData\Local\Aptana Studio 3\plugins directory & replaced all PyDev 2.7.0 files with the 2.8.2 set. When I opened Aptana I got a Could not open the editor: No editor descriptor for id org.python.pydev.editor.PythonEditor error.
I had heard that you can only do PyDev when installing Aptana, so I tried to extract the Aptana setup file Aptana_Studio_3_Setup_3.4.2.exe and replace those PyDev 2.7.0 files with the 2.8.2 set, but I couldn't find anything that looked familiar, so I left it be.
Aptana has it own pydev installed because of its internal dependencies, so it is not safe to update it and you have to wait Aptana team to release a new version of the software. If you want to be more flexible and update all the parts you need, just use plain Eclipse with all the plugins you need installed.(pydev, html, javascript, css and so on...)
There's an hack to do this: https://stackoverflow.com/a/25971061/398491
Basically you can install a beta version of Aptana in order to uninstall PyDev and then install the latest PyDev through the update site.
