I'm a bit confused about Eclipse release 3.8
It seems a bit like a ghost to me: no codename, no download site?
Where are all the packages, like "Eclipse for RCP and RAP Developers"?
Eclipse 3.8 and 4.2 were released concurrently as part of the Juno release, but the compilations for various developer types are only available based on version 4.2.
To use Eclipse 3.8, you will need to download the basic platform and install the plugins you need from Eclipse Marketplace or the Juno repository.
Surf to here and download the one labeled Eclipse SDK:
http://download.eclipse.org/eclipse/downloads/drops/R-3.8.2-201301310800/
Juno repository:
Official 'Eclipse Project 3.x' Stream Downloads page
http://download.eclipse.org/eclipse/downloads/eclipse3x.html
This has links to 3.8.1 release, and the 3.8 maintenance build.. If you want to link anywhere to 3.8, this is probably the best place.
Note that 3.8 is not a full 'packaged' release -- it's just the core. Features & plugins can be added from within the IDE, to replicate functionality of the Java EE/ PHP/ C++ etc packaged distributions.
3.8 is of particular interest to those (like myself) who are downgrading from 4.2 Juno due to the serious performance problems in that release. These seem to affect XML editors, PHP, switching, opening & closing editors -- turning the instant performance of previous Eclipse versions into endless 3-5 second waits.
Indigo 3.7 is the last 'packaged' release available. 3.8 may offer advantages in fixing several Indigo bugs & having Java 7 support.
A link to the recently released 3.8.2: http://archive.eclipse.org/eclipse/downloads/drops/R-3.8.2-201301310800/
None of the links in other answers seem to work anymore, but The Eclipse Project Updates Sites page at eclipse.org says it's http://download.eclipse.org/eclipse/updates/3.8 and that works for me and 3.8 has now been moved to the archives. I don't think updates are available anymore.
To install Java EE into the 3.8.1 download, this worked for me: https://stackoverflow.com/a/5028910/503025 Java EE is in the Juno upgrade site.
