So, here's a bulleted list of items that were notable to me:
- Under Linux, the buttons appear in the correct order (!). So "OK" appears on the bottom, right hand corner of a dialog, according to GNOME standards.
- The Install tool is much nicer, making it a lot easier to find the right plugin quickly, such as Subversive, which is pretty much a required plugin these days.
- Sadly, the Subversive SVN Connectors repository isn't enabled by default, so you need to add a couple extra update sites
- VE is still installable under Galileo, though it continues to be the 1.4 version. Linux support continues to be present, but weak. (Installation instructions)
- Webtools has long had a "Download and Install..." button for Tomcat 6 in the Servers view, but it still points at an out of date release (6.0.14) and failed to function on system. Nevertheless, it's easy enough to download Tomcat 6.0.20, extract it and place it under the control of Eclipse for deploying, testing, and debugging web/JSP/servlet projects.
- A large number of servers are still supported, and the "Download additional server adapters" feature continues to exist, but the adapters need to be updated (the Glassfish adapters require an obsolete plugin, and the Jetty plugin fails to install).
- CDT appears to work better than the last time I took a serious look at it. Completions seem to work better and more refactorings and source transformations appear to be available which should make working with headers and implementation files easier. I'm not sure it's enough to keep me out of Emacs, but it's getting closer.
- It looks like TPTP is going into "Maintenance mode," and as such, has seen some improvement with respect to reliability. Under Linux, with Sun's Java 6 (update 13), code profiling works "out of the box." In the past, it used to require fiddling with Agents or switching to older releases of Java, due to the tooling API change in Java from JVMDI to JVMTI.
- Mylyn continues to be solid and has a workable plugin installer (for third party support for additional task trackers).
So, the new release is an improvement. Some third party items need to be updated (particularly the additional Webtools adapters). If those tools are required, it would be best to wait some time before upgrading.
I'm still waiting for an improved welcome page with connections to the Eclipse community (similar to what I've seen in Visual Studio's start view).
