Martin_fr:

This release was built with FPC 3.0.4.
The previous release Lazarus 1.8.4 was built with FPC 3.0.4 as well.
Here is the list of fixes for Lazarus 2.0.x:

== Why should everybody (including you) test the release candidate? ==
In the past weeks the Lazarus team has stabilized the 2.0 fixes branch. The resulting 2.0RC2 is now stable enough to be used by any one for test purposes.
However many of the fixes and new features that where committed since the release of 1.8 required changes to the code of existing features too. While we have tested those ourself, there may still be problems that only occur with very specific configurations or one project in a million.
Yes, it may be that you are the only person with a project, that will not work in the new IDE. So if you do not test, we can not fix it.
Please do not wait for the final release, in order to test. It may be too late. Once the release is out we will have to be more selective
about which fixes can be merged for further 2.0.x releases. So it may be, that we can not merge the fix you require. And then you will miss out on all the new features.
== How to test ==
Download and install the 2.0 RC2.
- On Windows you can install as a 2ndary install, that will not affect
your current install:
http://wiki.lazarus.freepascal.org/Multiple_Lazarus#Installation_of_multiple_Lazarus
- On other platforms, if you install to a new location you need to use
--primary-config-path
In either case you should make backups. (including your primary config)
Open your project in the current Lazarus (1.8.x), and use "Publish2 Project" from the project menu. This creates a clean copy of your
project.
You can then open that copy in the RC2. Please test:
- If you can edit forms in the designer
- rename components / change properties in Object inspector / Add new
events
- Add components to form / Move components on form
- Frames, if you use them
- If you can navigate the source code (e.g. jump to implementation)
- Auto completion in source code
- Compile, debug and run
- Anything else you use in your daily work
mischi:
1) RC2 is not available for macOS as a download from http://sourceforge.net/projects/lazarus/files
2) I did a brief test of building the various variants of lazarus from https://svn.freepascal.org/svn/lazarus/branches/fixes_2_0/
All variants (carbon, cocoa, gtk2, Qt4 and win... cross-lcls) were built without problems. So far, I did not test running the variants.

It would be nice if users had another download, with -dTEST_WIN32_SEH:
https://sourceforge.net/projects/lazarus-snapshots/files/Window%2032/
lazarus-2.0.0RC2-?????-fpc-3.2.0-beta-?????-win32-seh.exe
Reason: AFAIK, there are at least two problems with Non-SEH exceptions:
1) catching os-exceptions in dll (propagate to host)
2) debugging with os-exceptions (app can't continue)
Especially, users coming from Delphi are very surprised about this.
JuhaManninen:
SEH is about FPC build, isn't it?
You can easily get Lazarus sources from SVN and build it yourself using the compiler you installed.

https://sourceforge.net/projects/lazarus-snapshots/ is a "semi official" channel.
That is files there are build and provided by members off the Lazarus team (currently just me), but they are snapshots, not part of the official release cycle.
Currently I put some builds with fpc from the 3.2 branch there. It is possible that fpc 3.2 will be released while Lazarus is releasing minor updates to Lazarus 2.0 (e.g. maybe when Lazarus 2.0.6 is due). In this case some Lazarus 2.0.x will likely be switched to use the new fpc 3.2. For that reason it is desirable that fpc from that branch is already tested.
For all I know this fpc will be released the same way, as the provided testbuilds. So whatever Lazarus will come with that fpc will not relay on seh for 32 bit.
Official Lazarus releases will only come with released versions of fpc, so to get any benefits of seh 32bit for production, the fpc team has to include this in their release.
Of course it would be nice to test all features, but there are a large amount of ways fpc can be build (with/without seh, with optimized rtl (different optimization levels), with debug rtl (-Criot and others), .... I cannot pre-build all of those.
Using fpcup-deluxe should provide means to get any fpc, with any build options you like.
