== Why should everybody (including you) test the release candidate? ==

In the past weeks the Lazarus team has stabilized the 1.6 fixes branch. The resulting 1.6RC1 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 1.4 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 1.6.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 1.6RC1.
- 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 (1.4.x), and use "Publish Project" from the project menu. This creates a clean copy of your project.

You can then open that copy in the RC1. 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

I read the change log of this RC1, congratulations for the Lazarus team, but i have a question, i not found any progress with GTK3 and QT5 widgetsets, exists any plan to support this?, GTK3 is in alpha state i now but, is not are plans respect to this for the future?.

missing the link to the checksums http://www.lazarus-ide.org/index.php?page=checksums#1_6_0RC1

Do Laz and fpc rpms support the --prefix option ?

[BBasile]

actually it seems that they're not (rpm -qi <name> on the previous one), how can I setup in my home ?

Well, I've found my first bug :-(

Trying to doubleClick on the form's event OnDestroy gives me an error : Unable to find method.
lclclasses.pp(26,10) : Error : unit classes not found

This seems to be the case as well when I doubleclick the OnClick-event of a button...

Is that a new install or an update?

If you updated without uninstall, then check that fpc source points to 3.0 (since your old install did probably have 2.6.4)

In any case, even if it points to 3.0 it there may be some caches still based on 2.6.4 .
Menu Tools "rescan fpc source direrctory"

It was an update, and I just did the rescan of the fpc directory as you suggested. And that helped 
Thank you!

Thank you very much. Some nice improvements.

When I install Internet packages - such as internet tools or LNet -
I get a warning: Recompiling sslsockets, checksum changed for OpenSSL
         and Fatal: Can not find sslsockets used by fphttpclient.

Can you help

         and Fatal: Can not find sslsockets used by fphttpclient.

That would be a problem in that package. Caused by circular unit references combined with some other feature, such as maybe inline.

Either:

1) Try to compile with inline disabled.

2) Open the package, and build it alone, repeat without making changes (1 or 2 repeats). The first build can be "build clean", but after that no "clean" anymore.
After that make sure not to change any settings, so it does not need any recompilation.
