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

In the past weeks the Lazarus team has stabilized the 1.8 fixes branch. The resulting 1.8RC2 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 1.6 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 1.8.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 1.8 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 (1.6.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 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

I saw a Linux Lazarus V1.9.0  ..... is that a bogus release, or what ?

The About says :

Version #: 1.9.0
Date 2017-05-03
FPC Version: 3.0.2
SVN Revision: 54803
arm-linux-gtk2

[Martin_fr]

1.9.0 is currently trunk. That is the development version with daily (untested) changes.

Versions with an odd digit in 2nd or 3rd are between releases.

1.9.0 => trunk (before branching 1.8, trunk was 1.7)
1.6.5 => development on the 1.6 branch

[thijsvandien]

Just a minor remark not directly related to the RC: both topic titles have 'candidate' misspelt.

[Martin_fr]

Fixed, form auto-complete explains the second.

Thank you Lazarus Team.
