-RAWTHERAPEE 5.2 RELEASE NOTES
------------------------------
-This is a development version of RawTherapee. We update the code almost daily. Every few months, once enough changes have accumulated and the code is stabilized, we make a new official release. Every code change between these releases is known as a "development" version, and this is one of them.
+RAWTHERAPEE 5.3-rc1 RELEASE NOTES
+---------------------------------
+This is RawTherapee 5.3 Release Candidate 1 stable, released on 2017-09-25.
 
 RawTherapee provides you with a selection of powerful tools with which you can practice the art of developing raw photos. Be sure to read RawPedia to understand how each tool works so that you may make the most of it.

 A great place to start is the "Getting Started" article. Click on "Main page" in the top-left corner when you have finished reading that article to see all other articles.
 
-While we only commit tested and relatively stable code and so the development versions should be fairly stable, you should be aware that:
-- Development versions only had limited testing, so there may be bugs unknown to us.
-- You should report these bugs so that they get fixed for the next stable release. See
-  www.rawpedia.rawtherapee.com/How_to_write_useful_bug_reports
-- The way new tools work in the development versions is likely to change as we tweak and tune them, so your processing profiles may produce different results when used in a future stable version.
-- Bugs present in the stable versions get fixed in the development versions, and make it into the next stable version when we make a new official release. That means that in some ways the development versions can be "more stable" than the latest stable release. At the same time, new features may introduce new bugs. This is a trade-off you should be aware of.

-RawTherapee supports most raw formats, including some unusual ones like those from cameras using Foveon and X-Trans sensors. If you're wondering whether it supports your camera's raw format, first download RawTherapee and try for yourself. If a raw format is not supported it will either not open, or the preview in the Editor tab will appear black, white, or have a strong color cast - usually magenta. In that case, read the "Adding Support for New Raw Formats" RawPedia article.

 News Relevant to Developers
 ---------------------------
 - Announce and discuss your plans in GitHub before starting work.
 - Keep branches small so that completed and working features can be merged into the "dev" branch often, and so that they can be abandoned if they head in the wrong direction.
 - Use C++11.
-- Code must be run through astyle.
