RAWTHERAPEE 5.6 RELEASE NOTES

This is RawTherapee 5.6, released on 2019-04-20.

Start by reading the "Getting Started" article on RawPedia:

NEWS RELEVANT TO PHOTOGRAPHERS

RawTherapee supports most raw formats, including Pentax and Sony Pixel Shift, \ 
Canon Dual-Pixel, and those from 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.

In order to use RawTherapee efficiently you should know that:
- You can scroll all panels using the mouse scroll-wheel.
- You can right-click on a tool's name to automatically expand it while \ 
collapsing all others.
- To change slider values or drop-down list items with the mouse scroll-wheel, \ 
hold the Shift key. This is so that you can safely scroll the panels without \ 
accidentally changing a slider or other tool setting.
- All curves support the Shift and Ctrl keys while dragging a point. Shift+drag \ 
makes the point snap to a meaningful axis (top, bottom, diagonal, other), while \ 
Ctrl+drag makes your mouse movement super-fine for precise point positioning.
- There are many keyboard shortcuts which make working with RawTherapee much \ 
faster and give you greater control. Make sure you familiarize yourself with \ 
them on RawPedia's "Keyboard Shortcuts" page!

New features since 5.5:
- Pseudo-HiDPI support, for a smooth and sharp user interface regardless of \ 
screen size. Pseudo-HiDPI mode is disabled by default, enable it in Preferences \ 
> General > Appearance. Scaling in RawTherapee depends on font size, DPI \ 
and display scaling. While scaling has been tested to work well in Windows, \ 
Linux and macOS, there are some macOS display modes which are incompatible with \ 
it, specifically those modes suffixed by "(HiDPI)" in macOS Display \ 
settings. Some versions of macOS (10.14.*) seem to not list any modes, in which \ 
case the user must just give it a try.
- Ability to move tools to a new Favorites tab, \ 
http://rawpedia.rawtherapee.com/Favorites_Tab
- "Unclipped" processing profile, to make it easy to save an image \ 
while preserving data across the whole tonal range, \ 
http://rawpedia.rawtherapee.com/Unclipped
- User-adjustable tiles-per-thread settings in Preferences > Performance, for \ 
users who want to find optimal values for their system. The default value of 2 \ 
tiles-per-thread performs best overall.
- Hundreds of speed optimizations, bug fixes, and overall improvements.

NEWS RELEVANT TO PACKAGE MAINTAINERS

New since 5.5:
- Requires librsvg >=2.40.
- GTK+ versions 3.24.2 - 3.24.6 have an issue where combobox menu scroll-arrows \ 
are missing when the combobox list does not fit vertically on the screen. As a \ 
result, users would not be able to scroll in the following comboboxes: \ 
Processing Profiles, Film Simulation, and the camera and lens profiles in \ 
Profiled Lens Correction.

In general:
- To get the source code, either clone from git or use the tarball from \ 
http://rawtherapee.com/shared/source/ . Do not use the auto-generated GitHub \ 
release tarballs.
- Requires GTK+ version >=3.16, though >=3.22.24 is recommended.
- RawTherapee 5 requires GCC-4.9 or higher, or Clang.
- Do not use -ffast-math, it will not make RawTherapee faster but will introduce \ 
artifacts.
- Use -O3, it will make RawTherapee faster with no known side-effects.
- For stable releases use -DCACHE_NAME_SUFFIX=""
- For development builds and release-candidates use \ 
-DCACHE_NAME_SUFFIX="5-dev"
