 *** Hot new features:
-- Whole new package list used in the file =packages.el= of a layer. Packages
-  can now be a list with keyword properties, the currently supported
-  properties are =:location=, =:step= and =:excluded=. =extensions.el= files
-  and =<layer>-excluded-packages= variables are now optional and will be
-  deprecated in the next version 0.105.0.
-- New =distribution= concept, you can now choose between two distribution
-  layers: =spacemacs= and =spacemacs-base=. =spacemacs-base= contains only
-  a minimal set of packages. Use =spacemacs= distribution to get the full
-  Spacemacs experience.
-- Add support for =Quelpa= which allows to use =Melpa= to install packages
-  directly from source (i.e. one can now install a package from a Github
-  repository).
+- Enhanced layer package lists which merge old extension lists and package
+  lists. Keywords can be associated with packages. The supported keywords
+  are =:location=, =:step= and =:excluded=.
+ =extensions.el= files and =<layer>-excluded-packages= variables are now
+  optional and will be deprecated in the next version 0.105.0.
+- New =distribution= concept: you can now choose between two distributions:
+ =spacemacs= or =spacemacs-base=. =spacemacs-base= contains only
+  a minimal set of packages whereas =spacemacs= is the full Spacemacs
+  experience. Set the distribution with =dotspacemacs-distribution= variable.
+- Add support for =Quelpa= which allows to use =Melpa= recipes to install
+  packages directly from source (i.e. one can now install a package directly
+  from a Github repository).
 - New editing style: =hybrid=. This style is similar to Vim style except that
   all Emacs key bindings are available in hybrid (insert) state instead of Vim
   key bindings. Also in this state, the buffers are evilified like in Vim style.
 - The default theme of Spacemacs is now =spacemacs-dark=. The Spacemacs themes
-  (=spacemacs-dark= and =spacemacs-light=) becomes the official themes of
-  Spacemacs, official screenshots should be taken with one of these themes.

+  (=spacemacs-dark= and =spacemacs-light=) become the official themes of
+  Spacemacs (thanks to nashamri)
 - Add support for dotdirectory =~/.spacemacs.d= which behaves like the Emacs
   dotdirectory (i.e. =~/.spacemacs.d/init.el= is evaluated instead of
  =~/.spacemacs= if the former exists and the latter does not) (thanks to
   justbur)
-- Guide-key is replaced by =which-key= which provides a enhanced and better
-  live key bindings browsing experience.
-  (thanks to justbur)
-- Whole new API to manage the =powerline= mode-line. It is now possible to
-  easily define segments and arrange them (thanks to TheBB)
-- New web gallery to browse themes in =themes-megapack=,
-  URL: [[http://themegallery.robdor.com][theme gallery]] (thanks to robmerrell)
