IMPORTANT: Breaking changes

• The support for Emacs 24.3 has been dropped, Spacemacs needs at least Emacs 24.4 to work correctly.
• extensions are deprecated as announced in previous release, if you still have extensions directories you must rename them to local and move the contents of the extensions.el files to the packages.el files adding the keyword :location local to them in the package list. Refer to other layers for examples (for instance the python layer)
• <package>-excluded-packages variables are now deprecated as announced in previous release, you must now use the keyword :excluded t of the package list, see the vim-empty-lines layer for example.
• Key binding SPC : acting as M-x as been replaced by SPC SPC. If you want to revert to the old SPC : key binding set the new variable dotspacemacs-emacs-command-key to ":".
• Key binding SPC f e h is now SPC h SPC
• Key bindings to delete things are now more consistent and use the d key. We moved SPC w c and SPC w C to SPC w d and SPC w D.
• Refactor SPC w and SPC b regarding deletion to clean redundent actions and bring more consistency between the two prefixes (see Distribution layer changes section in change log for more information)
• SPC j prefix has been modified to include jump commands:
• avy commands are now behind the prefix SPC j for jump: - SPC j j to jump to a character in the buffer (works as an evil motion) - SPC j l to jump to a line with avy (works as an evil motion) - SPC j w to jump to a word in the current buffer (works as an evil motion)
• the following key bindings have been moved: - SPC j j to split a line has been moved to SPC j n - SPC j h and SPC j l have been moved to SPC j 0 and SPC j $ respectively. - SPC J to split a string or sexp has been moved to SPC j s
• All helm related key bindings under SPC h that are not about help have been moved to different key bindings:
• SPC h b for =helm-filetered-bookmarks~is now SPC f b
• SPC h l for helm-resume is now SPC r l
• SPC h L for helm-locate-library is now SPC f e l
• Git key bindings under SPC g have been reorganised to free up some keys and capitalize on Magit dispatch menu to keep things consistent (see git section in change log for more information)
• Spacemacs layouts scope has been changed, now SPC b b lists the buffers of the current layout, use SPC B b to list all the opened buffers.
• org-indent is now turned off by default
• Micro states are now called transient states, the macro spacemacs|define-micro-state is deprecated, it is replaced by the new hydra powered macro spacemacs|define-transient-state.
• Spacemacs layouts and workspaces transient states now exit when a layout or workspace is selected, use C-0 … C-9 to switch to a layout and keep the transient state open.
• Remove support for the value all for dotspacemacs-configuration-layers variable. To install all the packages supported by Spacemacs there is a new variable dotspacemacs-install-packages.
• Remove layer variable colors-enable-rainbow-identifiers in colors layer, You have to replace it by colors-colorize-identifiers 'all.
• The bépo layer has been replaced by the new layer keyboard-layout, see the README.org of the layer for more info.

Hot new features

• New option to lazy install layers based on auto-mode-alist (similar to Prelude lazy install of packages but for layers) via the variable dotspacemacs-enable-lazy-installation.

Dotfile changes

Changes for variable values and keywords

• Add new keyword :packages for the list of layers in variable dotspacemacs-configuration-layer, :packages allow to select or exclude packages from a layer.
• Add new keyword :enabled-for for the list of layers in variable dotspacemacs-configuration-layer, this keyword controls the effect of a layer on the other layers. For instance one can enable the auto-completion only for the python layer with the value (auto-completion :enabled-for python) Note that this keyword is the opposite of the existing keyword :disalbed-for. (thanks to TheBB)
• The value of dotspacemacs-editing-style can now be a list containing the keyword :variables (similar to dotspacemacs-configuration-layers) to define addtional variables to modify the behavior of the editing syle. This new keyword is useful for hybrid style which supports these variables:
• hybrid-mode-enable-evilified-state, if non nil then buffer are evilified,
• hybrid-mode-enable-hjkl-bindings, if non nil navigation on hjkl keys is enabled (for instance in helm buffers),
• hybrid-mode-default-state, the default state when opening a new buffer, by default it is normal.

• unused will lazy install only unused layers
• all will lazy install any layer that support lazy installation even the used layers
• nil disable the lazy installation feature

Default value is unused

• New variable dotspacemacs-frozen-packages. It is a list of packages, these packages cannot be updated or rollbacked.
• New variable dotspacemacs-install-packages which replaces the variable dotspacemacs-delete-orphan-packages. This new variable defines the behavior of Spacemacs for installed packages. Possible values are used-only, used-but-keep-unused and all.
• used-only installs only explicitly used packages and uninstall any

unused packages as well as their unused dependencies.

• used-but-keep-unused installs only the used packages but won't uninstall

them if they become unused.

• all installs all packages supported by Spacemacs and never uninstall

them. Default value is used-only.

• New variable dotspacemacs-emacs-command-key which replaces the variable dotspacemacs-command-key. This variable represents the key to press after the leader key to execute M-x. Default value is SPC.
• New variable dotspacemacs-folding-method to allow choosing between different code folding methods. Currently supported are evil and origami. Default value is evil. (thansk to ralesi)

• New variable dotspacemacs-retain-visual-mode-on-shift, If non nil > is remapped to >gv and < is remapped to <gv in visual mode, default value is nil (thanks to Stebalien)
• New variable dotspacemacs-visual-line-move-text, if non-nil, J and K move lines up and down when in visual mode. Default value is nil. (thanks to Stebalien)
• New variable dotspacemacs-helm-use-fuzzy. It controls fuzzy matching in helm. If set to always, force fuzzy matching in all non-asynchronous sources. If set to source, preserve individual source settings. Else, disable fuzzy matching in all sources. Default value is always (thanks to quicknir)
• New variable dotspacemacs-elpa-subdirectory. Can be nil or a form that evaluates to a package directory. For example, to use different package directories for different Emacs versions, set this to emacs-version (thanks to bmag, TheBB and emacs18)
