Hot new feature

Extensive use of lazy loading of packages and other tricks to reduce Spacemacs startup time. In most cases you should see a noticable improvement in load time and smoothness in startup. We also added the time spent to load your personal dotspacemacs/user-config so you can quickly spot if it is a bottleneck (thanks to Sylvain Benner, Ben Leggett, and bmag)
Added support for native line numbers in Emacs 26+ (thanks to bmag)
Improved themes support. Support are now handled like regular packages. The list of themes now supports :location keyword like in package lists. More information in the Themes section of the documentation.
Added environment-variable caching. At startup, if the cache does not exist, Spacemacs loads environment variables using exec-path-from-shell and writes the cache to be used on next startup. Please read carefully the new documentation section Environment variables and PATH in DOCUMENTATION.org (thanks to Sylvain Benner, Codruț Constantin Gușoi, and Paolo G. Giarrusso)
Improved support of custom settings file. All custom settings are now encapsulated in a function called dotspacemacs/emacs-custom-settings in the dotfile if the user does not specify a custom location for the custom settings file by modifying the variable custom-file. This allows Spacemacs to correctly loads custom settings at the end of the loading process, fixing unwanted overriden custom settings by layers. See section Custom variables in DOCUMENTATION.org.
Introduction of spacemacs-purpose layer in charge of handling Emacs windows assignation for actions opening new buffers. This layer brings more consistency to windows creation by giving them a purpose (i.e. edit, help, etc…). See emacs-purpose repository for more info. (thanks to bmag)
New distribution spacemacs-docker used to build the official docker image for the Spacemacs container (thanks to Eugene Yaremenko)
Added support for ripgrep. To enable it add rg to dotspacemacs-search-tools. ripgrep key bindings are under SPC s r prefix. (thanks to Aron Griffis)
Simplify declaration of company backends, see the section Add auto-completion in a layer of the README.org file of the auto-completion layer.
Added experimental support for the emacs portable dumper; see EXPERIMENTAL.org. This allows for instant Spacemacs startup time with pre-loaded heavy packages like Org and Helm (thanks to Sylvain Benner, Compro Prasad and Keith Simmons)

Breaking Changes

Major

Support for Emacs 24 has been dropped, the minimal Emacs version is now 25.1.

Core

Change loading order of layers init functions. Previously the pre-init, init and post-init function were called in a row for each package. Now all pre-init functions are called for all packages, then all init functions of all packages are called, finally all post-init functions of all packages are called. It might require some updates of your private layers.
All custom settings are now encapsulated in a function called dotspacemacs/emacs-custom-settings which is managed by Spacemacs and written to your dotfile. This allows Spacemacs to control when those settings are applied. While it should not break your custom settings you should check that they are all applied correctly once you reboot Emacs. Also you may have to clean up your dotfile if some custom settings are still present in your dotfile outside of the function dotspacemacs/emacs-custom-settings.
Company backends declaration has been revamped to be less verbose and easier to use. For more info see the section Add auto-completion in a layer of the README.org file of the auto-completion layer, also you can read commit message of commit 74fdbb6.
The function add-flycheck-hook has been renamed to enable-flycheck.
The property :powerline-scale of variable dotspacemacs-default-font has been removed and replaced by the property :separator-scale used in the new dotfile variable dotspacemacs-mode-line-theme.

Layers

- SPC b m now opens the *Messages* buffer. The old SPC b m to kill other buffers has been moved to SPC b C-d. Killing other buffers using a regular expression is now under SPC b C-D.

- Changed SPC j j from evil-avy-goto-char to evil-avy-goto-char-timer, and removed default binding for evil-avy-goto-char-2 (thanks to duianto and Sylvain Benner)
