-> Elm 0.19 was [recently released][elm-0.19]. It makes major, breaking changes
-> to the compiler's interface with packages like this one. It is likely the
-> next release of Elm Language Support will break compatibility with Elm 0.18.
->

-> Control to ignore updates to this package until you are ready to upgrade.
-> In Sublime Text, choose **Preferences > Package Settings > Package Control >
-> Settings – User**, then add this setting to your
-> **Package Control.sublime-settings** file:
-> 
-> ```json
-> {
->   "auto_upgrade_ignore": [
->     "Elm Language Support"
->   ],
-> }
-> ```
-> 
-> #### Upgrading to Elm 0.19
-> 
-> A pre-release version of this package with experimental support for Elm 0.19
-> is available. If you're using Elm 0.19 already, we'd value your feedback!
-> 
-> **Warning:** This new version does not support Elm 0.18!
-> 
-> To upgrade, configure Package Control to install pre-release versions of this
-> package. In Sublime Text, choose **Preferences > Package Settings > Package
-> Control > Settings – User**, then add this setting to your
-> **Package Control.sublime-settings** file:
-> 
-> ```json
-> {
->   "install_prereleases":
->   [
->     "Elm Language support"
->   ],
-> }
-> ```
-> 
-> Then use the **Package Control: Upgrade Package** command in the Command

+New in Elm Language Support 1.0.0-beta.1 (August 22, 2018)
+==========================================================
+
+This prerelease version provides experimental support for the just-released
+Elm 0.19, and BREAKS COMPATIBILITY with Elm 0.18 and earlier.
+
+Read about Elm 0.19 here:
+<https://github.com/elm/compiler/blob/master/upgrade-docs/0.19.md>
+
+Please report issues on GitHub:
+<https://github.com/elm-community/SublimeElmLanguageSupport/issues>
+
+
+What's New
+----------
+
+The following features have been removed, as they depend on elm-oracle, which
+has not yet been updated to support Elm 0.19:
+
+ - Removed: Display type signatures for symbols under the cursor in the status
+   bar.
+ - Removed: Elm type info panel (alt/option-up/down keyboard shortcuts).
+ - Removed: Autocompletion of Elm symbols available in the current module.
+
+The build system was rewritten to support the new output format of the Elm 0.19
+compiler. The following features have yet to be reimplemented:
+
+ - Removed: Support for enabling/disabling build warnings (Elm 0.19 has removed
+   compiler warnings for now).
+ - Removed: Ability to build your whole project to an output file from within
+   Sublime Text. For now, the build system builds only the current module (and
+   everything it imports), which is sufficient for getting quick compiler
+   feedback on the code you're working on. But to actually run your all, you'll
+   need some other way of running a build of your whole project for now.
+
+And there is one new feature that will come in handy for those of you juggling
+multiple Elm versions on your machine:
+
+ - New: `elm_binary` setting that lets you override the path and filename to the
+   Elm binary file (`elm`) that Sublime Text uses to build your code.
