-## [2.0.0-rc.3] - 2018-09-27
-
-- Switch export method
-
-## [2.0.0-rc.2] - 2018-09-26
-
-- Added a changelog.md
-- Reverted `a.click()` to use dispatch with a try-catch ([#465], [#382])
-- Made third argument to an object where you have to pass `{ autoBom: true }`
-  - boolean are depricated but still works
-
-## [2.0.0-rc.1] - 2018-09-26
-
-- saveAs don't return anything
-  - The object that dispatched `writestart progress write writeend` are gone
-  - detecting such features was never possible and nobody seems to use it.
-- Removed the demo folder
-- Removed date/version from top of the file
-- Dosen't crash in web workers ([#449])
-- Support saving urls ([#260] with workarounds for cross origin)
-- Uses babel universal module pattern (UMD) to export the package
-- Provides source map now as well.
-- use a[download] before msSaveAs ([#193], [#294])
-- removed dist from .gitignore (npm uses it if it don't find a .npmignore)
-- autoBom is now reversed so you have to tell when you want to use autoBom ([#432])
-- `a.click()` since there are new and depricated event constructors that works differently ([#382])
-- opens up a new popup (tab) directly for the fallback method since the FileReader is async
-- removed the explicitly MSIE [1-9] check
-- Uses new anchor link for each save (might solve multiple download problems)
