+This file provides documentation on how to build the *ELPA* library in **version ELPA-2021.11.001.rc1**.
 With release of **version ELPA-2017.05.001** the build process has been significantly simplified,
 which makes it easier to install the *ELPA* library.
 
-The release ELPA 2018.11.001 was the last release, where the legacy API has been
-enabled by default (and can be disabled at build time).
-With the release ELPA 2019.11.001, the legacy API has been deprecated and the support has been closed.
+As anounced, with the the release 2021.11.001.rc the **legacy interface has been removed**.
 
-The release of ELPA 2021.05.002 does change the API and ABI compared to the release 2019.11.001, since
-the legacy API has been dropped.
+The release of ELPA 2021.11.001.rc1 does change the API and ABI compared to the release 2020.05.002.
