+The **32-bit Windows binaries** formerly distributed by the Octave project are no longer supported.
+The download link has been removed from here but old installers are still available from the FTP mirrors.
+Patches for known issues are still welcome.
+An alternative source for 32-bit Windows binaries of Octave is
+[MSYS2](https://wiki.octave.org/Octave_for_Microsoft_Windows#GNU_Octave_in_MSYS2).
+
 All Windows binaries with corresponding source code can be downloaded from
 [https://ftpmirror.gnu.org/octave/windows/](https://ftpmirror.gnu.org/octave/windows/).
