 Changes in version 0.4.3.5 - 2020-05-15
-  COPY BLURB HERE.
+  Tor 0.4.3.5 is the first stable release in the 0.4.3.x series. This
+  series adds support for building without relay code enabled, and
+  implements functionality needed for OnionBalance with v3 onion
+  services. It includes significant refactoring of our configuration and
+  controller functionality, and fixes numerous smaller bugs and
+  performance issues.
+
+  Per our support policy, we support each stable release series for nine
+  months after its first stable release, or three months after the first
+  stable release of the next series: whichever is longer. This means
+  that 0.4.3.x will be supported until around February 2021--later, if
+  0.4.4.x is later than anticipated.
+
+  Note also that support for 0.4.1.x is about to end on May 20 of this
+  year; 0.4.2.x will be supported until September 15. We still plan to
+  continue supporting 0.3.5.x, our long-term stable series, until
+  Feb 2022.
 
   Below are the changes since 0.4.2.5. For a list of only the changes
   since 0.4.3.4-rc, see the ChangeLog file.
