 <h1>Hush Dev Update #1</h1>
 
 <p>
+One exciting new bit of code for Hush is <a href="https://git.hush.is/hush/hush3/issues/283">Reduce memory usage of CBlockIndex</a>
+which is being ported from upstream Zcash. When it is ready it will reduce the memory needed to run a Hush full node by at least 1.6 GB
+and potentially much more. The more "indexes" that are enabled, the more memory savings. Since SilentDragon enables some indexes by default,
+which are not enabled in the CLI hushd, GUI wallet users will see even more memory savings. This means you can do more things with the same
+hardware without running out of memory or using much slower swap. This change will also help DragonX full nodes use less memory, but since
+RandomX block headers are much smaller, it will be on the order of tens of megabytes less RAM used.
