 Summary
 =======
 
 2023 was yet another year of active and healthy DAMON development.  DAMON has
-hopefully more stabilized but continued active development.  The growth of the
-DAMON user-space tool, damo, was especially impressive.
-
-DAMON has explored and used by more people and products.  DAMON user-space
-tool, damo[2], got its 100th GitHub star, and deployed by seven major Linux
-distros' packaging systems.  Four papers and three articles that explore and/or
-introduce DAMON have published by peope other than the maintainer of DAMON.  A
-product that managing tiered memory using DAMON has officially released.
-
-Substantial amount of development was also continued.  Four major DAMON kernel
-side features have developed.  Signficant amount of new features for damo has
-added.  Damo has also released its second major version (v2.0).
