 Key Events
 ==========
 
-DAMON user-space tool evolvement.
-damo v2.0, 100 versions, 100 GitHub stars
-damo in Arch, Fedora, Debian, Kali, Ubuntu, Raspbian
+DAMON user-space tool, damo[2], got significant achievement in 2023.  'damo'
+was deployed via PyPI since 2021 August, and ArchLinux started packaing it
+since 2022 March[3].  In 2023, Fedora has been the second major Linux distro
+packaging the tool since May[4].  It has pacakaged for more distros, and as of
+this writing, ArchLinux, Debian, Devuan, Fedora, Kali Linux, Raspbian, and
+Ubuntu are[5] packaging the tool.  It also got it's 100th release[6] and 100th
+GitHub star in August.
+
+A few articles and papers introducing or exploring DAMON have published.  Two
+LWN articles[7,8] that briefly introducing DAMON's new feature and sharing
+detailed status/plan discussions on LSFMM, respectively, have published in
+March and May.  A blog post[9] from Hocus that briefly exploring DAMON as a way
+for reducing memory footprint on virtual machines together with free pages
+reporting feature has published in July.  In February[10], September[11], and
+Octover[12], papers exploring DAMON on tiered memory management have published
+by ArXiv and SOSP.  One more paper from Intel that improving DAMON for terabyte
+scale memory system has published by ArXiv in November[13].
+
+We also shared DAMON and its future plans with more people in multiple venues.
+We shared the development status and plans with other kernel developers at
+LSFMM[14] and Kernel Summit at LinuxPlumbers[15] in May and November,
+respectively, while also providing DAMON's high level usage and the user space
+tool at Open Source Summit North America[16] and Europe[17] in May and
+September, respectively.  Especially in LinuxPlumbers, we also had the second
+in-person DAMON community meetup[18], which doubled the number of attendee
+compared to the one we had in 2022.
+
+DAMON community has also committed[19] to test and share stable release
+candidate kernels since August.
+
+SK Hynix has released their second major version of Heterogeneous Memory
+Software Development Kit (HMSDK), which uses DAMON for their CXL-based tiered
+memory management, just a few days before this writing.  Maybe that's the first
+official product level tiered memory management usage of DAMON.

+A list of more detailed events in 2023 is available at the DAMON news page

+Key Features
+============
 
-Conferences.  OSSummit NA/EU, LSFMM, KSummit
+We started 2023 with Linux v6.2 that delivered DAMOS tried regions
+feature[20] that developed in 2022.
 
-Participate in stable rc kernel testing
+DAMOS filters[21] feature has developed and merged in the mainline by v6.3-rc1,
+which was released in March.  The feature has later expanded[22] for more use
+cases and merged in the mainline by v6.6-rc1, which was released in September.
 
-Key Features
-============
+Two more DAMON features for pseudo-moving average based reliable and speedy
+DAMON snapshot generation[23] and DAMOS-independent apply time interval[24]
+have developed and merged in the mainline by v6.7-rc1, which was reelased in
+November.
 
-v6.3, v6.6 DAMOS filter
-v6.7 Moving-average access rate
-v6.7 DAMOS apply interval
-Hopefully v6.8 DAMOS quota goals
+Finally, we developed user feedback-based DAMOS aggressiveness auto-tuning[25],
+which currently merged in the mm tree.  Hopefully it will be merged in the
+mainline by v6.8-rc1, which expected to be released in January.
 
 Development Statistics
