+## Nextclade CLI 1.2.3, Nextalign CLI 1.2.3 (2021-08-12)
+
+This release only affects docker images. There are no actual changes in Nextclade CLI, Nextalign CLI or Nextclade Web. They should behave the same as their previous versions.
+
+#### [Change] Add `ca-certificates` package into Debian docker images
+
+For better compatibility with workflows, this adds CA certificates into the Debian docker images. They are necessary for SSL/TLS to be working, in particular when fetching data.  
+
+These are the default images when you pull `nextstrain/nextclade` and `nextstrain/nextalign` without specifying a tag or specifying one of the `debian` tags. Issue `docker pull nextstrain/nextclade` to refresh the local image to the latest version.
