+
+## `sudo`-less Containerlab
+
+I bet for many users prepending `clab` with `sudo` has become a pattern our finger muscles have remembered for years. Time to get rid of this habit.
+
+Thanks to @vista- work in #2408, Containerlab 0.63.0 ships one of its biggest quality of life features - the ability to run containerlab without `sudo`! Now, hold your horses, it doesn't mean you can run it as a regular user, the need for privileged access is still required to manage Linux things that we do. But now we do this in a more smart and user-friendly way.
+
+Read more about it [in the docs](../install.md#sudo-less-operation) and enjoy!
+
+Given the sheer blast radius this change brings, we are eager to hear your feedback. Ping us on Discord.
+
+## Gomplate is gone, so does the bloat
+
+For a couple of years Containerlab binary had a dependency on [gomplate](https://github.com/hairyhenderson/gomplate) - a tool that delivers advanced templating capabilities, but does it at a cost of 30MB of binary size. Since we never really used much of gomplate's features, we decided to remove it and add missing templating features based on the users feedback/request.
+
+Containerlab binary size went down from 80 to 40 MB.
+
+## Miscellaneous
+
+* fixed environment substitution so that unset variables are not substituted #2424
+* new command: `clab version check` to check if a newer version is available #2420 by @FloSch62
+* oepnconfig server enabled by default for SR Linux #2421
