   was often useful, it also broke some existing workflows, and there wasn't a good way to opt out of it. And there isn't really a good way for us to add
   a way to opt out of it. And you can easily get similar behavior by adding `.git/` to your global fdignore file.
     See #1457.
+- Add `-f` \ `--filter <command>` argument that allows you to filter results based on the output of a command, as requested in #400.
 
 ## Bugfixes
 
 - Respect NO_COLOR environment variable with `--list-details` option. (#1455)
 - Fix bug that would cause hidden files to be included despite gitignore rules
   if search path is "." (#1461, BurntSushi/ripgrep#2711).
+- aarch64 builds now use 64k page sizes with jemalloc. This fixes issues on some systems, such as ARM Macs that
+  have a larger system page size than the system that the binary was built on. (#1547)
+- Address [CVE-2024-24576](https://blog.rust-lang.org/2024/04/09/cve-2024-24576.html), by increasing minimum rust version.
