Prepare for 1.37.1 release and fix CI.

In the cross compilation case, we need to resolve our
dependencies on libc twice, once for the build machine and once for the
target machine. This includes pthreads, -libc, and android-spawn.

 # Changelog
 All notable changes to this project will be documented in this file.
 
-## ??? - Unreleased
+## 1.37.1 - 2024-12-05
+- Fix meson cross compilation
+- Update timeout documentation for networking APIs: timeouts raise errors and do not return nil.
+- Add `janet_addtimeout_nil(double sec);` to the C API.
+- Change string hashing.
+- Fix string equality bug.
+- Add `assertf`
 - Change how JANET_PROFILE is loaded to allow more easily customizing the environment.
 - Add `*repl-prompt*` dynamic binding to allow customizing the built in repl.
 - Add multiple path support in the `JANET_PATH` environment variables. This lets
   user more easily import modules from many directories.
+- Add `nth` and `only-tags` PEG specials to select from sub-captures while
+  dropping the rest.
 
 ## 1.36.0 - 2024-09-07
 - Improve error messages in `bundle/add*` functions.
