 ## Release a new version

-#### 1. Bump the versions by running `./make-release.sh`
+#### 1. Create a 'Cut release $VERSION' issue

-The `./make-release.sh` script has git commands to pull main but to be sure you can run the following git commands to have a fresh `main` locally.
+It will be used to document changelog discussions and release testing.
+
+https://github.com/KittyCAD/modeling-app/issues/new
+
+#### 2. Push a new tag
+
+Create a new tag and push it to the repo. The `semantic-release.sh` script will automatically bump the minor part, which we use the most. For instance going from `v0.27.0` to `v0.28.0`.

 ```
-git branch -D main
-git checkout main
-git pull origin
-./make-release.sh
-# Copy within the back ticks and paste the stdout of the change log
-git push --set-upstream origin <branch name created from ./make-release.sh>
+VERSION=$(./scripts/semantic-release.sh)
+git tag $VERSION
+git push origin --tags
 ```

-That will create the branch with the updated json files for you:
- run `./make-release.sh` or `./make-release.sh patch` for a patch update;
- run `./make-release.sh minor` for minor; or
- run `./make-release.sh major` for major.
+This will trigger the `build-apps` workflow, set the version, build & sign the apps, and generate release files as well as updater-test artifacts.

-After it runs you should just need the push the branch and open a PR.
+The workflow should be listed right away [in this list](https://github.com/KittyCAD/modeling-app/actions/workflows/build-apps.yml?query=event%3Apush)).

-#### 2. Create a Cut Release PR
-
-When you open the PR copy the change log from the output of the `./make-release.sh` script into the description of the PR.
-
-**Important:** Pull request title needs to be prefixed with `Cut release v` to build in release mode and a few other things to test in the best context possible, the intent would be for instance to have `Cut release v1.2.3` for the `v1.2.3` release candidate.
-
-The PR may then serve as a place to discuss the human-readable changelog and extra QA. The `make-release.sh` tool suggests a changelog for you too to be used as PR description, just make sure to delete lines that are not user facing.

-The other `build-publish-apps` output in Cut Release PRs is `updater-test-{platform}`. As we don't have a way to test this fully automatically, we have a semi-automated process. For macOS, Windows, and Linux, download the corresponding updater-test artifact file, install the app, run it, expect an updater prompt to a dummy v0.255.255, install it and check that the app comes back at that version.

 The only difference with these builds is that they point to a different update location on the release bucket, with this dummy v0.255.255 always available. This helps ensuring that the version we release will be able to update to the next one available.

+layout: manual
+---
+
+`KCL` allows splitting code up into multiple files.  Each file is somewhat
+isolated from other files as a separate module.
+
+When you define a function, you can use `export` before it to make it available
+to other modules.
+
+```
+// util.kcl
+export fn increment(x) {
+  return x + 1
+}
+```
+
+Other files in the project can now import functions that have been exported.
+This makes them available to use in another file.
+
+```
+// main.kcl
+import increment from "util.kcl"
+
+answer = increment(41)
+```
+
+Imported files _must_ be in the same project so that units are uniform across
+modules. This means that it must be in the same directory.
+
+Import statements must be at the top-level of a file. It is not allowed to have
+an `import` statement inside a function or in the body of an if-else.
+
+Multiple functions can be exported in a file.
+
+```
+// util.kcl
+export fn increment(x) {
+  return x + 1
+}
+
+export fn decrement(x) {
+  return x - 1
+}
+```
+
+When importing, you can import multiple functions at once.
+
+```
+import increment, decrement from "util.kcl"
+```
+
+Imported symbols can be renamed for convenience or to avoid name collisions.
+
+```
+import increment as inc, decrement as dec from "util.kcl"
+```
