-about: Coordinate steps to publish a new release
-title: 'Checklist and coordination for v0.0.0 major/minor/patch release'
-labels: release
-assignees: '@publiclab/is-maintainers'
---
-
-This template guides us through the steps of creating a new release, based on conversation and testing in [#1692](https://github.com/publiclab/image-sequencer/issues/1692).
-
-Discuss with @publiclab/is-maintainers if anything is ambiguous!
-
-<!-- NOTE: Change v0.0.0 to the appropriate release version -->
-
-* [x] open an issue using the "release" template with this checklist with title `Checklist and coordination for v0.0.0 major/minor/patch release` (see [semantic versioning](https://docs.npmjs.com/about-semantic-versioning/))
-* [ ] create a release [project](https://github.com/publiclab/image-sequencer/projects) from [this template](https://github.com/publiclab/image-sequencer/projects/5). You can copy a project from its menu.
-* [ ] compile release notes below from corresponding [release project](https://github.com/publiclab/image-sequencer/projects).
-* [ ] open a pull request with updated version numbers
-    * [ ] update version number in `examples/sw.js` (ex #1734) and `package.json` (ex #1695)
-    * [ ] update version number in `package.json`
-    * [ ] run `npm install` to update `package-lock.json` (from recent node version - 16 at time of writing, in GitPod should work)
-* [ ] finalize and merge to `main` branch (freeze merges to `main` branch until next step)
-
-Now, move to `stable` branch:
-
-* [ ] force push from `main` to `stable`
-* [ ] then in `stable` branch, compile `/dist/` files with `grunt build`
-* [ ] add `/dist/` files with `git add -f /dist/*` and commit them to `stable` branch
-* [ ] run `npm publish`
-
-Draft a release:
-
-* [ ] [create a release on GitHub](https://github.com/publiclab/image-sequencer/releases) and use features description + release notes from below
-* [ ] tag version number branch (i.e. `v0.0.0`) based on `stable` or choose `stable`
-* [ ] publish tagged branch to `npm` with `npm publish` (logging in first as necessary)
-* [ ] publish to live Github pages [demo](https://sequencer.publiclab.org) (with [bash script](https://github.com/publiclab/image-sequencer/pull/1703) from `/scripts/update-demo`) (from within GitPod works well)
-* [ ] move anything necessary to next release project, i.e. <!-- Update this link -->https://github.com/publiclab/image-sequencer/projects/[insert project number]
-* [ ] close this issue!
-
-Noting we're now in this process in https://github.com/publiclab/image-sequencer/issues/1751 for `v3.7.0`.

-## Scripts
-The following shell scripts are present in the `scripts/` directory.
-
- `update-gh-pages`: This script can be used to update the `gh-pages` branch of this repo or a fork.
- This script is not meant to be used directly as it runs in the current working directory.
- If you run it on your primary local clone, it can **delete** the local changes. This script is made to be used in a github action
- or in a temporary directory via another script, such as `update-demo`.
-
-  Arguments:
-  1. Repo(to use as upstream) url in the form username/repo (default: publiclab/image-sequencer) NOTE: Github only
-  2. Branch to pull from eg: main or stable (default: stable)
-  3. CNAME URL (default: none)
-  4. Set the fourth argument to anything to bypass the warning. You will have to set this argument if you want to run this script in another script without needing
-  user interaction, such as in a github action.
-
- `update-demo`: A safe, interactive script that can be used to update the `gh-pages` branch of any image-sequencer fork.
- This script is safe to use directly because it separately clones the repo in a temporary directory.
-
-  Arguments: None since it is a an *interactive* script, ie it asks the user for input.

-This module is used to sharpen the pixels of the image using a 3x3 convolution filter.
-#### Usage
-
-```js
-  sequencer.loadImage('PATH')
-           .addSteps('sharpen',options)
-           .run()
