+## [10.0.0](https://github.com/mermaid-js/mermaid/releases/tag/v10.0.0)
+
+### Mermaid is ESM only!
+
+We've dropped CJS support. So, you will have to update your import scripts as follows.
+
+```html
+<script type="module">
+  import mermaid from 'https://cdn.jsdelivr.net/npm/mermaid@10/dist/mermaid.esm.min.mjs';
+  mermaid.initialize({ startOnLoad: true });
+</script>
+```
+
+You can keep using v9 by adding the `@9` in the CDN URL.
+
+```diff
+- <script src="https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.js"></script>
++ <script src="https://cdn.jsdelivr.net/npm/mermaid@9/dist/mermaid.js"></script>
+```
+
+### mermaid.render is async and doesn't accept callbacks
+
+```js
+// < v10
+mermaid.render('id', 'graph TD;\nA-->B', (svg, bindFunctions) => {
+  element.innerHTML = svg;
+  if (bindFunctions) {
+    bindFunctions(element);
+  }
+});
+
+// Shorter syntax
+if (bindFunctions) {
+  bindFunctions(element);
+}
+// can be replaced with the `?.` shorthand
+bindFunctions?.(element);
+
+// >= v10 with async/await
+const { svg, bindFunctions } = await mermaid.render('id', 'graph TD;\nA-->B');
+element.innerHTML = svg;
+bindFunctions?.(element);
+
+// >= v10 with promise.then
+mermaid.render('id', 'graph TD;A-->B').then(({ svg, bindFunctions }) => {
+  element.innerHTML = svg;
+  bindFunctions?.(element);
+});
+```
+
+### mermaid.parse is async and ParseError is removed
+
+```js
+// < v10
+mermaid.parse(text, parseError);
+
+//>= v10
+await mermaid.parse(text).catch(parseError);
+// or
+try {
+  await mermaid.parse(text);
+} catch (err) {
+  parseError(err);
+}
+```
+
+### Init deprecated and InitThrowsErrors removed
+
+The config passed to `init` was not being used eariler.
+It will now be used.
+The `init` function is deprecated and will be removed in the next major release.
+init currently works as a wrapper to `initialize` and `run`.
+
+```js
+// < v10
+mermaid.init(config, selector, cb);
+
+//>= v10
+mermaid.initialize(config);
+mermaid.run({
+  querySelector: selector,
+  postRenderCallback: cb,
+  suppressErrors: true,

+
+//>= v10
+mermaid.initialize(config);
+mermaid.run({
+  querySelector: selector,
+  postRenderCallback: cb,
+  suppressErrors: false,
+});
+```
+
+// TODO: Populate changelog pre v10
 
 - Config has a lot of changes
 - globalReset resets to `defaultConfig` instead of current config. Use `reset` instead.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+- Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at security@mermaid.live
+.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.0, available at
+https://www.contributor-covenant.org/version/2/0/code_of_conduct.html.
+
+Community Impact Guidelines were inspired by [Mozilla's code of conduct
