 Sometimes, things might go wrong, and you end up with a half-flashed drive that is unusable by your operating systems, and common graphical tools might even refuse to get it back to a normal state.
 To solve these kinds of problems, we've collected [a list of fail-proof methods](https://github.com/balena-io/etcher/blob/master/docs/USER-DOCUMENTATION.md#recovering-broken-drives) to completely erase your drive in major operating systems.
 
-## I receive "No polkit authentication agent found" error in GNU/Linux
+## I receive ”No polkit authentication agent found” error in GNU/Linux
 
 Etcher requires an available [polkit authentication agent](https://wiki.archlinux.org/index.php/Polkit#Authentication_agents) in your system in order to show a secure password prompt dialog to perform elevation. Make sure you have one installed for the desktop environment of your choice.
 
 ## May I run Etcher in older macOS versions?
 
-Etcher GUI is based on the [Electron](http://electron.atom.io/) framework, [which only supports macOS 10.10 and newer versions](https://github.com/electron/electron/blob/master/docs/tutorial/support.md#supported-platforms).

-## Can I use the Flash With Etcher button on my site?

+Type
+----
+
+Must be one of the following:
+
+- `feat`: A new feature.
+- `fix`: A bug fix.
+- `minifix`: A minimal fix that doesn't warrant an entry in the CHANGELOG.
+- `docs`: Documentation only changes.
+- `style`: Changes that do not affect the meaning of the code (white-space,
+formatting, missing semi-colons, JSDoc annotations, comments, etc).
+- `refactor`: A code change that neither fixes a bug nor adds a feature.
+- `perf`: A code change that improves performance.
+- `test`: Adding missing tests.
+- `chore`: Changes to the build process or auxiliary tools and libraries.
+- `upgrade`: A version upgrade of a project dependency.
+
+Scope
+-----
+
+The scope is required for types that make sense, such as `feat`, `fix`,
+`test`, etc. Certain commit types, such as `chore` might not have a clearly
+defined scope, in which case its better to omit it.
+

+### `Change-Type: <type>`
+
+This tag is used to determine the change type that a commit introduces. The
+following types are supported:
+
+- `major`
+- `minor`
+- `patch`
+
+This tag can be omitted for commits that don't change the application from the
+user's point of view, such as for refactoring commits.
+
+Examples:
+
+```
+Change-Type: major
+Change-Type: minor
+Change-Type: patch
+```
+
+See the [Semantic Versioning][semver] specification for a more detailed
+explanation of the meaning of these types.
+
+### `Changelog-Entry: <message>`
+
+This tag is used to describe the changes introduced by the commit in a more
+human style that would fit the `CHANGELOG.md` better.
+
+If the commit type is either `fix` or `feat`, the commit will take part in the
+CHANGELOG. If this tag is not defined, then the commit subject will be used
+instead.
+
+You explicitly can use this tag to make a commit whose type is not `fix` nor
+`feat` appear in the `CHANGELOG.md`.
+
+Since whatever your write here will be shown *as it is* in the `CHANGELOG.md`,
+take some time to write a decent entry. Consider the following guidelines:
+
+- Use the imperative, present tense.
+- Capitalize the first letter.
+
+There is no fixed length limit for the contents of this tag, but always strive
+to make as short as possible without compromising its quality.
+
+Examples:
+
+```
+Changelog-Entry: Fix EPERM errors when flashing to a GPT drive.
+```
+
+Complete examples
+-----------------
+
+```
+fix(GUI): ignore extensions before the first non-compressed extension
+
+Currently, we extract all the extensions from an image path and report back
+that the image is invalid if *any* of the extensions is not valid , however
+this can cause trouble with images including information between dots that are
+not strictly extensions, for example:
+
+    elementaryos-0.3.2-stable-i386.20151209.iso
+
+Etcher will consider `20151209` to be an invalid extension and therefore
+will prevent such image from being selected at all.
+
+As a way to allow these corner cases but still make use of our enforced check
+controls, the validation routine now only consider extensions starting from the
+first non compressed extension.
+
+Change-Type: patch
+Changelog-Entry: Don't interpret image file name information between dots as image extensions.
+Fixes: https://github.com/balena-io/etcher/issues/492
+```
+
+***
+
+```
+upgrade: etcher-image-write to v5.0.2
+
+This version contains a fix to an `EPERM` issue happening to some Windows user,
+triggered by the `write` system call during the first ~5% of a flash given that
+the operating system still thinks the drive has a file system.
+
+Change-Type: patch
+Changelog-Entry: Upgrade `etcher-image-write` to v5.0.2.
+Link: https://github.com/balena-io-modules/etcher-image-write/blob/master/CHANGELOG.md#502---2016-06-27
+Fixes: https://github.com/balena-io/etcher/issues/531
+```
+
+***
+
+```
+feat(GUI): implement update notifier functionality
+
+Auto-update functionality is not ready for usage. As a workaround to
+prevent users staying with older versions, we now check for updates at
+startup, and if the user is not running the latest version, we present a
+modal informing the user of the availiblity of a new version, and
+provide a call to action to open the Etcher website in his web browser.
+
+Extra features:
+
+- The user can skip the update, and tell the program to delay the
+notification for 7 days.
+
+Misc changes:
+
+- Center modal with flexbox, to allow more flexibility on the modal height.
+interacting with the S3 server.
+- Implement `ManifestBindService`, which now serves as a backend for the
+`manifest-bind` directive to allow the directive's functionality to be
+re-used by other services.
+- Namespace checkbox styles that are specific to the settings page.
+
+Change-Type: minor
+Changelog-Entry: Check for updates and show a modal prompting the user to download the latest version.

 Release Types
 -------------
 
-Etcher supports **pre-release** and **final** release types as does Github. Each is
-published to Github releases.
-The release version is generated automatically from the commit messasges.
+Etcher supports **production** and **snapshot** release types. Each is
+published to a different S3 bucket, and production release types are code
+signed, while snapshot release types aren't and include a short git commit-hash
+as a build number. For example, `1.0.0-beta.19` is a production release type,
+while `1.0.0-beta.19+531ab82` is a snapshot release type.
+
+In terms of comparison: `1.0.0-beta.19` (production) < `1.0.0-beta.19+531ab82`
+(snapshot) < `1.0.0-rc.1` (production) < `1.0.0-rc.1+7fde24a` (snapshot) <
+`1.0.0` (production) < `1.0.0+2201e5f` (snapshot). Keep in mind that if you're
+running a production release type, you'll only be prompted to update to
+production release types, and if you're running a snapshot release type, you'll
+only be prompted to update to other snapshot release types.
+
+The build system creates (and publishes) snapshot release types by default, but
+you can build a specific release type by setting the `RELEASE_TYPE` make
+variable.  For example:
+
+```sh
+make <target> RELEASE_TYPE=snapshot
+make <target> RELEASE_TYPE=production
+```
+
+We can control the version range a specific Etcher version will consider when
+showing the update notification dialog by tweaking the `updates.semverRange`
+property of `package.json`.
+
+Update Channels
+---------------
+
+Etcher has a setting to include the unstable update channel. If this option is
+set, Etcher will consider both stable and unstable versions when showing the
+update notifier dialog. Unstable versions are the ones that contain a `beta`
+pre-release tag. For example:
+
+- Production unstable version: `1.4.0-beta.1`
+- Snapshot unstable version: `1.4.0-beta.1+7fde24a`
+- Production stable version: `1.4.0`
+- Snapshot stable version: `1.4.0+7fde24a`

-# i18n
-
-## How it was done
-
-Using the open-source lib [i18next](https://www.i18next.com/).
-
-## How to add your own language
-
-1. Go to `lib/gui/app/i18n` and add a file named `xx.ts` (use the codes mentioned
-   in [the link](https://www.science.co.il/language/Locale-codes.php), and we support styles as `fr`, `de`, `es-ES`
-   and `pt-BR`)
-   .
-2. Copy the content from an existing translation and start to translate.
-3. Once done, go to `lib/gui/app/i18n.ts` and add a line of `import xx_translation from './i18n/xx'` after the
-   already-added imports and add `xx: xx_translation` in the `resources` section of `i18next.init()` function.
-4. Now go to `lib/shared/catalina-sudo/` and copy the `sudo-askpass.osascript-en.js`, change it to
-   be `sudo-askpass.osascript-xx.js` and edit
-   the `'balenaEtcher needs privileged access in order to flash disks.\n\nType your password to allow this.'` line and
-   those `Ok`s and `Cancel`s to your own language.
-5. If, your language has several variations when they are used in several countries/regions, such as `zh-CN` and `zh-TW`
-   , or `pt-BR` and `pt-PT`, edit
-   the `langParser()` in the `lib/gui/app/i18n.ts` file to meet your need.
-6. Make a commit, and then a pull request on GitHub.
