+### v2.30.1 (28-Aug-2021)
+
+- [HTML] Changed user avatars to render using higher resolution images. (Thanks [@Chris Helder](https://github.com/TheDude53))
+- Fixed an issue where `has:file` message filter was not recognized. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- Fixed an issue where a unix timestamp marker with an invalid offset crashed the export process.
+
+### v2.30 (08-Aug-2021)
+
+- [HTML] Added special casing for Spotify track embeds to render them directly using an embedded player.
+- [HTML] Added special casing for plain image embeds to render them like image attachments.
+- [HTML] Added tooltip text for unix timestamp markers which shows the full date represented by the timestamp, regardless of configured date format. 
+- [HTML] Updated the fallback text shown when the referenced message could not be loaded to make it more explicit.
+- [HTML] Updated styling of quoted text in markdown to more closely resemble how it looks in Discord.
+- [HTML] Fixed an issue where some file formats were not correctly recognized as image or video attachments, which affected how they were rendered.
+- [HTML] Fixed an issue where formatting inside named links (e.g. `[**Bold link**](https://example.com)`) was not being parsed.
+- [HTML] Fixed an issue where inline embed fields were missing horizontal spacing between columns.
+- [HTML] Fixed other minor styling issues.
+
+### v2.29 (19-Jul-2021)
+
+- Added support for message filtering, which is accessible as an additional export parameter in the GUI and as the `--filter` option in the CLI. Message filters use a special syntax similar to Discord's search query syntax to allow specifying which messages should be included in the export. For example, you can limit the export to only include messages that contain image attachments (`has:image`) or messages from a certain user (`from:Tyrrrz`) or messages containing certain words (`hello world`), etc. You can also combine filters together (`hi mentions:Tyrrrz`, `from:Tyrrrz | from:96-LB`, `(mentions:Tyrrrz | from:Tyrrrz) has:image`) or negate them (`-has:link`). More thorough documentation coming soon. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- Added support for rendering mentions of voice channels, in addition to text channels.
+- Added support for rendering unix timestamp markers. Currently, style markers are ignored and timestamps are always rendered with the format configured in settings (or provided via `--date-format` option).
+- Updated in-app instructions for obtaining a user token. (Thanks [@Yudi](https://github.com/Yudi) and [@virtuallyvlad](https://github.com/virtuallyvlad))
+- [HTML] Improved visual appearance of the reference symbol (Г-shaped line in replies) to make it more closely resemble Discord's styling.
+- [HTML] Added more specific fallback text used when rendering referenced messages that contain no text content but have attachments or embeds.
+- [HTML] Fixed an issue where a broken embed author icon occupied visual space, ruining the embed layout. (Thanks [@Cliff J.](https://github.com/CliffJameston))
+- [GUI] Improved handling for fatal errors that may occur when attempting to export a channel. These errors are now displayed in a popup, allowing the user to try again instead of having the application crash completely.
+- [CLI] Fixed an issue where an attempt to export a channel resulted in `NotSupportedException` when the default encoding was set to `UTF8`.
+- [CLI] Fixed an issue where providing an incorrectly formatted partition limit via `-p|--partition` option resulted in a non-descriptive and unhelpful error.
+- Improved "Requested resource does not exist" error message by including the ID of the requested resource.

 - [HTML] Updated Twemoji URLs to use SVG image variants for better rendering quality.

 ### v2.21 (18-Jul-2020)

- Added a new option that enables self-contained exports for all output formats. You can turn it on in the export setup dialog in GUI or using the `--media` option in CLI. When using this, the application will additionally download any media content directly referenced from the exported file instead of linking back to Discord CDN. The files which are downloaded include: guild icons, user avatars, attachments, embedded images, reaction emojis. Note that only files which are actually referenced by the export are downloaded, which means that, for example, user avatars will not be downloaded when using plain text export format. This option is not meant to enable complete offline viewing for HTML exports, but rather to make it easier to archive media content that may eventually get deleted from Discord servers. Also keep in mind that this option may make the export drastically slower and the total file size larger.

 - Changed "discordapp.com" to "discord.com" where applicable as Discord is migrating to a new domain. CDN will remain on "cdn.discordapp.com" for the foreseeable future.

 Note that all existing and current HTML exports will likely not render accurately because Discord enabled CORS for their font resources, which prevents them from loading locally. Please refer to [issue #322](https://github.com/Tyrrrz/DiscordChatExporter/issues/322) for discussion on this topic.

 - [HTML] Changed default color of the embed color pill to match the theme.
- [HTML] Changed emoji parser to be less greedy. As a result it should match fewer character sequences that look like emojis but really aren't, but on the other hand it might miss some actual emojis. This means that some standard emojis (i.e. not custom server emojis) may not look like in Discord. This is a compromise I'm willing to take because detecting emojis in text is really hard to get right and not worth it at all.

-## Building the project locally
-
-Prerequisites:
-
- [.NET 5.0 SDK](https://dotnet.microsoft.com/download/dotnet/5.0)
- [.NET 3.1 SDK](https://dotnet.microsoft.com/download/dotnet/3.1) (temporarily as the app still targets .NET 3.1, but requires .NET 5.0 to build)
- _(Optional)_ C#/.NET IDE, such as [JetBrains Rider](https://www.jetbrains.com/rider), [VS Code](https://code.visualstudio.com/docs/languages/csharp), or [Visual Studio](https://visualstudio.microsoft.com).
-
-To build the entire solution run the following command in the root of the repository:
-
-```sh
-> dotnet build
-```
-
-This will generate runtime artifacts for each project:
-
-```plaintext
-./DiscordChatExporter.Gui/bin/[Debug|Release]/[runtime]/*
-./DiscordChatExporter.Cli/bin/[Debug|Release]/[runtime]/*
-```
-
-You can also build and run a specific project directly.
-To do that, navigate to its directory and use `dotnet run`:
-
-```sh
-> cd DiscordChatExporter.Gui
-> dotnet run
-```

+# DiscordChatExporter Tests
+
+This test suite runs against a real Discord server, specifically created to exercise different behaviors required by the test scenarios.
+In order to run these tests locally, you need to join the test server and configure your authentication token.
+
+1. Join the server: https://discord.gg/eRV8Vap5bm
+2. Locate your Discord authentication token
+3. Specify your token using a file or an environment variable:
+    - **Using a file**: put your token in a new `DiscordToken.secret` file created in this directory
+    - **Using an environment variable**: set `DISCORD_TOKEN` variable to your token
+4. Run the tests: `dotnet test`
+
+> If you're submitting a pull request, you don't _have_ to run the tests locally -- they are executed automatically by CI.
+Running them locally can still sometimes be useful for debugging purposes though.
+ 
+> If you want to have a new test case or a scenario added, please let me know in your pull request.
+Currently, it's not possible to add them by yourself.
