+### v2.27 (24-Apr-2021)
+
+- Added partitioning by file size. You can now use values such as `10mb` to indicate a size-based cut off point, in addition to values like `10` to indicate a number of messages. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- [CLI] Improved formatting and progress reporting.
+- [CLI] Changed `export` command so that it can accept multiple channel IDs passed to `-c|--channel` option. This makes it possible to export multiple channels at once while benefiting from parallelization.
+- [JSON] Added `color` field to message author. This is a hex string that represents user's color, inherited from their roles. (Thanks [@rtm516](https://github.com/rtm516))
+- [JSON] Added `categoryId` field to the root. This represents the ID of the category channel that the currently exported channel belongs to. (Thanks [@rtm516](https://github.com/rtm516))
+- [JSON] Fixed an issue where user discriminator was written without leading zeroes. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- [JSON] Fixed an issue where the application sometimes crashed with an error saying `']' invalid without a matching open`, which was just a validation message that masked the actual error behind the failure. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- Fixed an issue where progress was not reported correctly if the channel didn't have any messages in the specified time range.
+
+### v2.26.1 (06-Feb-2021)
+
+- [CLI] Added support for file name templates, which allow you to dynamically generate output file names based on channel and guild metadata. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- Fixed an issue where the application sometimes crashed with `Invalid snowflake` message when exporting chat logs that contained invalid or outdated mentions. (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+
+### v2.26 (29-Dec-2020)
+
+- [HTML] Added support for replies. (Thanks [@Sanqui](https://github.com/Sanqui))
+- [HTML] Improved styling of non-media attachments (regular files, i.e. not video, audio, or image). (Thanks [@Lucas LaBuff](https://github.com/96-LB))
+- [HTML] Improved initial export performance.
+- [JSON] Relaxed escaping rules for unicode characters. (Thanks [@Sanqui](https://github.com/Sanqui))
+- [JSON] Added support for replies. (Thanks [@Sanqui](https://github.com/Sanqui))
+- [CLI] Added channel names to errors shown on failures when exporting multiple channels. (Thanks [@Sanqui](https://github.com/Sanqui))
+- [CLI] Added support for passing message IDs (snowflakes) to `--after` and `--before` options. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- Files downloaded by the "download referenced media" option now have their dates set according to the `Last-Modified` header provided by Discord CDN. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- Fixed an issue where the application sometimes crashed with `NullReferenceException` when retrying a failed HTTP request.
+- Migrated to Discord API v8.
+
+### v2.25 (23-Nov-2020)
+
+- [JSON] Added `mentions` property to the output. This contains users referenced inside the message text, but doesn't include mentions in embeds. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- [HTML] Added better previews for attached video and audio. They are now rendered using a browser native player element. The actual file path can still be retrieved by right clicking and selecting "Copy file path". (Thanks [@sas41](https://github.com/sas41))
+- [CLI] Fixed an issue where using `--media` option without providing a rooted path via `--output` option triggered an error.
+- [CLI] Fixed an issue where using `--reuse-media` option without also providing `--media` option was accepted, but didn't actually do anything. Now this produces an error instead. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+
+### v2.24 (24-Oct-2020)
+
+- [CLI] Updated to [CliFx v1.5](https://github.com/Tyrrrz/CliFx), which brings some UX improvements.
+- [GUI] Added dark mode, which can be enabled in settings. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- [GUI] Improved the UX in a few minor places.
+- [JSON] Added `embed.color` property to the output. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- Added additional date formats: `unix` to write dates as a unix timestamp and `unixms` for the milliseconds version. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- Added retry policy for downloading media content. This is mostly a workaround for transient failures that sometimes may occur when downloading assets referenced from embeds. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))
+- Added an option to reuse already downloaded media to avoid redundant network requests. It can be enabled in settings in GUI, or by passing `--reuse-media` in CLI. To facilitate this feature, the file name strategy has been changed as well -- now instead of relying on the original file name and adding `(n)` to the end in case of duplicates, a URL hash is injected in every file name. This also means that when the "reuse media" option is disabled, existing files inside the media directory may be overwritten. (Thanks [@Andrew Kolos](https://github.com/andrewkolos))

 ### v2.23 (14-Sep-2020)

 - [CLI] Added a command to export all channels across all servers. Use `exportall` to do it. (Thanks [@wyattscarpenter](https://github.com/wyattscarpenter))

+# Contributing
+
+DiscordChatExporter accepts contributions in the form of issues and pull requests.
+
+## Creating issues
+
+If you have a feature suggestion or want to report a bug, you are welcome to create an issue.
+
+Guidelines:
+
+- Avoid creating an issue if a similar one already exists. Look through existing open and closed issues first.
+- Keep your issue focused on one specific problem. If you have multiple suggestions or bug reports, please create separate issues for them.
+- Provide a descriptive title for your issue. Don't use generic titles like "A couple suggestions" or "Not working".
+- Provide more context in the body of the issue. If relevant, attach screenshots or screen recordings.
+- Remain civil and respectful when participating in discussions.
+
+## Creating pull requests
+
+If you want to contribute code to the project, you can do so by creating a pull request.
+
+Guidelines:
+
+- Make sure that there is an existing issue that describes the problem solved by your pull request. If there isn't one, please create it first.
+- Add a comment to the issue indicating that you want to submit a pull request for it. This can be a good opportunity to discuss possible solutions, finalize requirements, or ask questions.
+- Keep your pull request focused and as small as possible. If you want to contribute multiple unrelated changes, please create separate pull requests for them.
+- Follow the coding style and conventions already established by the project. When in doubt which style to use, ask in comments to your pull request.
+- If you want to start a discussion regarding a specific change you made, add a review comment to your own code. This can be used to highlight something important or to seek input from others.
+
+## 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
+```
