- [CLI] Added environment variables as fallback for `--token` and `--bot` options. They are `DISCORD_TOKEN` and `DISCORD_TOKEN_BOT` respectively.
- [GUI] Fixed a crash that occurred if the application was closed in the middle of an auto-update.
- [GUI] Added a link to project's wiki in the usage guide.
- [HTML] Added full spoiler support for text and images. To spoil the hidden content you now need to click on it, similarly to how it works in Discord. (Thanks [@FM-96](https://github.com/FM-96))
- [HTML] Updated grammar for consecutive single-line quotes. Previously they appeared separately, now they're grouped together as if it was one multi-line quote instead.
- [HTML] Fixed an issue where messages sent by the same bot but with different usernames were grouped together when they shouldn't be.
- [HTML] Updated grammar for single-line code blocks to accept double backticks as synonymous with single backticks. This change makes code blocks appear the same, whether they were inserted manually or using Discord's buggy markdown preview mode.
- [HTML] Fixed styling inconsistencies and other minor issues.
- [TXT/JSON] Fixed an issue where markdown was not parsed correctly in embed fields.
- [HTML] Changed markdown formatting in embeds so it follows the same set of rules as in Discord.
- Added channel category to the default file name used when exporting chat logs.
- [HTML/TXT/JSON] Added channel category to exported metadata.
- [CLI] Updated commands to also show channel category as well as channel name wherever relevant.
- Starting with this release, Docker images will have new tags: `stable` for latest stable release and `2.20` for a specific version.
- Added parallel exporting. This option allows you to export multiple channels faster by doing it in parallel. You can configure the parallel limit in settings (GUI) or with the `--parallel` option (CLI). Default value is `1`, which means there is no parallelization. Warning: be careful when using this option, as this will result in higher volume of concurrent HTTP requests sent to Discord, which might get you flagged. Use at your own risk.
- [HTML] Added support for user colors. User names are now appropriately colored according to the assigned guild roles.
- [HTML] Added support for nicknames. User names are replaced with nicknames where it's applicable. It's still possible to see the full user name by hovering your mouse over the nickname.
- [HTML] Improved styling for mentions to bring it more in line with how it looks in Discord.
- Added JSON export format. It's a structured data format which is easy to parse. If you're using DiscordChatExporter to export chat logs for further ingestion by another tool, this is most likely the format you will want to use.
- [GUI] You can now quickly jump to a specific channel in a list. For example, if you want to jump to a channel named "General", you can simply press the 'g' key in the channel list view. You can also press 'g', 'e' and 'n' in quick succession which will jump to the next channel that starts with "gen". This mechanic is consistent with other Windows applications.
- Fixed an issue where an empty file was produced when exporting a channel with no messages (for specified period). With the new behavior, no file will be created and instead a message will be shown to the user informing of the failure.
- [HTML/TXT] Added message count to the bottom of the file. This number shows how many messages were exported as part of the current file. Prior to 2.16 this number was present along with the rest of the metadata at the top, then removed due to changes in the exporter, and now brought back at the end of the file instead.
- [HTML] Fixed an issue where some emojis were not properly rendered.
- [GUI] Added a setting that lets you configure whether to remember the last used token. Previously it was the default behavior, but now you can disable it if you don't want the token persisted on your system.
- Migrated from .NET Framework to .NET Core. To run this and future versions of DiscordChatExporter you will need [.NET Core runtime for desktop apps](https://dotnet.microsoft.com/download/dotnet-core/3.1/runtime) (for GUI/CLI version on Windows) or [.NET Core base runtime](https://dotnet.microsoft.com/download/dotnet-core/3.1) (for CLI version on Windows, Linux or macOS).
- Reworked the exporter engine to render output using streaming data source. This means that only a very small portion of messages are cached in memory when exporting. In other words, you are only limited by storage space and not how much RAM you have, so you can now export terabytes of chat logs without hitting out of memory exceptions. I still recommend using partitions if you're exporting very large chat logs (250k+ messages) to HTML, unless you want your computer to catch fire when you try to open the export in browser.
- Changed how partitioned files are named, due to the fact that total number of partitions is no longer known ahead of time.
- [HTML/TXT] Removed message count from the metadata. Due to the fact that the messages are exported as they are streamed, total number of messages is not known ahead of time.
- [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.
- [HTML] Some other minor styling adjustments.
- [CSV] Replaced semicolons (;) with (,) as separators.
Please note that CSV export is most likely not going to receive future updates and will remain only as an option for those who wish to use it for text analysis. In other words, it won't contain any of the rich media features like embeds. If you're currently using CSV as a structured output to feed into your program, JSON output will replace that in the future.
- Added categories to channel list in GUI. Channels are now also grouped by category.
- Added ability to export multiple channels at once in GUI by selecting them with shift or ctrl keys.
- Added CLI command to export all available channels in a guild (`exportguild`).
- Added CLI command to export all direct message channels (`exportdm`).
- Added retry policy for 503 status code errors to prevent random crashes.
- Changed how channels are exported in GUI. Now you need to select them first and then click a button to export. You can also double click a single channel to export it as before.
- Improved default file name generation by adding date ranges and channel ID to the file name.
- Improved naming of files exported with partitioning.
- Improved usage instructions.
- Improved GUI layout and styling.
- Fixed an issue where dialogs would sometimes appear over other windows.
- Fixed an issue where launching DiscordChatExporter from Windows Start Menu would make it crash.
- Expanded CLI with new commands: `channels` (get a list of channels in a guild), `dm` (get a list of DM channels), `guilds` (get a list of guilds), on top of `export` (export chatlog).
- Added support for bot tokens as an alternative to user tokens. For GUI, use the button in the top-left to switch between user and bot token. For CLI, pass the `--bot` switch to indicate that the given token is a bot token.
