- 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.
