+### v2.34 (10-Apr-2022)
+
+- [HTML] Reworked layout to be more consistent with Discord.
+- [HTML] Changed user profile picture dimensions from `128x128` to `512x512`. (Thanks [@Chris Helder](https://github.com/TheDude53))
+- [HTML] Improved image scaling for Chromium-based browsers. This should result in higher quality images across the entire export.
+- [HTML] Hovering over messages will now show short timestamps on the left, indicating the time that the individual messages of the group were sent.
+- [HTML] Using "download media" option will now also download scripts, styles, fonts, and other similar resources used by the export.
+- [HTML] Image attachments will now use the provided description as alt text.
+- [HTML] Fixed a few layout inconsistencies related to embeds.
+- [GUI] Added a few clickable links to the usage guide to make the process of locating tokens easier.
+
+### v2.33.2 (07-Mar-2022)
+
+- Actually fixed it this time.
+
+### v2.33.1 (07-Mar-2022)
+
+- Fixed an issue where the application silently failed to run if the system didn't have .NET Runtime 6.0.2 installed. If you continue seeing this issue, please uninstall all existing .NET runtimes from your computer and then try running the application again.
+
+### v2.33 (06-Mar-2022)
+
+- Added messages informing about war in Ukraine and available ways to help.
+- Added support for rendering stickers in HTML and JSON. Lottie-based stickers currently cannot be displayed in HTML exports (see [#803](https://github.com/Tyrrrz/DiscordChatExporter/issues/803)).
+- Added a new `reaction:` message filter which can be used to check if someone reacted to a message with a specific emoji. You can either pass the emoji name (e.g. `reaction:LUL`) or its ID (e.g. `reaction:41771983429993937`).
+- [GUI] Added auto-detection for dark mode. If your system is configured to prefer dark mode in applications, DiscordChatExporter will use it by default instead of light mode.
+- Fixed an issue which caused the export process to crash when downloading media files with extremely long file extensions. (Thanks [@Tomlacko](https://github.com/Tomlacko))
+- Fixed an issue which caused the export process to crash on invalid mentions.
+- [GUI] Fixed an issue where the time pickers used to specify export ranges always displayed time in 12-hour format, instead of respecting the system locale.
+
+### v2.32 (27-Jan-2022)
+
+- Token kind (user or bot) is now detected automatically. Removed the button to switch token kind in GUI. Option `-b|--bot` in CLI is now deprecated and does nothing.
+- Updated user token extraction guide to reflect the fact that devtools are no longer accessible in the desktop version of Discord client. The recommended workaround is to open Discord in browser. (Thanks [@Dhananjay-JSR](https://github.com/Dhananjay-JSR))
+- Fixed an issue which caused an error when parsing invalid date timestamps. Such timestamps are now rendered as "Invalid date", similarly to how the Discord client does it.
+- Fixed an issue which caused an error when parsing certain embed fields.
+- Fixed an issue which caused an error when parsing a mention to a user that has no username.
+- [GUI] Minor visual fixes.
+
 ### v2.31.1 (15-Dec-2021)
 
-- Fixed an issue which caused an exception when parsing certain custom emoji reactions.
+- Fixed an issue which caused an error when parsing certain custom emoji reactions.
 - [GUI] Improved user interface.
