 # Changelog
 
 Experimental changelog. Mostly based on [keepachangelog](https://keepachangelog.com/en/1.0.0/) except date format. a-c-f-r-o
+#todo .trans fix
 
-## [3.0.12] = 06.01.2021
+## Unreleased
+
+- More cool stuff coming soon
+
+## [4.0.2] - 03.0.3.2022
+
+- Fixed `.rero` not working due to a bug introduced in 4.0
+
+## [4.0.1] - 03.03.2022
+
+- Added `usePrivilegedIntents` to creds.yml if you don't have or don't want (?) to use them
+- Added a human-readable, detailed error message if logging in fails due to missing privileged intents
+
+## [4.0.0] - 02.03.2022
+
+### Added
+- Added `.deleteemptyservers` command
+- Added `.curtr <id>` which lets you see full information about one of your own transactions with the specified id
+- Added trovo.live support for stream notifications (`.stadd`) 
+- Added unclaimed waifu decay functionality
+  - Added 3 new settings to `data/gambling.yml` to control it:
+    - waifu.decay.percent - How much % to subtract from unclaimed waifu
+    - waifu.decay.hourInterval - How often to decay the price 
+    - waifu.decay.minPrice - Unclaimed waifus with price lower than the one specified here will not be affected by the decay
+- Added `currency.transactionsLifetime` to `data/gambling.yml` Any transaction older than the number of days specified will be automatically deleted
+- Added `.stock` command to check stock prices and charts
+- Re-added `.qap / .queueautoplay` 
+
+### Changed
+- CustomReactions module (and customreactions db table) has been renamed to Expressions.
+  - This was done to remove confusion about how it relates to discord Reactions (it doesn't, it was created and named before discord reactions existed) 
+  - Expression command now start with ex/expr and end with the name of the action or setting. 
+  - For example `.exd` (`.dcr`) is expression delete, `.exa` (`.acr`)
+  - Permissions (`.lp`) be automatically updated with "ACTUALEXPRESSIONS", "EXPRESSIONS" instead of "ACTUALCUSTOMREACTIONS" and "CUSTOMREACTIONS"
+  - Permissions for `.ecr` (now `.exe`), `.scr` (now `.exs`), `.dcr` (now `.exd`), `.acr` (now `.exa`), `.lcr` (now `.exl`) will be automatically updated
+  - If you have custom permissions for other CustomReaction commands
+  - Some of the old aliases like `.acr` `.dcr` `.lcr` and a few others have been kept
+- Currency output format improvement (will use guild locale now for some commands)
+- `.crypto` will now also show CoinMarketCap rank
+- Waifus can now be claimed for much higher prices (int -> long)
+- Several strings and commands related to music have been changed
+  - Changed `.ms / .movesong` to `.tm / .trackmove` but kept old aliases
+  - Changed ~~song~~ -> `track` throughout music module strings
+- Improved .curtrs (It will now have a lot more useful data in the database, show Tx ids, and be partially localized)
+  - [dev] Reason renamed to Note
+  - [dev] Added Type, Extra, OtherId fields to the database
+- [dev] CommandStrings will now use methodname as the key, and **not** the command name (first entry in aliases.yml)
+  - In other words aliases.yml and commands.en-US.yml will use the same keys (once again)
+- [dev] Reorganized module and submodule folders  
+- [dev] Permissionv2 db table renamed to Permissions 
+- [dev] Moved FilterWordsChannelId to a separate table
+
+### Fixed
+- Fixed an extra whitespace in usage part of command help if the command has no arguments
+- Possible small fix for `.prune` ratelimiting
+- `.gvc` should now properly trigger when a user is already in a gvc and changes his activity
+- `.gvc` should now properly detect multiple activities
+- Fixed reference to non-existent command in bot.yml
+- Comment indentation in .yml files should now make more sense
+- Fixed `.warn` punishments not being applied properly when using weighted warnings
+- Fixed embed color when disabling `.antialt`
+
+### Removed
+- Removed `.bce` - use `.config` or `.config bot` specifically for bot config  
+- Removed obsolete placeholders: %users% %servers% %userfull% %username% %userdiscrim% %useravatar% %id% %uid% %chname% %cid% %sid% %members% %server_time% %shardid% %time% %mention%  
+- Removed some obsolete commands and strings  
+- Removed code which migrated 2.x to v3 credentials, settings, etc...
+
+## [3.0.13] - 14.01.2022
+
+### Fixed
+
+- Fixed `.greetdm` causing ratelimits during raids
+- Fixed `.gelbooru`
+
+## [3.0.12] - 06.01.2022
 
 ### Fixed
 - `.smch` Fixed

-## Linux
-
-1. In order to migrate a bot hosted on **Linux**, first update your current version to the latest 2.x version using the 2.x installer, run the bot, and make sure it works. Then:
-    - Run the **old** installer with `cd ~ && wget -N https://github.com/Kwoth/NadekoBot-BashScript/raw/1.9/linuxAIO.sh && bash linuxAIO.sh`
-    - Run option **1** again
-    - You **MUST** Run the bot now to ensure database is ready for migration
-    - Type `.stats` and ensure the version is `2.46.5` or later
-    - Stop the bot
-2. Make sure your bot's folder is called `NadekoBot`
-    - Run `cd ~ && ls`
-    - Confirm there is a folder called NadekoBot (not nadekobot, in all lowercase)
-3. Migrate your bot's data using the new installer:
-    - Run the **new** installer `cd ~ && wget -N https://gitlab.com/Kwoth/nadeko-bash-installer/-/raw/master/linuxAIO.sh && bash linuxAIO.sh`
-    - The installer should notify you that your data is ready for migration in a message above the menu.
-    - Install prerequisites (type `1` and press enter), and make sure it is successful
-    - Download NadekoBot v3 (type `2` and press enter)
-    - Run the bot (type `3` and press enter)
-4. Make sure your permissions, custom reactions, credentials, and other data is preserved
-    - `.stats` to ensure owner id (credentials) is correct
-    - `.lcr` to see custom reactions
-    - `.lp` to list permissions
-5. 🎉 Enjoy. If you want to learn how to update the bot, click [here](../linux-guide/#update-instructions)

-## Manual

-⚠ NOT RECOMMENDED  
-⚠ NadekoBot v3 requires [.net 5](https://dotnet.microsoft.com/download/dotnet/5.0)
-
-1. In order to migrate a bot hosted **on Linux or from source on Windows**
-    - First update your current version to the latest 2.x version using the 2.x installer
-    - Then you **must** run the bot to prepare the database for the migration, and make sure the bot works prior to upgrade.
- Then:
-2. Rename your old nadeko bot folder to `nadekobot_2x`
-    - `mv NadekoBot nadekobot_2x`
-3. Build the new version and move old data to the output folder 
-    1. Clone the v3 branch to a separate folder 
-        - `git clone https://gitlab.com/kwoth/nadekobot -b v3 --depth 1`
-    2. Build the bot
-        - `dotnet publish -c Release -o output/ src/NadekoBot/`
-    3. Copy old data
-        - ⚠ Be sure you copy the correct command for your system!
-        - **Windows:** `cp -r -fo nadekobot_2x/src/NadekoBot/data nadekobot/src/NadekoBot/data`
-        - **Linux:** `cp -rf nadekobot_2x/src/NadekoBot/data nadekobot/src/NadekoBot/data`
-    4. Copy the database 
-        - `cp nadekobot_2x/src/NadekoBot/bin/Release/netcoreapp2.1/data/NadekoBot.db nadekobot/output/data`
-    5. Copy your credentials
-        - `cp nadekobot_2x/src/NadekoBot/credentials.json nadekobot/output/`
-4. Run the bot
-    - `cd nadekobot/output`
-    - `dotnet NadekoBot.dll`
-5. That's it. Just make sure that when you're updating the bot, you're properly backing up your old data.

+*** Please enable privileged intents ***
+
+Certain Nadeko features require Discord's privileged gateway intents.
+These include greeting and goodbye messages, as well as creating the Owner message channels for DM forwarding.
+
+How to enable privileged intents:
+1. Head over to the Discord Developer Portal https://discord.com/developers/applications/
+2. Select your Application.
+3. Click on `Bot` in the left side navigation panel, and scroll down to the intents section.
+4. Enable both intents.
+5. Restart your bot.
+
+Read this only if your bot is in 100 or more servers:
+
+You'll need to apply to use the intents with Discord, but for small selfhosts, all that is required is enabling the intents in the developer portal.
+Yes, this is a new thing from Discord, as of October 2020. No, there's nothing we can do about it. Yes, we're aware it worked before.
+While waiting for your bot to be accepted, you can change the 'usePrivilegedIntents' inside your creds.yml to 'false', although this will break many of the nadeko's features");
