 ## Changelog
 
-### General
+### v2 changelog:
+
+#### General
 - **All commands are now hybrid commands** (`@bot.hybrid_command()`), supporting both prefix and slash usage. Thanks @Anonymous941 !
 - You can now run the bot with `-t TOKEN` to specify the Discord bot token.
 - **Improved error handling**: 
   - Unauthorized command usage now pings the user and says they are not authorized.
   - Missing required arguments are now reported to the user.
 - **Fixed`.replies_cmd` command** (replaced with a single `replies` hybrid command)
+- **Counting now support arithmetics**, (and SPOILER: it's not just eval())
+  - Bot now uses arithmeval, python library that gives bot ability to do basic math ( and not only )
+  - Now you can use Addition (+), True division (/), Floor division (//), Modulus (%), Multiplication (*), Exponentiation (^), Subtraction (-), and even pi (π), e, tau (τ), the golden ratio (φ), Euler-Mascheroni's gamma (gamma), the speed of light (c), Newton's gravitational constant (G), and Planck's constant (h). (IDK why you would use them)
 
-### Device Management
+#### Device Management
 - **New persistent device system**:
   - `devices` lists your devices or another user's devices.
   - `deviceadd` adds a device using a Discord modal form (slash command only).
   - `deviceremove <id>` removes a device by its per-user index.
   - `deviceinfo <user> <id>` shows info for a specific device.
-  - Devices are stored in devices.json
+  - Devices are stored in data/devices.json
 
 Don't know what this would be used for... :)
 
-### Regex Management
+#### Regex Management
 - **Regex block command now uses a modal** (slash command only) for adding new regex patterns.
 - **Regex list, toggle, and unblock commands now use 1-based indices** for user-facing commands (internally adjusted to 0-based). This was one of the earliest bugs present when we first implemented the regex system.
 
-
-### Replies System
+#### Replies System
 - **Removed explicit `replies` handling from `on_message`**, now handled by the hybrid command.
 
-### Miscellaneous
+#### Miscellaneous
 - **Update and hotupdate commands**:
   - `update` pulls the whole repo and restarts the bot.
   - `hotupdate` pulls the repo and reloads replies without restarting, replacing the old `updatereplies` command.
+- **Separate files**:
+  - One-file bot code was split into multiple files.
+  - Adding new features and reviewing them is now easier.
 - **General code cleanup and refactoring** for clarity and maintainability.
