+## Changelog {#sec-release-0.2-changelog}
+
+[notashelf](https://github.com/notashelf):
+
+- Added two minimap plugins under `vim.minimap`. `codewindow.nvim` is enabled by default, while `minimap.vim` is
+  available with its code-minimap dependency.
+- A complementary plugin, `obsidian.nvim` and the Neovim alternative for Emacs' orgmode with `orgmode.nvim` have been
+  added. Both will be disabled by default.
+
+- Smooth scrolling for ANY movement command is now available with `cinnamon.nvim`
+
+- You will now notice a dashboard on startup. This is provided by the `alpha.nvim` plugin. You can use any of the
+  three available dashboard plugins, or disable them entirely.
+
+- There is now a scrollbar on active buffers, which can highlight errors by hooking to your LSPs. This is on by
+  default, but can be toggled off under `vim.visuals` if seen necessary.
+
+- Discord Rich Presence has been added through `presence.nvim` for those who want to flex that they are using
+  the _superior_ text editor.
+
+- An icon picker is now available with telescope integration. You can use `:IconPickerInsert` or `:IconPickerYank`
+  to add icons to your code.
+
+- A general-purpose cheatsheet has been added through `cheatsheet.nvim`. Forget no longer!
+
+- `ccc.nvim` has been added to the default plugins to allow picking colors with ease.
+
+- Most UI components of Neovim have been replaced through the help of `noice.nvim`. There are also notifications
+  and custom UI elements available for Neovim messages and prompts.
+
+- A (floating by default) terminal has been added through `toggleterm.nvim`.
+
+- Harness the power of ethical (`tabnine.nvim`) and not-so-ethical (`copilot.lua`) AI by those new assistant plugins.
+  Both are off by default, TabNine needs to be wrapped before it's working.
+
+- Experimental mouse gestures have been added through `gesture.nvim`. See plugin page and the relevant module for
+  more details on how to use.
+
+- Re-open last visited buffers via `nvim-session-manager`. Disabled by default as deleting buffers seems to be
+  problematic at the moment.
+
+- Most of NvimTree's configuration options have been changed with some options being toggled to off by default.
+
+- Lualine had its configuration simplified and style toned down. Less color, more info.
+
+- Modules where multiple plugin configurations were in the same directory have been simplified. Each plugin inside
+  a single module gets its directory to be imported.
+
+- Separate config options with the same parent attribute have been merged into one for simplicity.
