 ## [Unreleased]
 
+## [2020.06.22]
+### Added
+- Auto case-sensitive & case-insensitive switch for searches
+- Vim plugin `airblade/vim-gitgutter` to show Git diff in the sign column next
+to line numbers in editor windows.
+- Vim plugin `Xuyuanp/nerdtree-git-plugin` to show Git status flags on NERDTree.
+- Highlight on search result & custom highlight colour.
+- Added global git config `credential.helper cache` for macOS user as
+`osxkeychain` is not available on Linux.
+
+### Changed
+- Default shell for Vim to `bash`.
+- Backspace to allow backspcaing over everthing in insert mode like most usual
+editors.
+- `cursorline` is now enabled by default.
+
+### Fixed
+- Heavy delay on shortcut `<<` while decreasing indent by reducing the
+`timeoutlen` to `100`(0.1s).
+- Text being moved to new line automatically at position `72` as Vim setting
+`textwidth` has been overriden by `ftplugin` for filetype `gitcomit.
+Implemented an `autocmd` to override it back to `textwidth=0`.
+- 1st file opened will notshow line numbers and colour column if Vim is
+initialised with cmd `vi`/`vim` due to the `autocmd` set to hide those items
+on `YouCompleteMe` preivew windo overrides the settings. Implemented a new
+`autocmd` which fixed this issue.
+
+### Removed
+- Vim plugin `jiangmiao/auto-pairs` as it somehow messes with the indents for
+bracket closures.
