 ## Notes
 
-- Text preview color needs to be readable enough, so it's worth rethinking (Now LightBlack).
-
 ## Unreleased
 
+## v2.0.0 (2022-11-11)
+
+### Changed
+
+- Migrated to yaml from toml: New config file will be created at the first launch (In this process you should enter the default command name or choose to use \$EDITOR). No more need to keep `config.toml`.
+- Add the fallback when config file cannot be read: In such a case, you can use the default Config.
+- HUGE refactoring overall.
+
+### Added
+
+- Horizontal split, in addtion to the vertical split. To toggle, press `s`.
+- Syntax highlighting (if possible) in previewed texts. To turn on, state `syntax_hightlight = true` in `config.toml`. you can also choose your theme, either from the default theme set or your favorite .tmtheme.
+- Enable scrolling in the preview space. `Alt + j / Up` goes down, `Alt + k` goes up. Experimental and may have some bugs, and with a big text file the perf issue may arise.
+- Search by keyword. Similar to the filter mode, but this feature do not manipulate the item list, just let users jump to the item that matches the keyword, just like Vim's `/`. `n` and `N` after `/` also works.
+- Show permissions on the footer (in unix only).
+
+### Fixed
+
+- Use `exists()` instead of `File::open()` to check whether the item path is valid when moving between direcotries. This allows Windows users to use this app at least with the basic commands.
+- Avoid `unwrap()` / `panic!` as possible and return the proper error.
+
+### Removed
+
+- Removed the filter mode, which is replaced by the keyword search.
+- Removed debug print in `make_config_if_not_exists`
+- Removed `use_full_width` and `item_name_length` in `config.toml`. Will always use full width of the terminal.
+
 ## v1.3.2 (2022-10-23)
 
 ### Added

-## v1.3.2 (2022-10-23)
+## v2.0.0 (2022-11-11)
 
-### Added
+### Changed
 
-- Add `std::panic::catch_unwind` to manually restore after a panic rewind. This allows the cursor to be restored and the screen cleared when this app panics.
+- Migrated to yaml from toml: New config file will be created at the first launch (In this process you should enter the default command name or choose to use \$EDITOR). No need to keep `config.toml`.
+- Add the fallback when config file cannot be read: In such a case, you can use the default config.
+- HUGE refactoring overall.
 
-### Fixed
+### Added
 
-- Fixed: Similar to v1.3.1, attempting to preview a symbolic link to a nonexistent file caused a panic. Now the preview shows `(file not readable)` for such a link.
+- Horizontal split, in addtion to the vertical split. To swtch between them, press `s`.
+- Syntax highlighting (if possible) in previewed texts. To turn on, state `syntax_hightlight: true` in `config.yaml`. you can also choose your theme, either from the default theme set or your favorite .tmtheme.
+- Enable scrolling in the preview space. `Alt + j / Down` goes down, `Alt + Up` goes up. Experimental and may have some bugs. Also, big text files can cause the performance issue.
+- Search by keyword. Similar to the filter mode, but this feature does not manipulate the item list: Just let users jump to the item that matches the keyword, like Vim's `/`. `n` and `N` after `/` also works.
+- Show permissions on the footer (in unix only).
