+## 0.6.0
+
+Released on 23/07/2021
+
+> 🍹 Summer update 2021 🍨
+
+- **Open any file** in explorer:
+  - Open file with default program for file type with `<V>`
+  - Open file with a specific program with `<W>`
+- **Themes**:
+  - You can now set colors for 26 elements in the application
+  - Colors can be any RGB, also **CSS colors** syntax is supported (e.g. `aquamarine`)
+  - Configure theme from settings or import from CLI using the `-t <theme file>` argument
+  - You can find several themes in the `themes/` directory
+- **Keyring support for Linux**
+  - From now on keyring will be available for Linux only
+  - Read the manual to find out if your system supports the keyring and how you can enable it
+  - libdbus is now a dependency
+  - added `with-keyring` feature
+  - **❗ BREAKING CHANGE ❗**: if you start using keyring on Linux, all the saved password will be lost
+- **In-app release notes**
+  - Possibility to see the release note of the new available release whenever a new version is available
+  - Just press `<CTRL+R>` when a new version is available from the auth activity to read the release notes
+- **Installation script**:
+  - From now on, in case cargo is used to install termscp, all the cargo dependencies will be installed
+- **Start termscp from configuration**: Start termscp with `-c` or `--config` to start termscp from configuration page
+- Enhancements:
+  - Show a "wait" message when deleting, copying and moving files and when executing commands
+  - Replaced all `...` with `…` in texts
+  - Check if remote host is valid in authentication form
+  - Check if port number is valid in authentication form
+  - From now on, if you try to leave setup without making any change, you won't be prompted whether to save configuration or not
+- Bugfix:
+  - Fixed broken input cursor when typing UTF8 characters (tui-realm 0.3.2)
+  - Fixed save bookmark dialog: you could switch out from dialog with `<TAB>`
+  - Fixed transfer interruption: it was not possible to abort a transfer if the size of the file was less than 65k
+  - Changed `Remote address` to `Remote host` in authentication form
+- Dependencies:
+  - Added `argh 0.1.5`
+  - Added `open 1.7.0`
+  - Removed `getopts`
+  - Updated `rand` to `0.8.4`
+  - Updated `textwrap` to `0.14.2`
+  - Updated `tui-realm` to `0.4.3`
+

 Major termscp releases will now be seasonal, so expect 4 major updates during the year.
 
-Planned for *🏄 Summer update 🌴*:
+Planned for *🍁 Autumn update 🍇*:
+
+- **Configuration profile for bookmarks 📚**: Basically this feature adds the possibility to have a specific setup for a certain host, instead of having only one global configuration.
+- **Self-update ⬇️**: In order to increase users updating termscp, I want to provide the possibility to  update termscp directly from application, when a new update is available.
+- **AWS S3 support 🪣**: I'll use `rust-s3` library to implement this. This is really big **Maybe** for the autumn update and might be moved to the Winter update.
+
+Planned for *❄️ Winter update ⛄*:
 
-- **Keyring-rs on Linux 🔐**: Check for updates in [this issue](https://github.com/veeso/termscp/issues/2)
 - **SMB Support 🎉**: This will require a long time to be implemented, since I'm currently working on a Rust native SMB library, since I don't want to add new C-bindings. ~~Fear the 🦚~~
-- **Open files with any application ☄️**: possibility to open files of any kind and with any application directly inside termscp. This will be achieved through this awesome crate [open-rs](https://github.com/Byron/open-rs).
 
-To be planned:
+Along to new features, termscp developments is now focused on UX and performance improvements, so if you have any suggestion, feel free to open an issue.
-
-- **Themes provider 🎨**: I'm still thinking about how I will implement this, but basically the idea is to have a configuration file where it will be possible to define the color schema for the entire application. I haven't planned this release yet
-- **Configuration profile for bookmarks 📚**: I would like to, but I still have to analyze it.
-- **AWS S3 support 🪣**: There is already a library for AWS S3, but this is really on bottom of my implementation list at the moment, due to interest and I don't really have a system where to test it.

+Open and open with commands are powered by [open-rs](https://docs.rs/crate/open/1.7.0).

+- **Windows** users: you don't have to worry about it, since the crate will use the `start` command.

+- **WSL** users: *wslview* is required, you must install [wslu](https://github.com/wslutilities/wslu).
+
+> Q: Can I edit remote files using the view command?  
+> A: No, at least not directly from the "remote panel". You have to download it to a local directory first, that's due to the fact that when you open a remote file, the file is downloaded into a temporary directory, but there's no way to create a watcher for the file to check when the program you used to open it was closed, so termscp is not able to know when you're done editing the file.

+As said before, bookmarks are saved in your configuration directory along with passwords. Passwords are obviously not plain text, they are encrypted with **AES-128**. Does this make them safe? Absolutely! (except for BSD and WSL users 😢)

-On Linux and BSD, on the other hand, the key used to encrypt your passwords is stored on your drive (at $HOME/.config/termscp). It is then, still possible to retrieve the key to decrypt passwords.

+#### Linux Keyring
+
+We all love Linux thanks to the freedom it gives to the users. You can basically do anything you want as a Linux user, but this has also some cons, such as the fact that often there is no standard applications across different distributions. And this involves keyring too.
+This means that on Linux there might be no keyring installed on your system. Unfortunately the library we use to work with the key storage requires a service which exposes `org.freedesktop.secrets` on D-BUS and the worst fact is that there only two services exposing it.
+
+- ❗ If you use GNOME as desktop environment (e.g. ubuntu users), you should already be fine, since keyring is already provided by `gnome-keyring` and everything should already be working.
+- ❗ For other desktop environment users there is a nice program you can use to get a keyring which is [KeepassXC](https://keepassxc.org/), which I use on my Manjaro installation (with KDE) and works fine. The only problem is that you have to setup it to be used along with termscp (but it's quite simple). To get started with KeepassXC read more [here](#keepassxc-setup-for-termscp).
+- ❗ What about you don't want to install any of these services? Well, there's no problem! **termscp will keep working as usual**, but it will save the key in a file, as it usually does for BSD and WSL.

+## Themes 🎨
+
+Termscp provides you with an awesome feature: the possibility to set the colors for several components in the application.
+If you want to customize termscp there are two available ways to do so:
+
+- From the **configuration menu**
+- Importing a **theme file**
+
+In order to create your own customization from termscp, all you have to do so is to enter the configuration from the auth activity, pressing `<CTRL+C>` and then `<TAB>` twice. You should have now moved to the `themes` panel.
+
+Here you can move with `<UP>` and `<DOWN>` to change the style you want to change, as shown in the gif below:
+
+![Themes](../assets/images/themes.gif)
+
+termscp supports both the traditional explicit hex (`#rrggbb`) and rgb `rgb(r, g, b)` syntax to provide colors, but also **[css colors](https://www.w3schools.com/cssref/css_colors.asp)** (such as `crimson`) are accepted 😉. There is also a special keywork which is `Default`. Default means that the color used will be the default foreground or background color based on the situation (foreground for texts and lines, background for well, guess what).
+
+As said before, you can also import theme files. You can take inspiration from or directly use one of the themes provided along with termscp, located in the `themes/` directory of this repository and import them running termscp as `termscp -t <theme_file>`. If everything was fine, it should tell you the theme has successfully been imported.
+
+### Styles 💈
+
+You can find in the table below, the description for each style field.
+Please, notice that **styles won't apply to configuration page**, in order to make it always accessible in case you mess everything up

 ## Text Editor ✏
 
 termscp has, as you might have noticed, many features, one of these is the possibility to view and edit text file. It doesn't matter if the file is located on the local host or on the remote host, termscp provides the possibility to open a file in your favourite text editor.
