@ -22,14 +22,17 @@ Released on FIXME: date
- **Execute** a command pressing `X`. This feature is supported on both local and remote hosts (only SFTP/SCP protocols support this feature).
- Enhancements:
- Input fields will now support **"input keys"** (such as moving cursor, DEL, END, HOME, ...)
- For developers:
- Activity refactoring
- Developed an internal library used to create components, components are then nested inside a View
- The new engine works through properties and states, then returns Messages. I was inspired by both React and Elm.
- Improved performance regarding configuration I/O (config client is now shared in the activity context)
- Fetch latest version from Github once; cache previous value in the Context Storage.
- Bugfix:
- Prevent resetting explorer index on remote tab after performing certain actions (list dir, exec, ...)
- SCP file transfer: prevent infinite loops while performing `stat` on symbolic links pointing to themselves (e.g. `mylink -> mylink`)
- Fixed a bug causing termscp to crash if removing a bookmark
- Fixed file format cursor position in the GUI
- For developers:
- Activity refactoring
- Developed an internal library used to create components, components are then nested inside a View
- The new engine works through properties and states, then returns Messages. I was inspired by both React and Elm.

//! ## Store
//!
//! `Store` is the module which provides the Context Storage.
//! The context storage is a storage indeed which is shared between the activities thanks to the context
//! The storage can be used to store any values which should be cached or shared between activities
