1. Two great improvements for WiseUser v2.1.9 are: firstly, release the installation package for Linux. Secondly, some critical bugs are fixed. Further more, the module log information is stylized identically. The "quick start guide" has been packed into the installation.

2. We have fixed a critical bug: if a parallel view is active, switching to a new project would lead to crash.

3. Also We have fixed some bugs in "Browse SEGY Header" and "Browse FB File", which may lead to crash.

4. In the modules of "Encrypt SEGY" and "Segy to WDF", the encryption parameters are output explicitly to log.

5. The installation package for Linux is compiled on Ubuntu 22.04. because Ubuntu is the most widely used desktop Linux distribution.

6. Rocky Linux 9.6 is another OS we tested for WiseUser, due to its compatibility with Red Hat which runs widely in the seismic processing center.

7. Notes for the usage of WiseUser v2.1.9:
    (1) Given the dominant market share of Windows and entrenched user habits, a new version installation package for Windows 10/11 remains available.
    (2) Under Linux, data processing is faster compared to Windows by over 30%. For the users who work with large volumes of data, the Linux version of WiseUser is strongly recommended.
    (3) WiseUser v2.1.9 is free and allows the user to register one or more accounts on the cloud for convenience.
    (4) Avoid concurrent access to the same cloud account from different computers when processing WDF files to pick FB. Doing so may cause file corruption or synchronization conflicts within your cloud account.
    (5) While connecting to the internet, press F1 at any time, you can open the cloud-based help documentation(to be completed later).
    (6) At any time, click the menu of "Help->quick start guide" will display locally the "quick start guide" documents on the browser.
