Obi 5.0 test releases

Obi 5.0 beta (released on September 6, 2023)

Obi 5.0 beta test release upgrades Obi to .NET 6 framework for keeping it abreast with the new technologies. This task became a high priority for year 2023 because Microsoft has stopped supporting .NET 4.0 framework from 2022 onwards.

This test release is mainly focused on upgrading Obi to .NET 6 and resolving the regression bugs. Only one enhancement is added to CSV export, for exporting comments of To-Do marks to the CSV file. Rest of the features are the same as Obi 4.8.

Version 5.0 beta will work on Windows 7, 8, 10 and 11. Please use version 4.8 for Windows Vista.

Note: On starting Obi first time after installation, a keyboard shortcuts error will be shown for resetting keyboard shortcut settings. Please press OK button and continue.

We are looking forward to your feedback, comments and bug reports for this major upgrade. Please send your feedback via email:
