v1.5.4 (2023-01-09): ensures "." is in the PATH, for some convenience functionalities of tewiba with test files to work, such as running a test file directly as a standalone script. No need to upgrade if you did not have issues before. However, if you redistribute tewiba as part of a package, upgrading is a good idea, as tewiba may end up being used by people without a dot in their PATH.
