It isn't only #changeDirectory: method that is missing. Method #workingDirectoryPath: and instance variable workingDirectory are also missing.��

FileSystem >> changeDirectory: aPath

�� self workingDirectoryPath: (self resolve: aPath)

FileSystem >> workingDirectoryPath: aPath

�� aPath isAbsolute

�� ifFalse: [ self error: 'Cannot set the working directory to a relative path' ].

�� workingDirectory := aPath

To solve my problem, I implemented those and also fixed #initializeWithStore: and changed #workingDirectoryPath

FileSystem >> initializeWithStore: aStore

�� store := aStore.

�� workingDirectory := store defaultWorkingDirectory

FileSystem >> workingDirectoryPath

�� ^ workingDirectory

Those are from Pharo 5. However, this breaks Monticello (when opening Monticello Browser). A FileSystem instance has instance variable workingDirectory set to nil. This should be impossible. I set 'self halt' in #initializeWithStore:. It doesn't get triggered, which tells me the instance isn't created by normal way. I don't know what's going on there.

To fix it, I changed #workingDirectoryPath to

FileSystem >> workingDirectoryPath

�� workingDirectory ifNil: [

�� workingDirectory := store defaultWorkingDirectory ].

�� ^ workingDirectory

That solves my problem, but this is a specific tool. I don't know what other problems those changes will cause. This #ifNil: guard is not in Pharo 5, so that makes me worry. In general, the change in FileSystem gives impression that the it is intentional. But I haven't found the new Pharo 6.1 way to change working directory, if there's any.

Thanks for reporting.
I do not remember an action around me for this change.
Do you have the definition in Pharo 50 at hand?
