Thanks for this @codeofdusk

Not sure, but this does not seem to be an update but rather standard diff match patch being replaced by fast diff match patch.
@codeofdusk, is it correct? If yes, the change log item should be modified.

Hi to all, I would rather want also new formulation in the changelog: * Improved speed and stability, when the console has been used with braille displays. This is particularly visible when there is a new content, and when the buffer in the console becomes large.

@zstanecic
It's strange that you noticed improvements, because The fix was a little different. And it shouldn't have affect braille.
Perhaps performance has increased due to the transition back to the fast diff match patch, but just in case, check if you have UIA notifications as diffing algorithm selected.

[zstanecic]

Hi, I am not using UIA notification, just for the testing purposes.

The change log entry is fine as-is, because:

• fast-diff-match-patch is a renaming of the existing package (same maintainer, same repo).
• No changes to Braille code were made. Any performance gains here are incidental.
