What is the state of ABI compatibility between versions 4.2.0 and v4.3.0, and between v4.3.0 and v4.4.0? Are v4.2.0, v4.3.0 and v4.4.0 backwards compatible?

You should find that 4.2.0 is forward-compatible with both 4.3.0 and 4.4.0.

There was a small ABI break with 4.4.0, but this concerned the use of private symbols not part of the public API.

I referred the link here (https://abi-laboratory.pro/index.php?view=timeline&l=libtiff ) but it only has the ABI compatibility report till v4.2.0.

It might be worth contacting the maintainer of this facility to ask if they would be willing to update to include the more recent libtiff releases.

However, the maintainer of this facility also maintains the "abi-compliance-checker" tool. If you run this tool on the 4.2.0->4.3.0 and 4.3.0->4.4.0 releases, you can get the full API and ABI difference reports yourself and assess the changes.

Kind regards,

Roger
