Conclusion
There have now been multiple releases of adv3Lite so by now it should be settling down to be fairly stable, so it should be eminently safe to write a game in it, even though some bugs (hopefully relatively obscure ones by now) will doubtless remain.
At this stage it is unlikely that many (if any) features of the library will be substantially changed in future releases. As far as possible we'll try to ensure that everything described in this manual will continue to work as described, but we can't absolutely guarantee that nothing will change, since change may be unavoidable to implement some new feature or resolve some unanticipated difficulty. Any features of or code in the library not explicitly covered in this manual are liable to change without notice. That said, after so many releases it is unlikely that things will change very much.
A recent poll of TADS 3 authors on intfiction.org indicated that roughly half of them use adv3Lite, so thank you for your interest! I hope that the adv3Lite library may be able to serve some of your IF needs either now or in the future.
