IMPORTANT licensing update: libpng license v2
|
|
|
|
|
---------------------------------------------
|
|
|
|
|
|
|
|
|
|
The new libpng license comprises the terms and conditions from the zlib
|
|
|
|
|
license, and the disclaimer from the Boost license.
|
|
|
|
|
|
|
|
|
|
The legacy libpng license, used until libpng-1.6.35, is appended to the
|
|
|
|
|
new license, following the precedent established in the Python Software
|
|
|
|
|
Foundation License version 2.

From now on, the list of contributing authors shall be maintained in a
|
|
|
|
|
separate AUTHORS file. The lists of previous contributing authors,
|
|
|
|
|
mentioned in the legacy libpng license and considered to be an integral
|
|
|
|
|
part of that license, are kept intact, with no further updates.
