Date: 2018-05-02

|
Initial Package Version: 20180414
|
||
|
Upstream Status: Applied
|
||
|
Origin: Upstream
|
||
|
Description: Three fixes, cherry-picked from svn.
|
||
|
|
||
|
r47469 Fix segfault in dvipdfm-x (XeTeX) on 1/2/4-bit transparent indexed PNGs.
|
||
|
|
||
|
r47470 Support poppler-0.64.0 (this one is critical for current BLFS).
|
||
|
|
||
|
r47477 Fix a ptex regression for discontinuous kinsoku table.
|
||
|
|
||
|
NB most updates in current svn are for ongoing development.
|
||
|
|
||
|
I have ignored r47476 (m-tx-0.63a) because the announcement at CTAN says this is
|
||
|
a minor correction which will not be moticed on most architectures.
