n/openssh-8.2p1-x86_64-1.txz: Upgraded.
Potentially incompatible changes:
* ssh(1), sshd(8): the removal of "ssh-rsa" from the accepted
CASignatureAlgorithms list.
* ssh(1), sshd(8): this release removes diffie-hellman-group14-sha1
from the default key exchange proposal for both the client and
server.
* ssh-keygen(1): the command-line options related to the generation
and screening of safe prime numbers used by the
diffie-hellman-group-exchange-* key exchange algorithms have
changed. Most options have been folded under the -O flag.
* sshd(8): the sshd listener process title visible to ps(1) has
changed to include information about the number of connections that
are currently attempting authentication and the limits configured
by MaxStartups.

Subject: [PATCH] REG: Fix unwanted cache flush in Freetype engine
|
|
|
|
The Freetype cache was almost completely disabled by
|
|
134c6db8587a8ce156d4fa31ffa62605821851b2 because after that
|
|
change, the lockedAlphaMapForGlyph() function would no longer
|
|
cut off early for empty glyphs like spaces, but rather go
|
|
through all alpha map functions before it realized that there
|
|
was nothing to render. This would in turn invalidate the cache
|
|
for every empty glyph, causing all glyphs to be rerendered for
|
|
every isolated word.
|
|
|
|
This change adds back a cut off. This is only needed in the
|
|
lockedAlphaMapForGlyph() function, since the superclass implementation
|
|
of the other alpha map functions already contains a cut off for
|
|
width/height == 0.
|
|
|
|
[ChangeLog][Qt Gui][Text] Fixed a performance regression in Freetype
|
|
engine that was introduced in Qt 5.5.
