Arabic Mark Transient Reordering Algorithm have been updated to revision 6. (Khaled Hosny)

New API:
+HB_BUFFER_FLAG_VERIFY
+HB_OT_TAG_MATH_SCRIPT

3.3.2
Revert splitting of pair positioning values introduced in 3.3.0 as it proved problematic. (Behdad Esfahbod)
3.3.1
Fix heap-use-after-free in harfbuzz-subset introduced in previous release. (Garret Rieger)
3.3.0
Improved documentation. (Matthias Clasen)
Internal code cleanup, using C++ standard library more. (Behdad Esfahbod)
The low 16-bits of face index will be used by hb_face_create() to select a face inside a font collection file format, while the high 16-bits will be used by hb_font_create() to load the named instance. (Behdad Esfahbod)
Glyph positions and other font metrics now apply synthetic slant set by hb_font_set_synthetic_slant(), for improved positioning for synthetically slanted fonts. (Behdad Esfahbod)
Fixed unintentional locale dependency in hb_variation_to_string() for decimal point representation. (Matthias Clasen)
When applying pair positioning (kerning) the positioning value is split between the two sides of the pair for improved cursor positioning between such pairs. (Behdad Esfahbod)
Introduced new HB_GLYPH_FLAG_UNSAFE_TO_CONCAT, to be used in conjunction with HB_GLYPH_FLAG_UNSAFE_TO_BREAK for optimizing re-shaping during line breaking. Check the documentation for further details. (Behdad Esfahbod)
Improved handling of macrolanguages when mapping BCP 47 codes to OpenType tags. (David Corbett)
New API:
+HB_GLYPH_FLAG_UNSAFE_TO_CONCAT
+hb_segment_properties_overlay()
+hb_buffer_create_similar()
+hb_font_set_synthetic_slant()

+hb_font_get_var_coords_design()
3.2.0
harfbuzz library improvements:
Fixed shaping of Apple Color Emoji flags in right-to-left context. (Behdad Esfahbod)
Fixed positioning of CFF fonts in HB_TINY profile. (Behdad Esfahbod)
OpenType 1.9 language tags update. (David Corbett)
Add HB_NO_VERTICAL config option. (Behdad Esfahbod)
Add HB_CONFIG_OVERRIDE_H for easier configuration. (Behdad Esfahbod)

- Changelog
Release 2.4.6 Sun February 20 2022
Bug fixes:
#566 Fix a regression introduced by the fix for CVE-2022-25313
in release 2.4.5 that affects applications that (1)
call function XML_SetElementDeclHandler and (2) are
parsing XML that contains nested element declarations
(e.g. "<!ELEMENT junk ((bar|foo|xyz+), zebra*)>").
Release 2.4.5 Fri February 18 2022
Security fixes:
#562 CVE-2022-25235 -- Passing malformed 2- and 3-byte UTF-8
sequences (e.g. from start tag names) to the XML
processing application on top of Expat can cause
arbitrary damage (e.g. code execution) depending
on how invalid UTF-8 is handled inside the XML
processor; validation was not their job but Expat's.
Exploits with code execution are known to exist.
#561 CVE-2022-25236 -- Passing (one or more) namespace separator
characters in "xmlns[:prefix]" attribute values
made Expat send malformed tag names to the XML
processor on top of Expat which can cause
arbitrary damage (e.g. code execution) depending
on such unexpectable cases are handled inside the XML
processor; validation was not their job but Expat's.
Exploits with code execution are known to exist.
#558 CVE-2022-25313 -- Fix stack exhaustion in doctype parsing
that could be triggered by e.g. a 2 megabytes
file with a large number of opening braces.
Expected impact is denial of service or potentially
arbitrary code execution.
#560 CVE-2022-25314 -- Fix integer overflow in function copyString;
only affects the encoding name parameter at parser creation
time which is often hardcoded (rather than user input),
takes a value in the gigabytes to trigger, and a 64-bit
machine. Expected impact is denial of service.
#559 CVE-2022-25315 -- Fix integer overflow in function storeRawNames;
needs input in the gigabytes and a 64-bit machine.
Expected impact is denial of service or potentially
arbitrary code execution.

This script is orphaned: It was only used while upgrading to Core Update
89, sitting around in /usr/sbin/ doing nothing ever since.
Keeping it there won't do any harm. On the other hand, dragging an
unused script around on our installations does not make sense either.

"Notes for BIND 9.16.26
Feature Changes
The DLZ API has been updated: EDNS Client-Subnet (ECS) options sent
by a client are now included in the client information sent to DLZ
modules when processing queries. [GL #3082]
Bug Fixes
Previously, recvmmsg support was enabled in libuv 1.35.0 and 1.36.0,
but not in libuv versions 1.37.0 or greater, reducing the maximum
query-response performance. This has been fixed. [GL #3095]
A failed view configuration during a named reconfiguration procedure
could cause inconsistencies in BIND internal structures, causing
a crash or other unexpected errors. This has been fixed. [GL #3060]
Previously, named logged a “quota reached” message when it hit its
hard quota on the number of connections. That message was
accidentally removed but has now been restored. [GL #3125]
Build errors were introduced in some DLZ modules due to an
incomplete change in the previous release. This has been fixed. [GL
#3111]"
