 NEWS file for libxml2
 
+v2.11.0: Apr 28 2023
+
+### Major changes
+
+Protection against entity expansion attacks, also known as "billion laughs"
+has been greatly improved. Malicious files should be detected reliably now
+and false positives should be reduced. It is possible though that large
+documents which make heavy use of entities are rejected now.
+
+This release finally fixes symbol visibility on UNIX systems. Internal
+symbols will now be hidden. While these symbols were never declared in public
+headers, it was still possible to declare them manually. Now this won't work.
+
+All symbol information has been removed from the ELF version script to fix
+link errors with --no-undefined-version. The version nodes are kept so it
+should still be possible to run binaries linked against older versions.
+
+About 90 memory errors in code paths handling malloc failures have been fixed.
+While these issues shouldn't impact security, this improves robustness under
+memory pressure.
+
+The XInclude engine has been reworked to properly support nested includes.
+
+Several cases of quadratic behavior in the XML push parser have been fixed.
+
+Refactoring has begun on some buffering and encoding code with the goal of
+simplifying this part of the code base and improving error reporting.
+
+Other highlights:
+
+- Consolidated private header files.
+- Major rework of the autoconf build.
+- Deprecated several outdated and internal functions.
+
+Special thanks to Google's Open Source Security Subsidies program for
+sponsoring much of the work on this release!
+
+Ongoing work on libxml2 relies on funding. For a list of important open
+issues see <https://gitlab.gnome.org/GNOME/libxml2/-/issues/507>
