@@ -28,6 +31,47 @@ Bug fixes:
 
  - odd length RLE4 runs in BMP images were decoded incorrectly.
 
+ - pkg-config could sometimes return a library that was in a directory
+   EU::MM / $Config{libpth} doesn't know about, but the compiler did.
+   If no -L is included in the pkg-config library information check if
+   EU::MM can find the library, and if not, search our configured
+   directories and insert that into the library flags.
+   https://rt.cpan.org/Ticket/Display.html?id=75869
+
+ - Imager::Probe can now probe for libraries with dependent libraries,
+   common for static linking, eg. libpng requires libz.
+   https://rt.cpan.org/Ticket/Display.html?id=74043
+
+ - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
+
+ - added alternative probe configurations that try to link libz, to
+   handle a statically linked libpng.
+   https://rt.cpan.org/Ticket/Display.html?id=74043
+
+ - if a probe includes testcode, Imager::Probe now checks that code as
+   part of the process of checking each configuration rather than as a
+   post test of the found configuration.  This allows alternate
+   configurations to be checked if a matching but non-working
+   configuration is found.
+   https://rt.cpan.org/Ticket/Display.html?id=74043
+
+Other changes:
+
+ - when reading or writing images via callbacks, the default callbacks
+   now push an error message indicating that a required callback was
+   called but not supplied.
+   https://rt.cpan.org/Ticket/Display.html?id=76782
+
+ - clarify which callbacks are required for reading and writing TIFF
+   images.
+
+ - improve logging for creation of callback I/O layers.
+
+ - a little more documentation for Imager::Probe.
+
+ - the i_get_file_background() and i_get_file_backgroundf() APIs now
+   return int to indicate whether the i_background tag was found.
