+Overview of changes in Sysprof 45.rc
+====================================
+
+Changes since 45.beta:
+
+ * A Rust demangler is provided which can demangle some newer style
+   Rust symbols.
+ * The C++ and Rust legacy demanger has improved to handle some
+   scenarios where <> and :: should be used.
+ * The D-Bus section has gained support for search filtering.
+ * A busy indicator is now show when callgraphs are being generated or
+   updated to reflect changing view options.
+ * Improvements to sysprof-cli and sysprof-agent to support recent
+   capture features.
+ * sysprof-cli can now specify capture buffer size in number of pages
+   to help in situations where you want to avoid disk spillage.
+ * Zoom controls now stay sticky to the left.
+ * SysprofCollector will now try much harder for the peer to process
+   the mmap ring buffer before bailing so that the leak collector is
+   less likely to drop records.
+ * Sysprof now uses gtktimsort to sort records for a significant speed
+   improvement when loading large captures.
+ * Window titles now include documen title.
+ * Reduction in number of samples to normalize for various charts which
+   results in faster loading times. You can continue to zoom in to get
+   better details.
+ * A new scheduler details instrument is provided, which uses tracepoints
+   to track when processes were running and on what CPU.
+ * A new flamegraph is added for viewing profiling results. It is powered
+   by the same callgraph seen in the callgraph view, which means changes to
+   the callgraph can influence the flamegraph. Colorization is provided
+   by stack categorization in callgraphs.
+ * Categorization of Kernel symbols has been fixed.
+ * Callgraphs are now sorted incrementally to help keep the UI responsive
+   while loading the document.
+ * Accounting of weights for callgraphs has been improved to avoid double
+   counting summary values when recursion is used.
+ * A fix for a crash when pivoting to a new root in the callgraph.
+ * A new option to merge similar processes when generating callgraphs.
+ * A new option to filter out kernel processes has been added. This feature
+   is quite rudimentary and involves commandline sniffing. Improvements
+   are requested by those seeking more comprehensive filtering.
+ * Improvements to locating and symbolizing Flatpak processes.
+ * The files section has gained search filter support.
+
+Happy Hacking!
