In 27.0.1 the "Highlight matching symbols under cursor" feature doesn't un-highlight symbols that were previously highlighted. See attached screenshot. This works as expected in in 27.0.0. This has been observed in document modes C/C++ and Ansi-C.
Also, some symbol coloring has changed to bold. See attached screenshots comparing 27.0.0 to 27.0.1.
This is on Windows 10, SlickEdit Pro 2022 (v27.0.1.0 64-bit Qt5),
