From the CHANGES:
Version 1.9
===========
genhtml:
- Improved wording for branch representation tooltip text
- Fixed vertical alignment of HTML branch representation
geninfo:
- Improved warning message about --initial not generating branch coverage data
- Debugging messages are now printed to STDERR instead of STDOUT
- Fixed problem with some .gcno files. Reported by gui@futarque.com.
(file.gcno: reached unexpected end of file)
- Fixed problem with relative build paths. Reported by zhanbiao2000@gmail.com.
(cannot find an entry for ^#src#test.c.gcov in .gcno file, skipping file!)
- Fixed problem where coverage data is missing for some files. Reported by
weston_schmidt@open-roadster.com
- Fixed problem where exclusion markers are ignored when gathering
initial coverage data. Reported by ahmed_osman@mentor.com.
- Fixed large execution counts showing as negative numbers in HTML output.
Reported by kkyriako@yahoo.com.
- Fixed problem that incorrectly associated branches outside of a block with
branches inside the first block
lcov:
- Fixed problem that made lcov ignore --kernel-directory parameters when
specifying --initial. Reported by hjia@redhat.com.
- Added --list-full-path option to prevent lcov from truncating paths in list
output
- Added lcov_list_width and lcov_list_truncate_max directives to the
lcov configuration file to allow for list output customization
- Improved list output
COPYING:
- Added license text to better comply with GPL recommendations
Version 1.8

gendesc:
- Fixed problem with single word descriptions
genhtml:
- Added support for branch coverage measurements
- Added --demangle-cpp option to convert C++ function names to human readable
format. Based on a patch by slava.semushin@gmail.com.
- Improved color legend: legend display takes up less space in HTML output
- Improved coverage rate limits: all coverage types use the same limits
unless specified otherwise
- Fixed CRLF line breaks in source code when generating html output. Based
on patch by michael.knigge@set-software.de.

coverage data (Can't use an undefined value as a HASH reference at genhtml
line 4441.)
- Fixed short-name option ambiguities

LCOV is a front-end around gcov, the GCC code coverage tool. It
collects the gcov data and creates HTML webpages showing coverage
rates using bar graphs and specific colors. It can also create
webpages for browsing the source code.
