The underlying logging framework that Sitecore uses is Apache Log4Net, and this has not changed for a very long time (since early 6.x). Even the version used is the same, 1.2.11 I believe.
The pattern used for logging messages is also exactly the same between the versions:
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%4t %d{ABSOLUTE} %-5p %m%n" />
</layout>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%4t %d{ABSOLUTE} %-5p %m%n" />
</layout>
The Log Analyser tools relies on a certain pattern being used in the log4net log files. Since the underlying framework and the pattern have not changed it will work with the latest versions of Sitecore without any issues.
