The most notable change here is linux-perf-data 0.10.2 which adds support for SIMPLEPERF_FILE sections, which gives us symbols for perf.data files from older versions of simpleperf. Supporting older versions of simpleperf is useful because it lets us profile on older versions of Android; even if you run a modern version of simpleperf on the host machine, on device you'll still end up using the version of simpleperf that shipped with Android, unless you're profiling a debuggable app or you're root.
