pcp-6.0.0 (31 August 2022)
- Major changes:
1. Add version 3 PCP archive support: instance domain change-deltas,
Y2038-safe timestamps, nanosecond-precision timestamps, arbitrary
timezones support, 64-bit file offsets used throughout for larger
(beyond 2GB) individual volumes.
** Opt-in using the /etc/pcp.conf PCP_ARCHIVE_VERSION setting. **
** Version 2 archives remain the default (for next few years). **
2. Switch to using OpenSSL only throughout PCP (dropped NSS/NSPR);
this impacts on libpcp, PMAPI clients and PMCD use of encryption;
these are now configured and used consistently with pmproxy HTTPS
support and redis-server, which were both already using OpenSSL.
3. New nanosecond precision timestamp PMAPI calls for PCP library
interfaces that make use of timestamps. These are all optional,
and full backward compatibility is preserved for existing tools.
