v0.9.5

• Improved first user experience
  • Add "--reload" command for sending SIGHUP to daemon process
  • Show error message when configuration file is empty
• Experimental build support for Solaris
• System metrics: Various fixes
• Packaging: Add support for Ubuntu Precise / 12.04 LTS

v0.9.4

• Introduce "pganalyze-collector-helper": Setuid Binary that can be used to run
  privileged actions when the main collector is running as non-root (the default)
• Determine the correct distance between two collector runs (instead of assuming 600 seconds)
• Better monitoring for self-hosted systems
  • Collect missing Disk I/O statistics
  • Fix calculation logic for disk utilization
  • Collect kernel version and architecture
  • Don't monitor the local loopback network interface
  • Sort disk/partition/network interface names before output
  • Don't collect local system information when monitoring remote hosts
• Packaging
  • Update to Go 1.7
  • Systemd: Enforce memory limit of 256mb for the collector

v0.9.3

• Correctly identify PostgreSQL data directory and pg_xlog location
• Avoid potential NaN values in disk stats for self-hosted systems
• Don't write state file for dry runs by default

v0.9.2

• PostgreSQL 9.2, 9.3 and 9.6 Support
• Adjust default config and state file path to match packages
• Allow using postgres driver default values for connection credentials

v0.9.1

• Add support for logging to syslog instead of stderr
• Init scripts for systemd, upstart and sysvinit (see contrib/ directory)
• Packaging scripts for common Linux distributions (see packages/ directory)

v0.9.0

• First official release of new protocol buffers-based collector

v0.9.0rc8

• Significant restructuring of the codebase
  • We're now sending data using the protocol buffers format
  • Snapshot data is directly uploaded to S3
• Query, table and system statistics are diff-ed on the client side
• Support for monitoring system metrics on self-hosted systems is added again
• New safety mechanisms against stuck/slow collector runs

v0.9.0rc7

• Add support for RDS enhanced monitoring
• Simplify dependencies and document OSS licenses in use

v0.9.0rc6

• Bugfixes for AWS Instance Role handling

v0.9.0rc5

• Introduce new --diff-statements option (default off for now)
  • This calculates the diff for the counter values of pg_stat_statements on the client (i.e. collector),
    instead of the server for increased accuracy and protection against out-of-order processing
• Introduce "opts" to the snapshot, for indicating which options were chosen
• Never open more than 1 connection to the same database
  • This covers edge cases like sending a lot of SIGHUP signals
  • In case we detect more than 1 connection we error out and exit, to avoid
    clogging the database
• Use AWS EC2 instance role if no credentials are specified
