release v2.16.3

Fixed

• Fixes potential deadlock by updating dashmap dependency.
• Updates other dependencies to pull-in bugfixes.
• Improves memcache sampler reconnect logic.

release v2.16.2

Fixed

• Fixes scheduler runqueue latency BPF for newer kernels (>= 5.14) and those
  built with gcc >= 10
• Fixes issue with release 2.16.1

release v2.16.0

Added

• Adds a new process sampler which can monitor CPU and memory utilization for
  a process. (#282)

release v2.15.2

Fixed

• Fixes issue where release archives do not build successfully due to inclusion
  of vergen in the build script. (#279)

release v2.15.1

Fixed

• Fixes tcp/connection/accepted and tcp/connection/initiated metrics on
  kernel 5.10. (#266)
• Fixes tcp/receive/duplicate and tcp/receive/out_of_order metrics. (#267)

release v2.15.0

Changed

• Allow selective enablement of various BPF metrics. (#254)
• Support up to BCC 0.23.0 and makes it the new default version. (#256)
• Removed ssl support in http sampler to remove dependency on openssl. (#257)

Added

• Adds TCP jitter and connections accepted and initiated using BPF. (#247)
• Adds Pelikan specific stats to memcache sampler. (#249)
• Adds TCP packet drops counter using BPF. (#250)
• Adds TCP tail loss recovery and retransmit timeout using BPF. (#253)
• Adds TCP duplicate segment and out-of-order segment counters using BPF. (#255)

Fixed

• Improved handling of BPF initialization errors so that samplers will continue
  to initialize remaining BPF probes if fault tolerant error handling is
  enabled. (#259)

release v2.14.0

Added

• Adds new SRTT metric for TCP sampler using BPF. (#238)
• Adds new krb5kdc sampler to get telemetry on MIT Kerberos. (#241)

release v2.13.0

Fixed

• Interrupt sampler failed to sample all interrupts if it encountered an
  unexpected keyword. (#225)
• Interrupt sampler incorrectly initialized per-NUMA node counts for NVMe and
  network interrupts. (#226)
• Memory sampler failed to report some stats. (#227)
• CPU c-state sampling now handles older style c-state names. (#229)
• Prometheus metric exposition now includes type annotations and changes the
  format for percentiles to be encoded as a label value. This fixes collection
  with OpenTelemetry. (#230)

Changed

• Removed unused interrupt/serial metric from the interrupt sampler. (#228)

release v2.12.0

Fixed

• NTP sampler failed to build with musl toolchain. (#216)

Added

• New usercall sampler for probing arbitrary userspace functions in shared
  libraries.

release v2.11.1

Fixed

• HTTP and Memcache samplers reporting incorrect percentiles.
