Pixie Vizier Release:

New Features

• (#2196) PEM's can now limit the total memory used by Pixie's
  socket tracer buffers through the --total_conn_tracker_mem_usage
  command line flag or the PX_TOTAL_CONN_TRACKER_MEM_USAGE env var. This
  allows memory conscious users to have more predictable memory use when
  paired with PL_TABLE_STORE_TABLE_SIZE_LIMIT.- (#2194) Added --elf_reader_max_file_size flag to PEM. This
  flag allows memory conscious users to prevent the PEM from parsing large
  binaries in order to avoid large memory allocations.- (#2096) Added support for tracing TLS handshakes. This can be
  enabled with --stirling_enable_tls_tracing=1 or through the
  PX_STIRLING_ENABLE_TLS_TRACING environment variable. Until #2095 is
  addressed, this will disable tracing the plaintext within encrypted
  connections.

Bug Fixes

• (#2223) Fixed compatibility issues with Go 1.24's internal
  HTTP/2 implementation changes.- (#2198) Fixes an issue where ARM Container OS (COS) clusters
  running a 6.6.x kernel failed to start the socket tracer

Cleanup

• (#2181) Upgrade the pxapi python module's third party
  dependencies and support Python 3.11 through 3.13- (#2108) Update Go dynamic logging feature to support Go 1.17+
  binaries

Pixie Cloud Release:

New Features

• (#2062) Pixie Cloud can now disable executing modified pxl
  scripts via the PL_SCRIPT_MODIFICATION_DISABLED key in the
  pl-script-bundle-config ConfigMap. See reference manifests for more
  details.
• (#2065, #2091) Enhanced the px cli's deploy and collect-logs
  commands to surface when kernel headers aren't installed. This is a
  common source of bugs that can only be addressed by installing your
  distro's kernel headers.
