0.15.0 - 2025-05-01

Release Notes

• Add support for attributes of type any. (#707 by @lquerel)
• Add shell completion functionality. (#682 by @larrys)
• Add support for remote templates and policies. (#700 by @lquerel)
• Add Live Check for Spans via OTLP/JSON and loose Attributes via JSON/Text. (#630 by @jerbly)
• 💥 BREAKING CHANGE 💥 resource groups are now called entity groups. All JQ helper methods have been updated, but any template directly interacting with
  group.type may be broken. Use entity instead of resource group type in your Jinja templates. (#714 by @jsuereth)
• 💥 BREAKING CHANGE 💥 - All logging and diagnostics now go to stderr. Override diagnostics with --diagnostic-stdout. (#721 by @jerbly)
• Support for simplified Template Type Examples format where the key/attribute name is no longer included. (#710 by @jerbly)

[0.14.0] - 2025-04-10

What's changed

• Add support for 2 semconv registries. (#627 by @lquerel).
• Add support for annotations on attributes and groups. (#645 by @lquerel).
• 💥 BREAKING CHANGE 💥 - Upgrade to version 0.4.0 of regorus requires all v0 policies to be modified. Policy upgrade instructions here may help. (#651 by @jerbly).
• Stability level Deprecated is deprecated. Conventions should be deprecated via deprecated field and should keep the original stability. (#607 by @lmolkova).
• 💥 BREAKING CHANGE 💥 The constraints feature is no longer supported in semantic conventions yaml schema.
  The earliest version of semantic convention weaver is able to read has moved to 1.26.0. (#611 by @lmolkova).
• Make type property required on the semantic convention group (behind --future flag). (#611 by @lmolkova).
• Exclude attributes declared with code_generation.exclude annotations in semconv_attributes and other JQ attribute helpers. (#662 by @lmolkova)
• Sort metrics by name in all JQ helpers. (#573 by @lmolkova)

[0.13.2] - 2025-02-13

What's changed

• Add a note field to all deprecated variants and generate a formatted value when
  not provided in the semconv files. (#602 by @lquerel).

[0.13.1] - 2025-02-12

What's changed

• For issue #596 - Fix the Jinja deprecated test to accept the
  new deprecated format. (#597 by @lquerel).

[0.13.0] - 2025-02-07

What's changed

• Breaking Change: Introduced a new weaver registry diff command to generate a diff report between two versions of
  the semantic convention registry. This PR introduces a breaking change in the semantic conventions schema. While the
  text-based deprecated field is still supported for compatibility reasons, future semantic conventions should use the
  new deprecated structured format. (#400 by @lquerel).

  • The deprecated field is now a structured field defining the precise reason for deprecation. The semantic
    conventions must be updated to adopt this new format.
  • The changes related to the deprecated field (i.e., string → struct) also have a potential impact on certain
    templates that reference the deprecated field as containing text. These templates will need to be updated to use
    the brief field, which provides a textual explanation of the reasons for the deprecation.

• Improvement of comment generation: removal of <p> tags that precede @ Javadoc tags.
  (#574 by @trask).

• For Issue #564 - Require attributes and event fields to have stability: Added warnings for missing stability
  on: Attributes, Enum members in attributes, Event AnyValues, Enum members in AnyValues. (#568 by @jerbly).

• For issue [#569](Add include_stability config into semconv_grouped_attributes): is_experimental returns true by default. (#570 by @jerbly).

• Added an OTLP receiver to Weaver to prepare for the weaver registry live-check command. (see #548 by @lquerel)

• Add is_array filter and test for AttributeType. (#540 by @arthurDiff).

• Refactored CLI registry commands to remove some duplication. Resolving the registry with policy checks is common for
  generate, resolve and check. (#536 by @jerbly).

  • Added missing after_resolution policy checks to generate and resolve through the common code.
  • Removed the deprecated --registry-git-sub-dir option.
  • Fixed bug in check if --skip-policies was specified then it would not fail for any validation errors.

• Semantic Conventions Issue #1513 - Make span_kind required in yaml and break down multi-kind span
  definitions - (#542 by @jerbly).

  • Updated the EBNF and JSON schema to define span_kind as mandatory for span group types. Added a group validity
    check as a warning.

• First iteration of the new command: registry emit. Emits a semantic convention registry as example spans to your
  OTLP receiver. This may be useful in testing/simulation scenarios. (#549 by @jerbly)

• For issue [#569](Add include*stability config into semconv_grouped_attributes): added stable_only boolean flag as a parameter for
  semconv_signal, semconv_grouped_attributes, and other semconv*\*JQ semconv helpers. Whenstable_onlyis set totrue,
  corresponding helper function returns stable conventions only. If the flag is not set or set to false, stability filtering does not apply.
  It's recommended to use stable_onlyflag instead ofexclude_stability parameter.
  (#588 by @lmolkova)

[0.12.0] - 2024-12-09

What's changed

• Issue #502 - Support stability definitions from OTEP 232 - (#504 by @jerbly).
  • Stability enum now has these variants: stable, development, deprecated, alpha, beta, release_candidate
  • unmaintained is not supported yet.
  • experimental is still accepted when parsing but aliased to development.
  • The minijinja test, experimental, now returns true for any variant other than stable.
  • EBNF and JSON schema updated to define the new enum without the experimental variant.
• Issue #301 - Warn against usage of allow_custom_values. (#514 by @jerbly).
• Fixed rego typos, attrigute and deprecaded (#517 by @jerbly).
• Create better HTML comment parser - Allow more semconv snippet headers (#512 by @jsuereth).
• Add javadoc

  tag after lists (#511 @trask).

• Javadoc

  tags should only precede paragraphs (#510 by @trask).

• More consistent newline behavior (#509 by @trask).
• Add test cases to cover a paragraph after a list (#508 by @trask).

Important note: Our CI/CD pipeline has been updated to use Rust cross-compilation, significantly speeding up the ARM
target (see [#506](#506, thanks to @bernot-dev). If you encounter any
issues on ARM, please let us know as soon as possible. Thank you!

[0.11.0] - 2024-12-05

What's changed

• Detect duplicate group ids, group names, and metric names. (#382 by lquerel).

• Update semconv schema, syntax doc and validity check to correctly define stability as optional for attribute groups. (#467 by @jerbly).
• Fix issue #405 - Updated the EBNF and JSON schema to define the extends or attributes requirement mandatory for all group types except metric and event. Added a group validity check as a warning. (#494 by @jerbly).
• Allow adding a description when using opt_in requirement level ([#392](https://github.com/open-telemetry...
