YQL-21408: Replace MakeLangVersion with features.json

2026-07-15T12:13:42Z

#### Replace MakeLangVersion with features.json-based feature system ✎ - Introduces a new feature system based on `features.json` to manage language version dependencies instead of hardcoded `MakeLangVersion` calls - Replaces direct language version checks with references to named features defined in JSON configuration - Adds validation and initialization logic for features to ensure version consistency - Updates all existing language version checks to use the new feature-based approach - Centralizes feature version definitions in a single JSON file for better maintainability and clarity Autodescription by Yandex Code Assistant commit_hash:fe9823c0442060337a30186fd957ae294f1aa1c2

YQL-21374: Use runtime setting to make DateTime::Format signature backward compatible

2026-07-07T21:54:32Z

#### Backward compatibility for DateTime::Format signature ✎ - Introduces a runtime setting to control the availability of the `WriteOffsetWithColon` parameter in the `DateTime::Format` function, ensuring backward compatibility - The new setting `MakeWriteOffsetWithColonAvailableSince` allows controlling when the colon separator in time offsets becomes available, defaulting to version 2025.05 if not specified - Updates the ABI version to reflect the changes in the UDF interface and adds corresponding tests to verify the behavior under different configurations Autodescription by Yandex Code Assistant commit_hash:68a9855dc17000f9d47ab24e6727ef082f69504b

YQL-20095: Enable performance-move-const-arg

2026-06-24T10:13:06Z

https://clang.llvm.org/extra/clang-tidy/checks/performance/move-const-arg.html This check useful, as it shows, when a `std::move` is useless, so to expectations of a programmer are not aligned with reality. The most useful profit is to see `const T&` arguments, that are potentially can be replaced with `T`. Also disabled `CheckTriviallyCopyableMove`, see https://nda.ya.ru/t/Emvgx5Z67fpZY5 why. commit_hash:c80c264a9774721aabbac85b350ccdbb8b9a39a2
