Full changelog: v1.6.0...v1.7.0

1.6.0 [edot-php-1.6.0-release-notes]

Features and enhancements [edot-php-1.6.0-features-enhancements]

• Enabled opamp_polling_interval remote configuration option and improved remote configuration handling in native extension (#272) (PR #381)

Other [edot-php-1.6.0-other]

• ci(docs): scope pull_request triggers to integration branches (PR #372)

Full changelog: v1.5.0...v1.6.0

Features and enhancements

• Rebased on upstream OpenTelemetry PHP distro - EDOT PHP is now built on top of the upstream opentelemetry-php-distro (v0.4.0) as a vendor customization layer. This brings full alignment with the OpenTelemetry PHP ecosystem while retaining Elastic-specific features such as remote configuration. (#352, PR #367)
• Configuration options renamed to OTEL_PHP_* prefix - All configuration environment variables now follow the upstream OTEL_PHP_* naming convention (e.g. OTEL_PHP_LOG_LEVEL, OTEL_PHP_ENABLED). The previous ELASTIC_OTEL_* names are deprecated but still supported for backward compatibility - they are automatically mapped to their OTEL_PHP_* equivalents at startup. (#352)
• Added support for PHP 8.5 (upstream #58)
• Added user bootstrap config option (OTEL_PHP_USER_BOOTSTRAP) allowing users to specify a custom PHP file to be loaded during the distro bootstrap (upstream PR #76)
• Updated Laravel instrumentation to 1.7.0 (upstream PR #65)
• Updated OpenTelemetry SDK and instrumentation modules (upstream PR #62)
• Dependency shadowing/scoping with OTelDistroScoped\ prefix to avoid conflicts with user-installed OpenTelemetry packages (upstream PR #47)

Fixes

• Fixed internal inferred spans filtering for scoped namespace (upstream PR #56)

Other

• Updated documentation for the upstream naming conventions (#373, PR #374)
• Upstream PHP dependency notices are now propagated to the EDOT NOTICE file during build (#375, PR #376)
