Full Changelog: v0.3.0-alpha...v0.7.0-alpha

Release v0.3.0-alpha

This release has deprecated support for the github.com/gorilla/mux instrumentation.

Added

• Add database/sql instrumentation (#240)
• Support Go 1.21. (#264)

Changed

• The function signature of "go.opentelemetry.io/auto/offsets-tracker/downloader".DownloadBinary has changed.
  It now has an additional flag indicating whether it'll build a dummy app for Go stdlib packages or not. ([#256]#256)
• The function signature of "go.opentelemetry.io/auto/offsets-tracker/target".New has changed.
  It now accepts a flag to determine if the returned Data is from the Go stdlib or not. ([#256]#256)
• Use UPROBE_RETURN to declare the common uprobe return logic (finding the corresponding context, setting up end time, and sending the event via perf buffer) ([#257]#257)
• BASE_SPAN_PROPERTIES as common fields (start time, end time, SpanContext and ParentSpanContext) for all instrumentations events (consistent between C and Go structs). ([#257]#257)
• Header guards in eBPF code. ([#257]#257)

Fixed

• Fix context propagation across different goroutines. (#118)
• The offset tracker can once again build binaries for the Go stdlib. ([#256]#256)
