Release v1.27.0 · go-delve/delve
Delve v1.27.0 has been released. The update includes new features, bug fixes, and improvements to the Go debugger.
Background
- Delve (aka "dlv") is the official debugger for the Go programming language, analogous to GDB for C/C++ or LLDB for Swift/Objective-C.
- This release (v1.27.0) drops support for older Go versions (1.19 and earlier) and introduces automatic stack unwinding — a major feature that lets developers trace the call stack more reliably, especially in complex concurrent code or when debugging crashes.
- Other highlights: a new "bits" command to inspect and modify bitfields in memory, faster evaluation of composite data structures, and better handling of Go's internal function calls during debugging.
- Delve is essential for Go developers doing low-level debugging, profiling, or crash analysis, and is tightly integrated with VS Code's Go debugger and the Go language server (gopls).
