GNU GDB 7.0 was released on October 6, 2009. Its major additions included Python scripting, reverse debugging with process record/replay, non-stop debugging, and support for debugging multiple architectures and processes. It is an archival release, not the current version: the official project page listed GDB 18.1, released September 25, 2026, as the latest release.
What was new in GDB 7.0?
The 2009 release announcement presented GDB as a source-level debugger for Ada, C, C++, Objective-C, Pascal, and other languages. It also said GDB could target more than a dozen processor architectures and run on popular GNU/Linux, Unix, and Microsoft Windows variants; those are descriptions from the 2009 announcement, not a current compatibility matrix. Read the GDB 7.0 announcement.
Python scripting and reverse debugging
GDB 7.0 added Python scripting, allowing users to extend the debugger with Python. It also introduced reverse debugging and process record/replay, which let users record program execution and move backward through recorded behavior to investigate how a problem arose.
Non-stop and multi-process debugging
The release added non-stop debugging, so a debugger could stop or resume individual threads rather than halting every thread in the process. It also expanded support for debugging multiple architectures and multiple inferiors and processes within one GDB session.

Other debugging and usability changes
The announcement also listed a GDB interface for JIT compilation, conditional tracepoints, multi-byte and wide-character support, new disassembly modifiers, automatic retrieval of shared-library files from remote targets, inlined-function support, compressed debug sections, Tru64 thread switching, Ada task switching, and a command to stop execution when a system call is made.
Which platforms and targets did the release add?
The announcement distinguished new native configurations from target support additions:
| Category | GDB 7.0 additions |
|---|---|
| Native configurations | x86/x86_64 Darwin and x86_64 MinGW |
| Targets and remote support | Lattice Mico32, x86/x86_64 DICOS, S+core 3, and an x86 Windows CE remote stub |
These are the configurations and targets named in the 2009 release announcement; they should not be read as a statement about present-day platform support.
Why was GDB 7.0 delayed?
The project schedule listed May 2009 as the planned release period and October 6, 2009 as the actual release date. Its explanation for the delay was: “Too many new features that needed a little extra time to mature.” See the GDB release schedule.

No. The official GDB page listed version 18.1, released September 25, 2026, as the latest release. The newer release’s headline changes include Windows native-target improvements such as non-stop mode on Windows 10 or later, scheduler locking, and native TLS support; those are GDB 18.1 details, not features of GDB 7.0. Check the official GDB page.
The project’s download page offers current and archived releases and notes that ancient versions go back to 1988, but warns that few are likely to work on modern hardware. For a present-day installation, start with the current release unless you specifically need GDB 7.0 for historical work or a legacy environment. Find current and archived GDB downloads.

Joel Brobecker’s 2009 announcement listed the GDB 7.0 source archives as 17 MB for gdb-7.0.tar.bz2 and 23 MB for gdb-7.0.tar.gz. Those figures describe archive sizes only; they do not indicate adoption, performance, or impact.
