Documentation Development Tools Beat
boost gets up to speed
Fedora 18 will include Boost version 1.50. The popular collection of C libraries is updated to the newest available version with each Fedora release.
Systemtap 2.0 includes a new prototype backend, which uses DynInst to instrument a user's own binaries at runtime. This optional alternative backend does not use kernel modules, and does not require root privileges, but is restricted with respect to the kinds of probes and other constructs that a script may use.
Tracing with LTTng
Developers looking to improve their applications will find that Fedora 18's lttng-tools and ltt-ust packages provide fast and efficient tracing. The tracer allows easy correlation of userspace and kernel traces, if the latter is available. Boasting a nanosecond-precision timestamp, LTTng is especially useful when searching for ellusive latencies. Get started with the project's documentation at http://lttng.org/quickstart
Improved Crash reports
Debuginfo included by default
Fedora 18 ships with a small subset of debug information by default. Full debug information is still available in the debuginfo packages.
Debuginfo compressed by DWARF
Debuginfo will be post-processed by the DWARF compressor tool "dwz" to reduce size of the *.debug files. Developers may run this same program on their binaries.
Simplified crash reporting via ABRT Server
Fedora's bug reporting tool (ABRT) now uses new, simplified way of reporting user problems. These reports are now handled by ABRT Server, which also provides statistics and clustering of the reports, giving maintainers more accurate data about the problem.
IPython has been updated to version 0.13 and notable features and head-ups are: The Notebook has a new user interface and has many new features like auto-folding of very long lines, uploading new notebooks to the dashboard, manage started clusters and improoved tooltips. The notebook format has changed and when you want to share your notebook with users of older version, there is a conversion script available. New cell magics like %%bash, %%ruby, %%timeit and many others. The Qt console has improved menus and can directly display jpeg images.
