boost provides a set of portable, peer-reviewed, C++ libraries. In Fedora 15, Boost is brought up to date with the current upstream, version 1.4.6.
With every new release of Boost come new components and libraries. For instance, Boost 1.46 brings ICL, and Boost 1.45 had already brought MSM and Polygon.
Moreover, the existing components and libraries are enhanced with new features and bug fixes. For instance, the Boost.Math components have now become better than the GSL for support to statistical analysis.
For full details, see the Boost pages at http://www.boost.org/
erlang and the associated packages have been updated to R14B. This release contains a number of performance improvements, especially around threads, as well as a number of bug fixes. More details may be found in the readme.
This new GDB release 7.3 together with Archer and Fedora extensions improves debugging experience on Fedora by making the debugger more powerful. The majority of these features were written by Red Hat engineers, thus benefiting all gdb users. New features for the Fedora 15 release are not limited to:
- Support for breakpoints at SystemTap markers (probes)
- Support for using labels in the program's source
- OpenCL language debugging support
- Thread debugging of core dumps - priting
pthread_tof threads and their TLS variables
- Python scripting improvements not limited to:
- GDB values in Python are now callable if the value represents a function address.
- New module gdb.types for inferior types.
- New module gdb.printing for writing and registering pretty-printers.
More features are listed upstream above the line
*** Changes in GDB 7.2.
Numerous important packages within Fedora are pre-built with SystemTap static markers, and these can now be used as the target for breakpoints in gdb.
mono has been updated to 2.8.1. The 2.8 release of Mono contains a large number of new features including:
- C# 4.1
- New garbage collector
- New frameworks from Mono MIT X11 and Microsoft MS-PL/Apache2
- Performance improvements
For compete dtails refer to the release notes at http://www.mono-project.com/news/
Fedora 15 includes OCaml 3.12, a major new release of the OCaml language, the camlp4 macro language, libraries, and CDuce for XML processing.
New language features include:
- modules are now first-class values
- nested module open
- open record notation
- mark OO methods which must be overridden in subclasses
- limited support for delimited overloading in the language
camlp4 and camlp5 macro languages have been revised and extended. The changes are completely backwards compatible. For all details refer to https://fedoraproject.org/wiki/Features/OCaml3.12
The Python 3 stack in Fedora 15 updates from 3.1 to 3.2 (the system Python 2 stack remains at 2.7). Python 3.2 is the latest release of the Python 3 language which comes with hundreds of fixes and tweaks throughout. For all details refer to https://fedoraproject.org/wiki/Features/Python_3.2.
The Ruby on Rails gems in Fedora 15 updates from 2.3.8 to 3.0.3. Rails 3 is a large update to the Ruby on Rails web framework. It brings many new features such as a polished routing API, new activemailer and activerecord APIs, and many more new enhancements. Since its a major version update there are some API incompatibilities between Rails 3 and Rails 2.3.8. For the details refer to https://fedoraproject.org/wiki/Features/Rails_3.0.3.
Tryton, a three-tier general purpose application platform and basis for a ERP system, is available in Fedora 15.
The core of Tryton (also called Tryton kernel) provides all the necessary functionalities for a complete application framework: data persistence, extensive modularity, users management (authentication, fine grained control for data access, handling of concurrent access of resources), workflow and report engines, web services and internationalisation. Thus constituting a complete application platform which can be used for any relevant purpose. Base Modules
Currently, the main modules available for Tryton cover the following fields of activity:
- Sale Management
- Purchase Management
- Analytic Accounting
- Inventory Management
