Python bindings for NSS/NSPR allow Python programs to utilize the NSS cryptographic libraries for SSL/TLS and PKI certificate management. The python-nss package provides a Python binding to the NSS and NSPR support libraries.

Network Security Services (NSS) is a set of libraries supporting security-enabled client and server applications. Applications built with NSS can support SSL v2 and v3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12, S/MIME, X.509 v3 certificates and other security standards. NSS has received FIPS 140 validation from NIST.

Fedora includes multiple best of breed free software Java(TM) implementations, obtained through active adoption of innovative technology integrations produced by Fedora and others within upstream projects. The implementations integrated into Fedora are based on OpenJDK (http://openjdk.java.net/) and the IcedTea GNU/Linux distribution integration project (http://icedtea.classpath.org/), or based on alternatives such as the GNU Compiler for Java (GCJ - http://gcc.gnu.org/java and the GNU Classpath core class libraries (http://www.gnu.org/software/classpath/). All Fedora innovations are pushed upstream to get the widest possible integration of the technologies in general Java implementations.

The implementation of OpenJDK 6 included in Fedora 10 uses the HotSpot virtual machine runtime compiler on x86, x86_64, and SPARC. On PowerPC (PPC) it uses the zero interpreter, which is slower. On all architectures an alternative implementation based on GCJ and GNU Classpath is included that includes an ahead-of-time compiler to produce native binaries.

Fedora binaries for selected architectures (currently only x86 and x86_64 based on OpenJDK) are tested against the Java Compatibility Kit (JCK) by Red Hat to guarantee 100% compatibility with the Java Specification (JDK 1.6 at this time).

In Fedora 10 gcjwebplugin has been replaced by IcedTeaPlugin, which runs untrusted applets safely in a Web browser and works on any architecture. You can see which Applet Plugin is installed by typing about:plugins in Firefox. The new plugin adds support for the JavaScript bridge (LiveConnect) that was missing from earlier versions. For more details on the bytecode-to-JavaScript bridge (LiveConnect), refer to the bug report:

https://bugzilla.redhat.com/show_bug.cgi?id=304021

Feedback on the security policy is appreciated. If you suspect the security policy may be too restrictive to enable restricted applets, follow this procedure:

Experimental Web Start (javaws) support via NetX has been added to the IcedTea repository. When a Java Network Launching Protocol (.jnlp) file is embedded on a web page you can open it with the IcedTea Web Start (/usr/bin/javaws). For more information on NetX, refer to:

http://jnlp.sourceforge.net/

Through the IcedTea project, OpenJDK has been integrated with several new technologies that are also part of Fedora 10.

Fedora 10 includes many packages derived from the JPackage Project.

http://jpackage.org

Some of these packages are modified in Fedora to remove proprietary software dependencies, and to make use of GCJ's ahead-of-time compilation feature. Use the Fedora repositories to update these packages, or use the JPackage repository for packages not provided by Fedora. Refer to the JPackage website for more information about the project and the software it provides.

	Змішування пакетів Fedora та JPackage
	Потрібно провести дослідження на сумісність перед виконанням встановлення з обох репозиторіїв Fedora та JPackage на одній системі. Несумісність пакетів може привести до складних ситуацій.

Since Fedora 9 the packages called java-1.7.0-icedtea* in Fedora 8 have been renamed to java-1.6.0-openjdk*. The Fedora 8 IcedTea packages tracked the unstable OpenJDK 7 branch, whereas the java-1.6.0-openjdk* packages track the stable OpenJDK 6 branch. All the upstream IcedTea sources are included in the java-1.6.0-openjdk SRPM.

If you are upgrading from a system based on Fedora 8 that still has IcedTea installed, the package changeover does not happen automatically. The packages related to IcedTea based on OpenJDK 7 must first be erased, then the new OpenJDK 6 packages installed.

      su -c 'yum erase java-1.7.0-icedtea{,-plugin}' su -c 'yum install java-1.6.0-openjdk{,-plugin}'
    

Upgrading from Fedora 9 does not require special action.

This release of Fedora includes Fedora Eclipse, based on the Eclipse SDK version 3.4. The 3.4 series of releases has a "What's New in 3.4" page:

http://help.eclipse.org/stable/index.jsp?topic=/org.eclipse.platform.doc.user/whatsNew/platform_whatsnew.html

Release notes specific to 3.4 are also available.

http://www.eclipse.org/eclipse/development/readme_eclipse_3.4.html

Some of the notable features in 3.4 include a number of improvements in handling bookmarks, easier ways to find and install plug-ins, and additional help with refactoring.

Fedora 10 includes Emacs 22.2.

In addition to many bugfixes, Emacs 22.2 includes new support for the Bazaar, Mercurial, Monotone, and Git version control systems, new major modes for editing CSS, Vera, Verilog, and BibTeX style files, and improved scrolling support in Image mode.

For a detailed description of the changes see the Emacs news for the release (http://www.gnu.org/software/emacs/NEWS.22.2).

This release of Fedora has been built with GCC 4.3.2, which is included with the distribution.

Fedora 10 introduces better support for Haskell. With a new set of packaging guidelines and tools, it is incredibly easy to support any Haskell program using the Glasgow Haskell Compiler. Package creation and deployment, leveraging Fedora's quality tools plus a few new friends has never been easier. As support for Haskell grows there will be continued development for Haskell as more libraries are introduced.

Package creation is quite simple. Haskell already provides the infrastructure for compiling and deploying packages consistently. Setting up a package for Fedora takes very little time, meaning code that works in Haskell works in Fedora too.

Fedora also provides tools for enterprise deployment of Fedora packages. With the inclusion of Haskell in Fedora, the developer is now free to write enterprise level applications in Haskell and feel secure knowing the code can be used in Fedora.

Fedora 10 contains the OCaml 3.10.2 advanced programming language and a very comprehensive list of packages:

http://cocan.org/getting_started_with_ocaml_on_red_hat_and_fedora#Package_status

OCaml was available as an update to Fedora 9 but not in the initial release.

This release of Fedora includes NetBeans IDE, version 6.1. NetBeans IDE is an Integrated Development Environment (IDE) for Java, C/C++, Ruby, PHP, etc. Default configuration of the NetBeans IDE (Java SE IDE configuration) supports development of programs for the Java platform, Standard Edition (Java SE), including development of the modules for the NetBeans Platform.

The NetBeans IDE is a modular system and includes facilities for updating and installing plugins. There is a wide spectrum of plugins for the NetBeans IDE that are provided by community members and third-party companies.

The AMQP Infrastructure package is a subset of the Red Hat Enterprise MRG. The package allows for development of scalable, interoperable, and high-performance enterprise applications.

More specifically it consists of the following.

Appliances are pre-installed and pre-configured system images. This package includes tools and meta-data that make it easier for ISVs, developers, OEMS, etc. to create and deploy virtual appliances. The two components of this feature are the ACT (Appliance Creation Tool) and the AOS (The Appliance Operating System). Install the appliance-tools package with Add/Remove Software or yum.

If you need a user friendly version of the changelog, refer to http://wiki.kernelnewbies.org/LinuxChanges. A short and full diff of the kernel is available from http://kernel.org/git. The Fedora version kernel is based on the Linus tree.

Customizations made for the Fedora version are available from http://cvs.fedoraproject.org.

Fedora 10 includes the following kernel builds:

You may install kernel headers for all four kernel flavors at the same time. The files are installed in the /usr/src/kernels/<version>[-PAE|-xen|-kdump]-<arch>/ tree. Use the following command:

      su -c 'yum install kernel{,-PAE,-xen,-kdump}-devel'
    

Select one or more of these flavors, separated by commas and no spaces, as appropriate. Enter the root password when prompted.

	Ядро x86 включає Kdump
	Both the x86_64 and the i686 kernels are relocatable, so they no longer require a separate kernel for kdump capability. PPC64 still requires a separate kdump kernel.

	Kernel Includes Paravirtualization
	Both the x86_64 and the i686 kernels contain paravirt_ops support and no longer require a separate kernel for running under a Xen hypervisor. For more information, refer to Section 8.3.1, “Unified kernel image”.

	Типове ядро підтримку SMP
	У Fedora не пропонується окремого SMP ядра для архітектур i386, x86_64 та ppc64. Багатопроцесорна підтримка включена у звичайне ядро.

	Підтримка ядра для PowerPC
	There is no support for Xen or kdump for the PowerPC architecture in Fedora. 32-bit PowerPC still has a separate SMP kernel.

Fedora 10 does not include the kernel-source package provided by older versions since only the kernel-devel package is required now to build external modules. Configured sources are available, as described in Section 7.4.3, “Kernel flavors”.

	Побудова ядра зі зміненою конфігурацією

This release includes version 2.18 of avr-binutils. In addition to a large number of bugfixes, this release includes a new tool, windmc, to provide a Windows-compatible message compiler.

Version 0.4.6 of dfu-programmer is included in Fedora 10. 4k bootloaders are now supported and eeprom-flash and eeprom-dump are now supported. Release information as well as a forum specific to this version can be found at http://dfu-programmer.sourceforge.net/.

gputils has been updated to version 0.13.6 which includes support for many more PIC18 processors as well as support for Microchip's new COFF file format. Find details at http://gputils.sourceforge.net/.

Fedora 10 includes version 3.5.10 of the popular IDE piklab. This version now supports the Microchip ICD2 and PICkit in-circuit debuggers, as well as a number of other improvements. piklab now supports the following toolchains; gputils, C30 and C18, PICC, JAL, BoostC, CCS, MPC and CC5X. Many of the toolchains use Windows executables via Wine. See http://piklab.sourceforge.net/ for complete details.

Note that the executable names for sdcc have changed (see below). Since piklab does not provide for configuring executable names, but does provide for configuring paths, the piklab/sdcc user should copy files beginning with sdcc- from /usr/bin to /usr/local/bin and adjust the paths in piklab until this issue is resolved.

Windows Directory Names

Microchip has a tendency to have a lot of spaces in their default installation directories. Getting those paths configured in piklab can be quite confusing, so the dual-boot user may choose to copy files to the /usr/local tree rather than simply mounting the Windows drive and directly referencing the files in the Microchip installation. This affects not only executables, but linker scripts, headers and libraries.

Version 2.8.0 of the Small Device C Compiler is included in Fedora 10. This version offers a number of improvements to the version in Fedora 9. Some of these changes will result in changes to source code, so users should review the sdcc manual carefully for their target. In addition, due to some conflicts, all the executable names have been prefixed with sdcc-, which will require changes to makefiles. See the sdcc page at http://sdcc.sourceforge.net/ for complete details.
