OS/2 is a series of computer operating systems, initially created by Microsoft and IBM under the leadership of IBM software designer Ed Iacobucci. As a result of a feud between the two companies over how to position OS/2 relative to Microsoft's new Windows 3.1 operating environment, the two companies severed the relationship in 1992 and OS/2 development fell to IBM exclusively. The name stands for 'Operating System/2. I'm relatively new in Mac OS. I've just installed XCode (for c compiler) and Anaconda with the latest Python 3 (for myself). Now I'm wondering how to install properly second Anaconda (for work) with Python 2? I need both versions to work with iPython and Spyder IDE. Ideal way is to have totally separate Python environments.

Release Date: April 10, 2012

Note: A newer security-fix release, 3.2.6, is currently available. Its use is recommended.

Python 3.2.3 was released on April 10, 2012. It includes fixes for severalreported security issues: issue 13703 (CVE-2012-1150, hash collision denialof service), issue 14234 (CVE-2012-0876, Expat hash collision denial ofservice), issue 14001 (CVE-2012-0845, SimpleXMLRPCServer denial of service),and issue 13885 (CVE-2011-3389, disabling of the CBC IV attack countermeasurein the _ssl module).

Python 3.2 is a continuation of the efforts to improve and stabilize the Python3.x line. Since the final release of Python 2.7, the 2.x line will only receivebugfixes, and new features are developed for 3.x only.

Since PEP 3003, the Moratorium on Language Changes, is in effect, there areno changes in Python's syntax and only few changes to built-in types in Python3.2. Development efforts concentrated on the standard library and support forporting code to Python 3. Highlights are:

• numerous improvements to the unittest module
• PEP 3147, support for .pyc repository directories
• PEP 3149, support for version tagged dynamic libraries
• PEP 3148, a new futures library for concurrent programming
• PEP 384, a stable ABI for extension modules
• PEP 391, dictionary-based logging configuration
• an overhauled GIL implementation that reduces contention
• an extended email package that handles bytes messages
• a much improved ssl module with support for SSL contexts and certificatehostname matching
• a sysconfig module to access configuration information
• additions to the shutil module, among them archive file support
• many enhancements to configparser, among them mapping protocol support
• improvements to pdb, the Python debugger
• countless fixes regarding bytes/string issues; among them full supportfor a bytes environment (filenames, environment variables)
• many consistency and behavior fixes for numeric operations

In case one of the links above does not work, try this mirror. If the download is too slow try some other mirror closer to you.

2.2 Mac OS X binaries

LyX for Mac OS X is available here: LyX-2.3.6.2+qt5-12-x86_64-cocoa.dmg, and the GPG signature is here.

Binaries for older versions of Mac OS X are available here: LyX-2.3.6.2+qt5-legacy-x86_64-cocoa.dmg, and the GPG signature is here. Some functionality is not available with these (e.g., SyncTeX).

Before you install LyX you need to install a TeX system such as MacTeX.

In case the links above do not work, try this mirror. If the download is too slow try some other mirror closer to you.

On Mac OS X Mountain Lion you'll get the error message:'LyX' can't be opened because it is from an unidentified developer. See the explanation here for a work around.

See the LyX/Mac wiki page for further installation tips.

2.3 Linux binaries

Major Linux distributions take care of LyX binaries themselves and you will find LyX in their repositories. For more details about your distribution look in our wiki.

For Ubuntu users, Liviu Andronic maintains a stable PPA (Personal Package Archive). See the LyX on Ubuntu wiki page for information and instructions.

The versions of LyX on a variety of Linux distributions (as shipped with the vanilla distribution) can be seen on the snippet below. We usually choose testing/unstable repositories. For more detailed listing go here.

2.4 OS/2 binaries

LyX has unofficial ports to OS/2, binaries are here (LyX 2.0.7).

2.5 Haiku binaries

LyX has unofficial ports to Haiku, packages (2.1.x,2.0.0,2.2.3,2.3.4) can be found in Haiku package repositories.

3. Additional Software

If you're not using one of the installers or packages, you may need to install some additional software.

4. Version numbers

There are certain rules how the LyX version numbers are assigned. Read the following page for detailed information.

6. Mirrors

Please use one of the ftp mirrors below in case our default server (located in France) is slow or unavailable. Both ftp://ftp.lyx.org and https://ftp.lip6.fr/ point to the same primary server, but unless you actively check the signatures of downloaded files, you better use https protocol.

Note that we don't have any direct control over the content in the mirrors, so you are well advised to check signatures of the downloaded files to make sure they are identical to those on the primary site.

• Εθνικό Μετσόβιο Πολυτεχνείο(ftp) (Greece)
• GARR (Italy)
• Uniwersytet Warszawski(ftp) (Poland)
• Макомнет(ftp) (Russia)
• دانشگاه صنعتی اصفهان (Iran)
• Universiteit van die Vrystaat(ftp) (South Africa)
• Universidade de Brasília(ftp) (Brazil)
• Universidad de Chile (Chile)
• CEDIA (Ecuador)
• Universidad de la República (Uruguay)
• 清华大学开源软件镜像站 (China)
• KDDI総合研究所(ftp) (Japan)
• 山形大学(ftp) (Japan)
• 한국과학기술원(ftp) (Korea)
• AARnet (Australia)
• MUUG(ftp) (Canada)
• ibiblio(ftp) (USA)
• University of Utah (USA)
• UCSD (USA)

7. Checksums & signing

We provide gpg-signed tarballs and binaries. That allows you to check integrity of downloaded package and provides guaranty that no one tampered with the binary on the ftp server or on the way to your computer. Our GPG key ID is 0xDE7A44FAC7FB382D (LyX Release Manager). The signatures are found next to the tarballs and binaries.

• To initially import our key via GnuPG, do this:gpg --recv-keys FE66471B43559707AFDAD955DE7A44FAC7FB382D

Attention: Please be careful to use this full fingerprint, spoofed version of shortened fingerprint is already in the wild and it is easy to make new fake ones!

See Full List On Support.apple.com

• After that, each time you need to verify a tarball:gpg --verify lyx-2.3.6.tar.gz.sig

to check the signature (or any other signed file you want to verify). Watch out for the 'Good signature...' string.
