What is new in Pajek 5.01?

Feb 1, 17 Pajek 5.01: Another version of Pajek proposed for analysis of huge networks - Pajek3XL - is now available. The highest number of vertices that Pajek64-3XL can handle is ten billion (9.999.999.997). Details.
Jan 17, 17 Files read recently (e.g. networks, partitions, ini files,...) are now added as items to File menu. In this way files can be read by Pajek without exploring hard drives.
Dec 26, 16 Bug when reading GEDCOM files as p-graphs fixed.
Nov 15, 16 Bug when tabulators were used instead of spaces in input file - vertices with shapes different from ellipses were not drawn correctly in Draw window.
Aug 15, 16 Maximum number of networks in SVG sequence increased to 9999 (exporting to SVG with Export / SVG / Current and all Subsequent checked).
July 26, 16 Appending networks to project file to be later used by PajekToSVGAnim (Export / Append to Pajek Project File) is now recorded to log files as well. That means that Macro / Repeat Last Command can be used - sequence of networks can be appended to PAJ file with a single click.
July 15, 16 Pajek adapted to and recompiled with the latest version of Delphi and MtxVec.
May 14, 16 In addition to extracted SubNetwork, corresponding Partition and/or Vector can be sent from PajekXXL directly to Pajek too.
May 13, 16 Sending Network from PajekXXL to Pajek is now the first item in Tools menu (it is not an option in Network menu anymore).
May 10, 16 Pajek 4.10: ...Complete history since November 15, 1996...
