Archived news

Here are the old news that were put here how long and painful process of development was: they don't show sleepless nights, broken expectations, false hopes, lack of beer and many other terrible things that happened.

17/04/07 MJ12node v1.4.8

A few small (but very important!) changes in this release that can be downloaded from here.

15/02/07 MJ12node v1.4.7

A small (but important!) bug fix release that can be downloaded from here.

05/02/07 MJ12node v1.4.6

A bug fix release that can be downloaded from here.

21/01/07 MJ12node v1.4.5

Big update with comprehensive support for smart recrawls of priority buckets that will keep search engine up to date, plus bug fixes, please upgrade ASAP!

30/12/06 Almost 7 bln urls added taking database to well over 30 bln!

You can see breakdown of urls by TLD here.

27/12/06 MJ12node v1.4.3

Couple more fixes to some rare but possible HTML parsing errors, please upgrade ASAP!

23/12/06 MJ12node v1.4.2

A fix to a few rare but happening during archiving errors are in this release, also updated HTMLparser to v3.0.1 with changes fixing index out of range errors in cases when HTML tag was cut midway at the end of data.

22/12/06 HTMLparser v3.0.0 + MJ12node v1.4.1

Yet another version of .NET C# HTML parser has been released with more than double improvement in performance, .NET 2.0 build, removal of dependency on unsafe code and some old incorrect parsing bugs fixed. To make it faster we used a rather novel (in parsing HTML) approach with context-sensitive heuristical prediction engine to minimise number of new strings created, this feature alone is responsible for 20% performance improvement, and complete tag parsing code rewrite add more. Heuristics engine is trained on typical HTML tagset, but you can override that or switch it off completely. If you can beat the speed of parsing with better algorithms then please let me know!

MJ12node builds updated with new fast parser, this should reduce Stage 2 archiving time very nicely, also 64-bit Vista/Longhorn now supported, get new node here.

14/12/06 MJ12node v1.4.0

Mammoth* upgrade to MJ12node is released, it is highly recommended to upgrade because new version includes a over 100 of fixes and features too numerious to list here, but inquiring minds can see the details in this forum post. This release, yet again, marks development shift back to the search engine.
* Much like poor mammoths' my will to live almost became extinct during development of this version...

04/12/06 HTMLparser v2.0.0

New version of .NET C# HTML parser has been released with about 100% improvement in performance, fixed bugs and support for text encodings to parse non-English pages correctly.

Development focus is moved to weekly search engine updates.

16/06/06 MJ12node v1.3.0

Major upgrade to MJ12node is released, it is highly recommended to upgrade because new version includes a lot of fixes and features too numerious to list here, but inquiring minds can see the details in this forum post. This release marks development shift back to the search engine itself.
