Thread:Extension talk:WYSIWYG/Version of source bundles

It seems that links that refer to different source bundles of this extension have different versions. They are as follows [they all have CKEditor 3.6 (revision 6902)]...

Version of WYSIWYG Source bundles: #1 1.5.6_0 [B551]     Version of WYSIWYG_MW_v1.20.2.zip (MW 1.21.1) and WYSIWYG_MV_v1.22.0.zip (IE10, MW 1.22.0) #2 1.7.0_2_PSA        Version of http://github.com/Ciges/CKEditor_in_MediaWiki (by Ciges, MW 1.20) #3 1.7.2              Version of https://git.wikimedia.org/git/mediawiki/extensions/WYSIWYG.git (MediaWiki master) (same as https://github.com/wikimedia/mediawiki-extensions-WYSIWYG)

2 and 3 abowe are close to each other. 1 is "completely" different on some parts.

I tried to compare contents of abowe bundles but it seems to be very difficult to determine what are the diffences, because there are so many (based on contents of file). On the other hand some of the differences are such that they do not have functional effect f.ex different amount of spaces in sentences of code. Where have these kind of differences come form?

I am little confused... am I loosing something when version of extension which I am using is "1.5.6_0 [B551]"? If we modify something, what version should be used?

Modifications which I have posted here, are made in version based on bundle 1 abowe.
