Adobe's PDF specifications
Adobe changed the PDF specification several times and continues to develop new specifications with new versions of Adobe Acrobat. There have been nine versions of PDF with corresponding Acrobat releases:
* (1993) – PDF 1.0 / Acrobat 1.0
* (1994) – PDF 1.1 / Acrobat 2.0
* (1996) – PDF 1.2 / Acrobat 3.0
* (1999) – PDF 1.3 / Acrobat 4.0
* (2001) – PDF 1.4 / Acrobat 5.0
* (2003) – PDF 1.5 / Acrobat 6.0
* (2005) – PDF 1.6 / Acrobat 7.0
* (2006) – PDF 1.7 / Acrobat 8.0
* (2008) – PDF 1.7, Adobe Extension Level 3 / Acrobat 9.0
* (2009) – PDF 1.7, Adobe Extension Level 5 / Acrobat 9.1
The ISO standard ISO 32000-1:2008 is equivalent to Adobe's PDF 1.7.
Adobe declared that it is not producing a PDF 1.8 Reference.
PDF 2.0
A new version of PDF standard is under development under the name ISO/NP 32000-2 - Document management—Portable document format—Part 2: PDF 2.0 (as of January 2011). Adobe has submitted the Adobe Extension Level 5 and Adobe Extension Level 3 specifications to ISO for inclusion into the next version of the ISO 32000 specification. Adobe declared they have all been accepted for part 2 of ISO 32000

, I give a
to Foxit PDF Editor 2.2, and I expect I will end up forking out that $99 (after I've tested compatibility with a few more PDFs).I had tried PDFEDIT (GPL'd software) under Linux, but it was quite buggy and the user interface was horrible.I've used it a bit for minor edits. I've been lucky enough to not hit any bugs so far, but agree that the UI is less than stellar.
I was looking for a PDF editor .... So I downloaded ... Foxit PDF Editor 2.2
The non-crippled version has a purchase price of $99.
PagePlus X6 also makes for a killer PDF editor, with functions that include the ability to open, edit, and save PDFs, share PDF forms, and more.
Full PDF editing and broad compatibility
Fully edit PDFs from anywhere, with more flexibility than any other desktop publishing software – ideal for updating and refreshing existing documents or correcting errors in PDFs before they are distributed or printed. Full PDF editing power lets you move, resize, recolour, replace anything in the design, add new text and images, include bookmarks and notes, merge multiple PDFs, manage pages, and add security. It’s like editing a normal PagePlus file – there is nothing you can’t do!
Editing PDFs is easy with PagePlus X6 (see video)
