- 01-jun-2010 Round17 revised again.
- 30-jul-2007 LongToBit10 puts an end to the dominance of LongToBit09 after almost 6 unrivaled years!
- 26-nov-2006 Base64Dec01 revised.
- 01-feb-2006 Round17 revised again.
- 13-jul-2005 Round17 revised. There was a problem with some nasty reals.

- 22-mar-2005 As a one-time exception VBspeed goes VBshort: the latest Round version is not the fastest but certainly the shortest!
- 18-mar-2005 New WordWrap hero dominates the wrapping scene.
- 14-sep-2004 The new king of endian-swapping took the throne reducing all has-beens to worthless bystanders: SwapEndian.
- 13-sep-2004 Update to the WordWrap function definition.
- 12-sep-2004 Surprised that I could not find a good, let alone fast, WordWrap function in the web, I rolled my own. The task is interesting because it can be tackled in many different ways. Here's one of them: WordWrap.
- 25-aug-2004 Note: one of our champions, Jost, discovered the hard way that InStrB returns a value that's one unit smaller than expected when String1 contains a vbNullChar at a non-first position and String2 consists of vbNullChars only. For instance, InStrB("a" & vbNullChar, vbNullChar) --> 2 instead of the expected 3. The following functions are affected by this issue and need a revision:
InStrCount02,
InStrCount04,
InStrRev06,
Replace08Bin,
Replace09Bin,
SplitA03.
- 15-aug-2004 Faster GrayScale -- if you have a Pentium processor.
- 13-aug-2004 Corrections for IsSameString01, IsSameText01, IsSameText02! They returned False when two empty strings were compared. This hideous bug survived for almost 4 years under countless pairs of peer eyes. Incredible!
- 09-aug-2004 The swapping swaps on.
- 08-aug-2004 Still alive and swapping: SwapEndian.

- 19-apr-2002 Around and around: new Round codes are good and fast. Probably the first samples where the notoriously slow Variant data type is the winner!
- 04-apr-2002 Another time the shit hits the fan: a speednik's eagle eye detected the sad truth about rounding numbers: it's a nasty business and ALL eleven codes submitted so far have been WRONG! Have a look at the one and only Round around that does it alright.

- 21-nov-2001 New kick-ass Compress champ. And it's doped.
- 21-nov-2001 Another hit at StrReverse (as if anybody would need this function...).

- 17-oct-2000 New Round code breaks thru 300 nanosecond barrier!
- 16-oct-2000 3 new Round codes added, quicker than anything we had! And we learn something about static functions: they are fast.
- 12-oct-2000 Added Same Text? to chapter Language. Wanna see something that's up to 5000 times faster than what you thought would be fast?
- 11-oct-2000 Added Same String? to chapter Language. You wouldn't believe how bad the equal operator is at string comparison!

- 25-sep-2000 Microsoft published an article HOWTO: Simulate Visual Basic 6.0 String Functions in VB5 (Last Reviewed: January 5, 2000), which features Join, Split, InStrRev, Replace, and StrReverse. The claim "This article describes how the same functionality can be used with earlier versions of Visual Basic" did not stand the test though: Microsoft's Split and Replace do not even work correctly, Join is magnitudes slower than our best Join-emulations (see yourself), and i didn't waste my time testing InStrRev and StrReverse because they are so poorly written ... it's a joke.
- 24-sep-2000 Changes in Tokenize definition and fixes in the code.
- 23-sep-2000 Added InStrCount charts, waiting for competitors ...
- 23-sep-2000 New SplitB code hits the top!
