+## PuTTY
+
+For decades, PuTTY has been the go-to tool for professional Windows users 
+creating SSH connections. PuTTY was first released in 1999 by Simon Tatham
+and has resisted the taboo of nonzero major versions for over 25 years.
+PuTTY's journey has been nothing short of legendary.
+
+Much like the tool itself, PuTTY's versioning approach is efficient,
+lightweight, robust, and focused on functionality rather than marketing optics
+like major releases. Even as the SSH protocol itself revved from version 1 to 2,
+PuTTY remained steadfast under the reassuring banner of 0.x.
+
+PuTTY's commitment to ZeroVer reminds us that great software doesn't need major
+version numbers to make a major impact.
