| 1984 | Greuel/Pfister: Do there exist complete intersection singularities   which are not quasi-homogeneous but whose Poincare-complex is exact? | 
| 1987 | Pfister et al (Humboldt Uni Berlin): Developed package Buchmora for Atari in   Modula-2 to verify existence. 
 | 
| 1989 | Buchmora is renamed to Singular. Jointly developed by groups from Berlin (Pfister) and Kaiserslautern (Greuel). | 
| 1990 | Ported to Unix; First user manual released. | 
| 1993 | Rewritten in C; Singular programming language - Libraries established. | 
| 1996 | Multivariate polynomial factorization and gcd implemented. | 
| 1997 | Singular release 1.0 (with multivariate polynomial factorization,   gcd, syzygies, resolutions, and communication links). | 
| 1998 | Singular release 1.2 (faster with primary decomposition and normalization). | 
| 1999 | Singular release 1.4   (even faster, with numerical data types and algorithms,   monodromy, moduli of space curves, and debugger). | 
| 2001 | Singular release 2.0 | 
| 2002 | Textbook  "A 	  Singular Introduction to Commutative Algebra" published by Springer Verlag (including a CD containing a 	distribution of Singular version 2.0.3). | 
| 2004 | The Singular team was awarded the Richard D. Jenks Memorial Prize for Excellence in 	Software Engineering for Computer Algebra. | 
| 2005 | Textbook "Computing in Algebraic Geometry: A Quick Start using Singular" published by Springer Verlag | 
| 2005 | Singular release 3.0 (with dynamic modules, name spaces, noncommutative 	computations, resolution of singularities, absolute 	factorization, etc.) | 
| 2007 | Second edition of the textbook  "A 	  Singular Introduction to Commutative Algebra" published by Springer Verlag (including a CD containing a 	distribution of Singular version 3.0.3). |
