The following is an overview of the history of Adam P. Goucher's Catagolue.
2015
- February 20: Catagolue becomes operative.[1]
- April 24: the B3/S23/C1 census reaches a total of one trillion objects.[2]
- September 2: the B3/S23/C1 census reaches a total of ten trillion objects.
- September 16: the pony express, the first natural infinite-growth pattern other than the block-laying switch engine and glider-producing switch engine is found in a soup.[3] After being initially rejected by Catagolue, the containing haul is recomputed and manually committed on September 28.[4]
- September 24: Catagolue supports the generation of backups, including daily backups for the C1 symmetry of Conway's Game of Life.[5]
- October 5: the first instance of Phoenix 1, the last remaining unseen 12-bit object, is found.[6]
- October 21: the B3/S23/C1 census reaches a total of twenty trillion objects.[7]
- October 27: the B3/S23/C1 census reaches a total of one trillion soups.[8]
2016
- January 25: praosylen releases a hacked version of apgsearch v0.54 which can search isotropic rules and upload the results to Catagolue.[9]
- February 20: the B3/S23/C1 census reaches a total of 50 trillion objects exactly one year after Catagolue was launched.[10]
- June 20: the B3/S23/C1 census reaches a total of 100 trillion objects.[11]
- July 5: a new period-16 oscillator, Rich's p16, is discovered in the ash of a D2_+1 soup.[12]

- August 12: a 56-bit still life, the cloverleaf interchange, is found in the B3/S23/C1 census, making it the largest still life to appear naturally.[14]
- August 22: the B3/S23/C1 census reaches a total of 100,000 distinct objects.[15]
- September 4: the B3/S23/C1 census reaches a total of 150 trillion objects.[16]
