The following is an overview of the history of Adam P. Goucher's Catagolue.

2015

  • February 20: Catagolue becomes operative.
  • April 24: the B3/S23/C1 census reaches a total of one trillion objects.
  • 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.[1] After being initially rejected by Catagolue, the containing haul is recomputed and manually committed on September 28.[2]
  • September 24: Catagolue supports the generation of backups, including daily backups for the C1 symmetry of Conway's Game of Life.
  • October 5: the first instance of Phoenix 1, the last remaining unseen 12-bit object, is found.[3]
  • October 21: the B3/S23/C1 census reaches a total of twenty trillion objects.

2016

  • January 25: Aidan F. Pierce releases a hacked version of apgsearch v0.54 which can search isotropic non-totalistic Life-like cellular automata rules and upload the results to Catagolue.[4]
  • February 20: the B3/S23/C1 census reaches a total of 50 trillion objects exactly one year after Catagolue was launched.
  • June 20: the B3/S23/C1 census reaches a total of 100 trillion objects.
  • July 5: a new period-16 oscillator, Rich's p16, is discovered in the ash of a D2_+1 soup.
  • July 6: the B3/S23/C1 census reaches a total of 5 trillion soups.
  • August 22: the B3/S23/C1 census reaches a total of 100,000 distinct objects.
  • September 4: the B3/S23/C1 census reaches a total of 150 trillion objects.
  • September 20: D2_+2 becomes the first B3/S23 symmetry other than C1 to reach 1 trillion objects.

2017

  • January 13: Catagolue starts collecting slow salvo data using the SS pseudo-symmetry.
  • March 15: B38/S23/C1 (Pedestrian Life) becomes the first rule/symmetry other than B3/S23/C1 to reach 10 trillion objects.
  • May 16: the B3/S23/C1 census reaches a total of 200 trillion objects.
  • August 19: Catagolue gains the ability to census Generations and B0 rules, fed by apgsearch 4.0.[5]
  • August 21: Catagolue gains the ability to census Larger than Life rules, fed by apgsearch 4.1.[6]
  • September 10: Catagolue gains official support for isotropic non-totalistic rules, fed by apgsearch 4.2.[7] Previously, these rules required a hacked version of the original apgsearch Golly script.

2018

2019

  • January 3: the B3/S23/C1 census reaches a total of 300 trillion objects.
  • January 9: Catagolue gains the ability to census Golly rule tables and rule trees, fed by apgsearch 4.8.
  • January 15: Catagolue gains native support for Deficient and Extended Generations rules, fed by apgsearch 4.83.
  • February 12: a Schick engine first appears naturally in an asymmetric soup.[14]
  • March 3: a figure eight on pentadecathlon first appears in an asymmetric soup,[15] making it the highest period oscillator to have occurred naturally.[16]
  • March 24: Catagolue starts collecting data on soups with large final populations, fed by apgsearch 5.03.[17]
  • March 27: the first instance of long^4 melusine, the last remaining unseen 14-bit still life, is found.[18]
  • March 31: the B3/S23/C1 census reaches a total of one million submitted hauls.
  • April 12: Catagolue starts collecting data about glider syntheses from Jeremy Tan's Shinjuku database.
  • April 14: the B3/S23/C1 census reaches a total of 400 trillion objects.
