* '''Apr. 21''': [http://conwaylife.com/forums/viewtopic.php?p=75278#p75278 Improvements to glider syntheses] mean that every 15-bit still life has a recipe with at most 13 gliders. The upper limit is currently 12 gliders for 14-bit still lifes, 10 gliders for 13 bits, 8 gliders for 12 bits, and 7 gliders for 11 bits.

* '''Mar. 24''': [[apgsearch]] v5.03 gains the ability to log 'megasized' [[soup]]s with final [[population]]s exceeding 3,000.[https://gitlab.com/apgoucher/apgmera/commit/2133cb40147cbb7b70f1a5fb4709f8f3b2feb6f7] [[Apgsearch#Version_5.x|apgsearch 5.x]] can also pre-process asymmetric C1 B3/S23 soups on GPUs with CUDA support.[http://conwaylife.com/forums/viewtopic.php?p=73557#p73557]

* '''Mar. 3''': A [[figure eight on pentadecathlon|period-120 oscillator]], the highest period thus far, occurs from a natural [[soup]] on [[Catagolue]].
 +
* '''Mar. 2''': Several symmetric-soup [[diehard]]s with [https://catagolue.appspot.com/object/messless_15h/b3s23 lifespans over 1500 ticks] have been found by 'carybe', using [[apgsearch]].

* '''Feb. 12''': A [[lightweight Schick engine]] appears from a natural (C1) [[soup]] on [[Catagolue]].
 +
* '''Feb. 9''': A [[47575M|47,575-tick 16x16 methuselah]] found by Adam Goucher via [[apgsearch]] yields a 16-cell, 47,487-tick methuselah. This discovery skips over several empty 1000-tick bins in [[Catagolue]] above the previous record 16x16 methuselah, [[Homer]].

 +
* '''Feb. 4''': [[Tanner Jacobi]] and [[Martin Grant]] [http://www.conwaylife.com/forums/viewtopic.php?p=69591#p69591 find a recipe], subsequently reduced to 88 gliders, for the first-ever synthesizable [[c/4]] spaceship, [[46P4H1V0]].
 +
* '''Jan. 21 - Feb. 1''': Additional (2,1)c/6 [[minstrel]]s and spaceship connections are found, bringing the number of combinations of elementary minstrels into double digits.
