2018

• An update to apgsearch sets another new record by finding a 16x16 methuselah with a lifespan of 42,100 ticks.
• A self-constructing "loopship", a new type of spaceship with a non-Geminoid design, is completed by Dave Greene.
• A periodic (p5 or p4) quinti-Snark is constructed by Tanner Jacobi, with the usual implications for reductions to the glider gun collection.
• apgluxe v4.56-ll2.0.5 and Catagolue add support for BSFKL rules.
• A record-setting 39,693-tick methuselah, Wilma, is discovered by Rob Liston using a custom FPGA soup searcher.
• An new LWSS synthesis by Chris Cain allows for LWSS, MWSS, and HWSS guns with pseudo periods as low as 18. 18 is the minimum for HWSS streams.)
• Hartmut Holzwart completes a two-dimensionally extensible wick-supporting pushalong with a minimum width of over a thousand cells.
• New Orthogonoids with periods 2²⁷ and 2²⁸ are constructed by Dave Greene, followed by a 2²⁵ version by Adam P. Goucher.
• A new period-14 oscillator, 34P14.1, is found by 'carybe'.
• Christoph R. discovers a new Fireship tagalong.
• Dave Greene completes the construction of two new HashLife-friendly Demonoids.
• A complex 140-glider synthesis of a c/2 signal traveling along a diagonal long^N barge wire is completed by Martin Grant.
• A p4 bouncer reflector is constructed by Arie Paap. With the p9 reflector, this completes the set of colour-changing and colour-preserving reflectors with periods from 4 to 9.
• A p9 reflector is discovered by Matthias Merzenich and "carybe" based on Noam Elkies' bouncer reaction. This is the first reflector capable of reflecting a p27 glider stream.
• A true p33 gun is discovered by Arie Paap and Matthias Merzenich.
• A true p52 gun is completed by a collaborative effort.
• Dave Greene completes the construction of a stable line crosser with a repeat time of 501 ticks.
• The Minstrels, a group of tagalongs for Sir Robin, are discovered.
• The construction of a reverse caber-tosser shows that any glider-constructible object can be constructed with at most 35 gliders.
• A p3 reflector is discovered by Arie Paap based on Tanner Jacobi's bumper reaction. This is the first reflector capable of reflecting a p39 glider stream.
• Sir Robin, the first elementary knightship in Life, is discovered by Adam P. Goucher and Tom Rokicki.
• The 2-engine Cordership wins the 2017 Pattern of the Year competition, with Tanner's p46 taking second place.
