TB: Some interesting papers I noted (I don't know how to put papers on the Gathertown tables):

https://arxiv.org/pdf/2205.04476.pdf : Olivucci, Vieira: Stampedes II: Null Polygons in Conformal Gauge Theory
https://arxiv.org/pdf/2205.05693.pdf : Basteiro, Di Giulio, Erdmenger, Karl, Meyer, Xian: Towards Explicit Discrete Holography: Aperiodic Spin Chains from Hyperbolic Tilings
https://arxiv.org/pdf/2205.09765.pdf : Barrat, Gimenez-Grau, Liendo: A dispersion relation for defect CFT
https://arxiv.org/pdf/2205.09775.pdf : Bianchi, Bonomi: Conformal dispersion relations for defects and boundaries
https://arxiv.org/pdf/2205.12969.pdf : Guo, Jin, Wang, Yang: Deciphering the Maximal Transcendentality Principle via Bootstrap

These papers look interesting to me (I have not read them yet):

Bootstrability in Defect CFT: Integrated Correlators and Sharper Bounds (Andrea Cavaglià, Nikolay Gromov, Julius Julius, Michelangelo Preti) -- https://arxiv.org/abs/2203.09556

String correlators on AdS3: analytic structure and dual CFT (Andrea Dei, Lorenz Eberhardt) – https://arxiv.org/abs/2203.13264

There are also these:

Schubert Problems, Positivity and Symbol Letters (Qinglin Yang) – https://arxiv.org/abs/2203.16112

Bootstrapping Pions at Large N (Jan Albert, Leonardo Rastelli) – https://arxiv.org/abs/2203.11950

I found this paper interesting: 2202.07627 - Large Charges on the Wilson Line in N=4 SYM: II. Quantum Fluctuations, OPE, and Spectral Curve (Giombi, Komatsu, Offertaler)

One of the last times we also had this paper on the table, but did not really discuss it:

2201.05093 - Harnessing S-Duality in N=4 SYM & Supergravity as SL(2,ℤ)-Averaged Strings (Collier, Perlmutter)

They use Laplacian spectral theory of modular invariant functions to say something about integrated correlators. I have not read it in detail, but it looks interesting. There are a couple of related papers by Dorigoni, Green, and Wen (which I have not read yet):

2102.09537 - Exact properties of an integrated correlator in N=4 SU(N) SYM

2202.05784 - Exact results for duality-covariant integrated correlators in N=4 SYM with general classical gauge groups
