Hi haskellers, As a new co-maintainer of aeson I'm happy to announce aeson 0.11.0.0[1]. v0.10 had a number of issues and v0.11 aims to fix all of these. I'm happy to see that all known regressions have been fixed, and I didn't have to write any code myself! ;) Going 0.9 to 0.11 should be no work for most users. I've built all packages in stackage nightly[2] and out of 222 only one needs a non-trivial change (sorry pagerduty maintainers!) Please help out by letting us know if we missed something, including if something should be added to the CHANGELOG[3]. A big thanks to everyone who contributed code to this release: Bryan O'Sullivan Bas van Dijk Oleg Grenrus Herbert Valerio Riedel Ben Weitzman Daniel Díaz RyanGlScott David Johnson Artyom Cale Gibbard Mikhail Glushenkov Ondrej Palkovsky Tim Bodeit mrkkrp And a thank you to everyone else who helped in other ways! All the best, Adam [1] https://hackage.haskell.org/package/aeson-0.11.0.0 [2] https://github.com/bos/aeson/issues/355 [3] https://github.com/bos/aeson/blob/master/changelog.md
