This plot on wikipedia was made by @RARohde based on data published in late 90s and early 00s. Wondering if this has been updated or if there is new understanding on any of these palaeo records?

Maybe @DrEvanGowan has thoughts? Anyone else?

Roger Creel's re-interpretation of Holocene records is the most significant change I'm aware of. The interpretation that mean sea level peaked in the mid-Holocene seems consistent with what is known about the history of Greenland Ice Sheet mass change, and there are now several studies suggesting a similar ice mass evolution in parts of Antarctica.
Global mean sea level likely higher than present during the holocene
@PoLaRobs @Ruth_Mottram @RARohde I am not so convinced about Meltwater Pulse 1A. There probably was a Holocene Highstand, but it was likely a GIA effect rather than the volume of ice being lower than present. I do have a new model in the works, but since no one is paying me to work on it, I don't know when it will be officially out.
@PoLaRobs @Ruth_Mottram @RARohde As for the plot itself, I don't really like it, because they combine a bunch of data from different parts of the world where the sea level history will be different. It is a bad plot.
@DrEvanGowan I see what you're saying, but if you were trying to get a constraint on how fast sea level has changed in past, it's a nice way to show it... @PoLaRobs @RARohde

Swedish and Danish Quaternary geologists and prehistoric archaeologists work continuously with an adjacent issue, shoreline displacement. It's the sum of what the land is doing after the Ice Age and what the sea level is doing. Sweden's National Geological Survey publishes an online shoreline model with 100-year resolution.
