 ## POTENTIALLY BREAKING CHANGES
 
 1. In v1.13.0 (July 2020) native parsing of datetime was added to `fread` by Michael Chirico which dramatically improved performance. Before then datetime was read as type character by default which was slow. Since v1.13.0, UTC-marked datetime (e.g. `2020-07-24T10:11:12.134Z` where the final `Z` is present) has been read automatically as POSIXct and quickly. We provided the migration option `datatable.old.fread.datetime.character` to revert to the previous slow character behavior. We also added the `tz=` argument to control unmarked datetime; i.e. where the `Z` (or equivalent UTC postfix) is missing in the data. The default `tz=""` reads unmarked datetime as character as before, slowly. We gave you the ability to set `tz="UTC"` to turn on the new behavior and read unmarked datetime as UTC, quickly. R sessions that are running in UTC by setting the TZ environment variable, as is good practice and common in production, have also been reading unmarked datetime as UTC since v1.13.0, much faster. Note 1 of v1.13.0 (below in this file) ended `In addition to convenience, fread is now significantly faster in the presence of dates, UTC-marked datetimes, and unmarked datetime when tz="UTC" is provided.`.
 
-    At `rstudio::global(2021)`, Neal Richardson, Director of Engineering at Ursa Labs, compared Arrow CSV performance to `data.table` CSV performance, [Bigger Data With Ease Using Apache Arrow](https://twitter.com/enpiar/status/1357729619420475392). He opened by comparing to `data.table` as his main point. Arrow was presented as 3 times faster than `data.table`. He talked at length about this result. However, no reproducible code was provided and we were not contacted in advance in case we had any comments. He mentioned New York Taxi data in his talk which is a dataset known to us as containing unmarked datetime. [Rebuttal](https://twitter.com/MattDowle/status/1360073970498875394).

     `tz=`'s default is now changed from `""` to `"UTC"`. If you have been using `tz=` explicitly then there should be no change. The change to read UTC-marked datetime as POSIXct rather than character already happened in v1.13.0. The change now is that unmarked datetimes are now read as UTC too by default without needing to set `tz="UTC"`. None of the 1,017 CRAN packages directly using `data.table` are affected. As before, the migration option `datatable.old.fread.datetime.character` can still be set to TRUE to revert to the old character behavior. This migration option is temporary and will be removed in the near future.
