+Changed in xts 0.13.1:
+
+o Ignore attribute order in `all.equal()`. Attribute order shouldn't matter.
+  That can be checked with `identical()`.
+
+o Only call `tzone()` and `tclass()` once in `check.TZ()`. Calling these
+  functions multiple times throws multiple warnings for xts objects created
+  before the tclass and tzone were attached to the index instead of the xts
+  object. (#306)
+
+o Add instructions to update old objects. Old xts objects do not have tclass
+  and tzone attributes on the index. Add a function to update the object
+  attributes and add a note to the warning to show how to use it. (#306)
+
+o Return 'POSIXct' if object has no 'tclass'. An empty string is not a valid
+  'tclass', so it can cause an error.
+
+o Add notes on `plot.xts()` nomenclature and structure. Also add ASCII art to
+  illustrate definitions and layout. (#103)
+
+o Remove 'tis' support. The implementation was not even a bare minimum, and
+  it's not clear it even worked correctly. (#398)
+
+o Register missing S3 methods and update signatures. With R-devel (83995-ish),
+  `R CMD check` notes these S3 methods are not registered. It also notes that
+  the signatures for `as.POSIXct.tis()` and `str.replot_xts()` do not match
+  the respective generics.
+
+  It also thinks `time.frequency()` is a S3 method because `time()` is a
+  generic. The function isn't exported, so renaming won't break any external
+  code. Thanks to Kurt Hornik for the report. (#398)
+
+o Format each column individually before printing. The top/bottom rows could
+  have a different number of decimal places and there are often multiple
+  variying spaces between columns. For example:
+
+                                close      volume          ma         bsi
+      2022-01-03 09:31:00     476.470  803961.000          NA   54191.000
+      2022-01-03 09:32:00     476.700  179476.000          NA   53444.791
+      2022-01-03 09:33:00     476.540  197919.000          NA  -16334.994
+                      ...
+      2023-03-16 14:52:00    394.6000  46728.0000    392.8636  28319.4691
+      2023-03-16 14:53:00    394.6500  64648.0000    392.8755  15137.6857
+      2023-03-16 14:54:00    394.6500  69900.0000    392.8873  -1167.9368
+
+  There are 4 spaces between the index and the 'close' column, 2 between
+  'close' and 'volume', 4 between 'volume' and 'ma', and 2 between 'ma' and
+  'bsi'. There should be a consistent number of spaces between the columns. Most
+  other classes of objects print with 1 space between the columns.
+
+  The top rows have 3 decimals and the bottom rows have 4. These should also be
+  the same. (#321)
+
+o Only convert printed index values to character. Converting the entire index
+  to character is time-consuming for xts objects with many observations. It can
+  take more than a second to print an xts object with 1mm observations.
+
+o Make column names based on number of columns. The original code was a lot
+  more complicated because it tried to account for truncating the number of
+  printed columns. That functionality was removed because of how complicated
+  it was. So now we can simply create printed column names from the number of
+  columns. (#395)
+
+o Fix `xts()` for zero-row data.frame. The `xts()` constructor would create an
+  object with a list for coredata when 'x' is a data.frame with no rows. It
+  needs to convert 'x' to a matrix and throw an error if 'x' is a list. (#394)
+
+o Reduce instances when `dplyr::lag()` warning is shown. The warning was shown
+  whenever it detected dplyr is installed, even if the user wasn't actively
+  using dplyr. That caused an excessive amount of noise when other packages
+  attached xts (e.g. quantmod). Thanks to Duncan Murdoch for the report and
+  suggested fix! (#393)
+
+o Keep colname when only one non-time-based column. The subset `x[, -which.col]`
+  would return a vector when the data frame has a time-based column and only
+  one additional column. Do not drop dimensions, so 'x' will still be a
+  data.frame in this case. (#391)
+
+o Treat NA the same as NULL for start or end values. NULL represents an
+  undefined index value. NA represents an unknown or missing index value. xts
+  does not allow NA as index values. Subsetting an xts or zoo object by NA
+  returns a zero-length object. So a NA (unknown) index value is essentially
+  the same as an undefined index value. (#383, #345)
+
+o Warn and remove NA when `periodicity()` called on date-time with NA.
+  Otherwise the uninformative error below will be thrown. (#289)
+
+      Error in try.xts(x, error = "'x' needs to be timeBased or xtsible") :
+        'x' needs to be timeBased or xtsible
+
+o Account for TZ when making names for `split.xts()`. `as.yearmon.POSIXct()`
+  always sets `tz = "GMT"` when calling `as.POSIXlt()`, regardless of the xts'
+  index tzone.  That can cause the `as.yearmon()` results to be different days
+  for GMT and the index's timezone.
+
+  Use `format.POSIXct()` for "months" because it checks for a 'tzone' attribute
+  before converting to POSIXlt and calling `format.POSIXlt()`.  The conversion
+  to POSIXlt is important because it checks and uses the 'tzone' attribute
+  before considering the 'tz' argument. So it effectively ignores the
+  `tz = "GMT"` setting in `as.yearmon()`. This is also the reason for calling
+  `as.POSIXlt()` before calling `as.yearqtr()`. (#392)
