  • All the index-attributes have been removed from the xts object and are now only attached to the index itself (#245). We took great care to maintain backward compatibility, and throw warnings when deprecated functions are called and when index-attributes are found on the xts object. But there still may be some breaking changes lurking in edge cases.

  • @SamoPP found one edge case (#297) where an error was thrown when index() was called on an xts object with an index that had no tclass attribute.

  • ...which led Joshua to find that the index setting functions did not always copy index attributes (#305).

  • Several binary operations (e.g. +, -, !=, <, etc.) on variations of uncommon xts objects with other xts, matrix, or vector objects, could result in malformed xts objects (#295). Some examples of the types of uncommon xts objects: no dim attribute, zero-width, zero-length.

  • Calling as.matrix() on an xts object without a dim attribute no longer throws an error (#294).

  • merge.xts() now honors check.names = FALSE (#293).

  • The possible values for major.ticks, minor.ticks, and grid.ticks.on in the Details section of ?plot.xts have been corrected. Thanks to Harvey Smith (@harvey131) for the report and patch (#291).

  • as.zoo.xts() is now only registered for zoo versions prior to 1.8-5. Methods to convert an object to another class should reside in the package that implements the target class. Thanks to Kurt Hornik for the report (#287).

  • .parseISO8601() no longer has a potential length-1 logical error. Thanks to Kurt Hornik for the report (#280).

  • endpoints() now honors k > 0 when on = "quarters". Thanks to @alkment for the report (#279).

  • Performance for the period.XYZ() functions (sum, prod, min, max) is much faster (#278). Thanks to Harvey Smith (@harvey131) for the report and examples.

  • merge.xts() now creates shorter column names when passed unnamed objects. This is now consistent with zoo (#248).

  • Time-of-day performance is ~200x faster, thanks to StackOverflow user3226167 (#193).
