0.10.0

  • add support for time series plotting via RecipesBase dependency (thank you @mkborregaard)
  • add StepRange indexing support (issue #311)

0.9.2

  • improve readtimearray to accept IOBuffer (@femtotrader fixes issue #298)

0.9.1

  • improve update method and dis-allow updating of empty time arrays (fixes issue #286)

0.9.0

  • first version to support julia 0.5 release candidates

0.8.8

  • merge method deals with meta field values more robustly (fixes issue #164)

0.8.7

  • reexport Base.Dates methods and DataTypes (fixes issue #277)

0.8.6

  • unique column names are enforced (fixes issue #255)

0.8.5

  • update() method creates new TimeArray from existing one, with new timestamp/value pair.
  • rename() method creates new TimeArray from existing one, with new column name(s).
  • adds tail() and head() methods

0.8.4

  • allows users to show customizable representations for missing values, which are represented as NaN values in the array.

0.8.3

  • provides TimeArray constructor without requiring colnames argument (defaults to empty array)

0.8.2

  • makes to() and from() more robust by taking zero-length time arrays (@dourouc05 )

0.8.1

  • removes using Base.Dates from outside module @tkelman

0.8.0

  • deprecated collapse(ta::TimeArray, f::Function; period::Function=week) in favour of collapse(ta::TimeArray, period::Function, timestamp::Function, value::Function=timestamp) and added support for collapsing 2D TimeArrays

0.7.4

  • allow math operations between different Number subtypes
  • explicitly convert column names to strings in readtimearray
  • operations between TimeArrays with non-matching meta fields now succeed, with a Void meta in the result

0.7.3

  • ensure dates are sorted for vcat and map (@dourouc05)

0.7.2

  • map and vcat methods added (thanks again @dourouc05)

0.7.1

  • readtimearray method now allows arbitrary delimiters (thanks @dourouc05)

0.7.0

  • TimeType replaces Union{Date, DateTime}
  • meta field in Type downgraded from parameterized to Any
  • NaN sentinels added as a kwarg to lag and lead methods
  • merge method now supports left, right and outer joins
  • percentchange takes method argument as a Symbol vs String
  • new methods added including: uniformspaced, uniformspace, dropnan, diff
  • findall added to deprecated list in favor of find

0.6.7

  • refactors when() method for 30% performance improvement

0.6.6

  • begin deprecation of by() method, which is being replaced by when()
  • when() re-arranges the argument order to TimeArray, Function, Int (or ASCIIString)
  • support for ASCIIStrings are now provided for both by() and when() methods

0.6.5

  • support added for displaying empty TimeArray
  • common scalar -> scalar math functions as unary operators
  • adds isnan and isinf
  • fixes tests on meta field
  • downgrades show tests to pending

0.6.4

  • replaces Nothing -> nothing and String -> AbstractString

0.6.3

  • precompile support added
  • test/combine.jl and test/split.jl now imports Base.Dates explicity

0.6.2

  • added support for end keyword in indices
  • added support for lookups via Boolean TimeArrays - e.g. ta[ta["col"] .> 50]
  • speedup for lookups via lists of Date/DateTime objects

0.6.1

  • a phantom release that is actually older than 0.6.0

0.6.0

  • first version with support for Julia 0.4 only
  • generalized value container from Array to AbstractArray
  • implemented new element-wise operators: !, ~, &, |, $, %, !==
  • implemented element-wise unary math operators (+, -)
  • side note: a previous commit was tagged with v0.6.0 incorrectly, this commit resolves that mistake

0.5.11

  • last version with support for Julia 0.3
  • support for Julia 0.4 dropped, along with the Compat package

0.5.10

  • changed references of flipud(A) to flipdim(A,1)_
  • changed references of round(x) to iround(Integer,x)_
  • changed references of iround(Integer,x) back to round(Integer,x)_
  • changed references of int(x) to round(Int64, x)
  • changed references of float(x) to map(Float64, x)
  • changed references of [a] to [a;] in a comprehension found in the by() method
  • added Compat package
  • substantial speedup for element-wise mathematical operators

0.5.9

  • added kwarg argument format to the readtimearray method to allow parsing datetime formats that are not currently supported.
  • changed two references to Range1 to UnitRange
  • added import of Base.values. I had defined it first and I guess they like it so much they co-opted it. :)

pre-0.5.8

Not currently documented.
