TSFrames.jl provides convenient interfaces for performing standard manipulations of timeseries data.

**Why another package?**

- The package can handle heterogeneous tabular data.
- Promotes code reuse by using widely used and tested `DataFrame` at it’s core to allow powerful data manipulation functions while itself being lightweight.
- It is well tested and provides extensive documentation.
- Implements `Tables.jl` interfaces for interoperability with other packages.
- Is being actively maintained.
- Inspired by the familiar R zoo/xts API.

**Changes in this release** :

1. Added `Tables.rowcount()` method for TSFrames.
2. A new API for `join()`, including support for joining multiple TSFrames.
3. New constructors for `TSFrame` which allow creation of empty objects.
4. New convenience methods for frequency conversion (eg. `to_period()`, `to_yearly()`, etc.).
5. New API for `rollapply()`: support columnwise and table-level operations.
6. Fixed broadcasting of multiplication operator.
7. Added `Base.iterate()` method for TSFrame.
8. Add method for checking equality.
