• [NEW]: Support TA-Lib C 0.8.1, which is now the minimum required version.

• [NEW]: The 40 functions TA-Lib C added since 0.7.1: AC, ADR, AO, CMF, CMOU, COPPOCK, CUMSUM, CVI, DONCHIAN, DPO, EFI, ER, ERI, FOSC, FRACTAL, HA, HMA, KC, KDJ, MARKETFI, MASSI, NVI, PERCENTILE, PERCENTRANK, PVI, PVO, PVT, QSTICK, RMA, RVI, RVOL, SMI, SUPERTREND, TSI, VHF, VORTEX, VWAP, VWMA, WAD, ZLEMA.

• [NEW]: New moving averages: MA_Type.HMA, MA_Type.DISABLED, MA_Type.DEFAULT, MA_Type.ZLEMA and MA_Type.RMA.

• [NEW]: set_unstable_period() and get_unstable_period() accept 'RMA', 'HA' and 'RVI'.

• [FIX]: abstract raised KeyError on function and output flags added after this wrapper was written; unknown flag bits are now ignored.

• [FIX]: A moving-average parameter not spelled exactly matype -- KDJ's slowk_matype -- defaulted to SMA rather than to the function's own documented default.

• [FIX]: An integer output is documented as the candlestick -100/0/100 convention only for candlestick functions; SUPERTREND's is a trend direction.

• [CHANGE]: APO and PPO now default matype to EMA, and BBANDS defaults timeperiod to 20, following TA-Lib C 0.8.1.

• [FIX]: set_unstable_period() targeted the wrong function for every id after IMI (e.g. 'RSI' set PLUS_DM); ids now come from the C header. 'ADXR', 'MFI' and 'STOCHRSI' are no-ops that emit a DeprecationWarning.

• [FIX]: Improve docstrings for indicators in talib.func.

• [FIX]: Initialize and shutdown underlying TA-Lib only once each process. This should give slight speedups when using many indicators (<5%).

• [DEPRECATED]: The old moving average types that were in talib.func are now deprecated. See the next bullet item for the replacement, or you can continue using them with "from talib import deprecated" for the time being.

• [NEW]: The new moving average types are in talib.MA_Type. It's a class with SMA, EMA, DEMA, etc attribute variables you should now use. Human-readable lookups are also possible by using MA_Type as a dict e.g.:

  MA_Type[MA_Type.SMA] # returns "Simple Moving Average"

• [NEW]: In addition to the existing func interface, we now provide an enhanced abstract interface too. Functions in "import talib" use the original interface, or you can use "from talib import abstract" for the full abstract interface. See the README, tools/example.py and tests/abstract_test.py for more information. The full (commented) source code is mostly located in talib/abstract.pyx. The basic usage is very similar:

  input_arrays = { 'open': np.random.random(100), 'high': np.random.random(100), 'low': np.random.random(100), 'close': np.random.random(100), 'volume': np.random.random(100) } ema_20 = abstract.Function('ema', input_arrays, 20).outputs # function names not case-sensitive slowd, slowk = abstract.Function('STOCH')(input_arrays, 15, 3, 0, 3, 0) upper, middle, lower = abstract.Function('bbands')(input_arrays, timeperiod=20)

• Move the functions into talib.func, to prepare for talib.abstract in a future release.

• Support for MacPorts.
• Fix for FreeBSD.
