[CHANGE]: talib.stream is now the real streaming API of TA-Lib C 0.8.1: stream.SMA(close) returns a handle, not a value. handle.value is the value at the last history bar, handle.update(bar) costs O(1) and returns that bar's value, handle.peek(bar) evaluates a forming bar without committing it, and handle.copy() forks it. stream.SMA.open_and_fill() returns the handle and the Function API's series in one pass. A multi-output function answers with the same tuple the Function API returns. The old last-value functions -- talib.stream.SMA, talib.stream_SMA, and their _ta_lib.pyi stubs -- are gone; talib/stream.pyi types the handles instead.

Migrating is stream.X(...) -> stream.X(...).value, and the compiler cannot find the sites for you: if stream.CDLDOJI(o, h, l, c): used to test the pattern and now tests a handle, which is always true.

[NEW]: talib.InsufficientHistory, raised when a stream is opened with too little history. It is the library's one recoverable error, so it is catchable on its own rather than as a bare Exception.

[FIX]: help(talib.SUPERTREND) and the abstract stub named the outputs real and integer; they are supertrend and trend, the names abstract.Function('SUPERTREND').output_names already reported.

[FIX]: An empty array given to a function whose lookback is zero, such as talib.ACOS or talib.MA(x, timeperiod=1), made TA-Lib read and write one element outside the buffers, which could crash the interpreter later or corrupt memory silently. An empty input now returns empty outputs without calling TA-Lib, whatever the function and its parameters. The bug dates from 0.4.27.

[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.
