Release 2.8.1

Changes

• continuous integration with Travis CI (thank to Mihai)
• initial test (thank to Mihai)
• avoid unnecessary duplication of channels when filtering measurements with channel compositions

Fixes

• fixes for channel composition in mdf version 4 (thanks to Julien Grawe)
• multiple documentation fixes (thanks to Mihai)
• multiple fixes for mdf version 2 files

Version 2.8.0

Changes

• support MDF version 2.14
• add new resample method to MDF
• try to avoid MemoryError for append on 32 bit Python
• add get_channel_comment and get_channel_unit methods
• add save overwrite as configurable option
• added possibility to return pandas DataFrame to select method
• pandas is now a required dependency

Fixes

• use data block size equal to multiple of record size when splitting data blocks in mdf version 4 save
• fix default values for memory argument in MDF methods
• fix incompatible plot title in Signal
• handle backslash in channel names
• fix typo in usage example
• fix iter_to_pandas error
• fix and improve info methods

Version 2.7.1

Fixes

• fix missing attribute error in Signal class when plotting surface (map) signals

Version 2.7.0

API change

• load_measure_data argument was replaced by memory argument:
  • load_measured_data=True ⇔ memory="full"
  • load_measured_data=False ⇔ memory="low"
  • memory="minimum" is new and will use the least possible amount of RAM (see http://asammdf.readthedocs.io/en/latest/benchmarks.html for benchmark results)

Fixes

• fix errors in save method
• fix errors in merge method
• fix error in cut method for channel groups with no cycles
• fix mdf 4 TextBlock 8byte alignment
• fix wrong link to sample reduction block in ChannelGroup for mdf 4
• fix append and get in case of mdf 4 TTAB conversions
• fix error in case of mdf 4 TTRANS conversion

Version 2.6.7

Fixes

• fix error in MDF3 save method
• fix select method to return the signals in the same order as the channels given
• fix get method when channel group cycles number is 0

Version 2.6.6

Changes

• added select generator method to MDF
• added config pacakge level function to handle all asammdf configurations
• use data list and split data block when saving (configurable)

Fixes

• fix mdf v3 POLY Conversion
• fix mdf v4 DataList for Python 2
• PEP8 improvements

Version 2.6.5

Changes

• big performance boost for convert, cut, export, filter, merge and iter_to_pandas when load_measured_data=True

Fixes

• fix incomplete implementation of mdf version 4 DLBLOCK

Version 2.6.4

Changes

• allow compacting of signed integers when appending
  • use the package function enable_integer_compacting
• avoid unnecessary computation for polynomial conversions
• add MLSD channel support
• improve plotting of maps and update Signal usage example
• moved __version__ to version.py

Fixes

• fix errors in HDF5 export
• fix error in get for singed integers of nonstandard size
• fix mask error for nonstandard integers
• fix error in MDF4 get method when channel type was virtual master
