0.29.0
Interface changes / additions

containing the query’s or table’s rows. (#4354)Iterate over a
QueryJob

andDataset.reference
properties to get theTableReference
orDatasetReference
corresponding to thatTable
orDataset

0.28.0
0.28.0 significantly changes the interface for this package. For examples of the differences between 0.28.0 and previous versions, see Migrating to the BigQuery Python client library 0.28. These changes can be summarized as follows:
Query and view operations default to the standard SQL dialect. (#4192)
Client functions related to jobs, like running queries, immediately start the job.
Functions to create, get, update, delete datasets and tables moved to the client class.
Fixes
Populate timeout parameter correctly for queries (#4209)
Automatically retry idempotent RPCs (#4148, #4178)
Parse timestamps in query parameters using canonical format (#3945)
Parse array parameters that contain a struct type. (#4040)
Support Sub Second Datetimes in row data (#3901, #3915, #3926), h/t @page1
Interface changes / additions
Support external table configuration (#4182) in query jobs (#4191) and tables (#4193).
New
Row
class allows for access by integer index like a tuple, string index like a dictionary, or attribute access like an object. (#4149)Add option for job ID generation with user-supplied prefix (#4198)

transport attached to a Client for for resumable media (i.e. downloads and uploads) (#3705) (this relates to thehttplib2
torequests
switch)
Interface changes / additions
Adding
autodetect
property onLoadTableFromStorageJob
to enable schema autodetection. (#3648)Implementing the Python Futures interface for Jobs. Call
job.result()
to wait for jobs to complete instead of polling manually on the job status. (#3626)Adding
is_nullable
property onSchemaField
. Can be used to check if a column is nullable. (#3620)job_name
argument added toTable.upload_from_file
for setting the job ID. (#3605)Adding
