 Priority:  Normal               |  Milestone:
Component:  ports                |    Version:  2.3.3
 Keywords:  haspatch maintainer  |       Port:  octave-io
---------------------------------+--------------------------------
 octave-io has been updated to version 2.2.8:

 ** Bug fixes:
 * xlsread: properly fall back to dlmread when reading .csv files (don't
 bother with COM (Excel) or UNO (LibreOffice) interfaces)
 * private/__COM_spsh_open__.m: use entire given pathname to convert to
 full path, not just filename proper
 * Same for private/__UNO_spsh_open__.m
 * xlsread.m/xls2oct.m using OCT interface: fix wrong worksheet reference

 This will be (one of) the last io package release(s) before the
 spreadsheet I/O is moved into core Octave, so this version will only
 install in Octave < 4.2.x (override using the -nodeps option with pkg.m)

 Also replaced nomaintainer with openmaintainer (an oversight in the
 previous release).
