||||||
|
* Fix an issue related to data being sent to the libsigrok session which
|
||||||
|
was not a multiple of the unit/sample size (bugs, #289, #290).
|
||||||
|

|
||||||
|
* libsigrok session files:
|
||||||

|
||||||
|
file format 'version' field is bumped to 2. Older libsigrok versions will
|
||||||
|
not be able to handle version 2 files, but new libsigrok versions can
|
||||||
|
handle both version 1 and version 2 files. New libsigrok versions will
|
||||||
|
always write/output version 2 files.

||||||
|

|
||||||
|

|
||||||
|
* Major API changes (overview):
|
||||||
|
- Change various function/macro names related to the probe->channel rename.
|
||||||
|
- Change various functions due to the new channel group feature.
|
||||||
|
- All enums in the public API now have names (e.g. 'enum sr_mqflag').
|
||||||
|
- The lib no longer defineѕ names with _t suffix (POSIX reserved).
|
||||||
|
- New API calls:
|
||||||
|
- sr_session_dev_list()
|
||||||
|
- sr_session_save_init()
|
||||||
|
- sr_session_append()
|
||||||
|
- sr_config_commit()
|
||||||
|
- sr_output_new()
|
||||||
|
- sr_output_send()
|
||||||
|
- sr_output_free()
|
||||||
|
- Obsoleted and removed API calls:
|
||||||
|
- sr_filter_channels()
|
||||||
|
- 'struct sr_session' is now opaque (contents shouldn't be used directly).
|
||||||
|
- Please see the Doxygen API documentation for further details.
|
||||||
|
* Build system:
|
||||||
|
- Switch to a non-recursive automake setup (fewer files, faster builds).
|
||||||
|
- configure: Clearly mark required and optional libs.
