|---|---|
| 1 06.05.23 - 0.0.3 - Steve Underwood <steveu@coppice.org> | |
| 2 - T.38 now implemented, though it needs further polishing. | |
| 3 - G.726 and G.722 now implemented. | |
| 4 | |
| 5 04.08.29 - 0.0.2 - Steve Underwood <steveu@coppice.org> | |
| 6 - T.4 no longer uses libtiff for compresion and decompression on the line side | |
| 7 (it is still used to handle the TIFF files). Spandsp no longer depends on | |
| 8 accessing the "internals" of libtiff. New 1D and 2D compression and | |
| 9 decompression code now handles the line side. This should be more robust than | |
| 10 using libtiff, and handles the fudging of bad scan lines rather better. | |
| 11 - T.30 line turn-around timing corrected. | |
| 12 - T.30 DCS header contents corrected. | |
| 13 - T.30 provision for V.17 added, as an option. | |
| 14 - T.30 now has a statistics interface, for applications to find details about | |
| 15 image transfers. | |
| 16 - T.30 processing now correctly closes TIFF files are they have been sent. | |
| 17 - FAX header line insertion is now supported for transmitted FAXes. | |
| 18 - asynchronous serial processing now has a V.14 compatible rate adaption option. | |
| 19 - V.8 modem negotiation module added. | |
| 20 - OKI ADPCM now supports Dialogic compatible operation at 6k samples/second, as | |
| 21 well as 8k samples/second, using its own sample rate converter. | |
| 22 - message queuing added to ease things like T.31 handling | |
| 23 - incomplete skeleton (still rather nasty, to be honest) T.31 processing. | |
| 24 - incomplete skeleton of V.22bis added. There is probably quite a bit to do | |
| 25 to get this complete and robust. It probably requires the T.31 processing | |
| 26 be expanded to something more like V.250, so it doesn't just handle FAX. | |
| 27 - Incomplete V.17 added (there could be an IBM patent related to the TCM part of | |
| 28 V.17, but I think it has expired. Don't distribute binaries of spandsp built | |
| 29 with V.17 enabled until this is resolved - and the modem is completed, of | |
| 30 course :-) ). The current version transmits OK. It receives OK with the | |
| 31 long training sequence, but the symbol and carrier syncing isn't good enough | |
| 32 for robust receiving with the short training sequence. | |
| 33 - A basic BER tester has been added. | |
| 34 - The faster modems now have proper shutdown procedures, whether one is defined in | |
| 35 the spec. or not. | |
| 36 - The modems (except simple FSK) now have APIs to access performance information. | |
| 37 - A common GUI (using FLTK) added for the modem tests. | |
| 38 - A bit more documentation added. | |
| 39 - Some API inconsistencies cleaned up. | |
| 40 - The usual bundle of assorted buglet fixes and polishing. | |
| 41 | |
| 42 04.04.29 - 0.0.1k - Steve Underwood <steveu@coppice.org> | |
| 43 - The first version which gives solid faxing for a large number of people. | |
