| 2 | Changes with respect to 3-0-3: |
|---|
| 3 | |
|---|
| 4 | - SAGE patches (for building libsingular) integrated |
|---|
| 5 | - flex/bison generated files integrated: these files will only |
|---|
| 6 | be regenerated if removed; |
|---|
| 7 | a normal build will no longer need bison and flex, but configure still |
|---|
| 8 | tests for them. |
|---|
| 9 | - gftables changed to tables based on Conway polynomials |
|---|
| 10 | (see factory/ConwayList.txt) and more tables created |
|---|
| 11 | (for all fields of char p < 255 with < 2^16 elements) |
|---|
| 12 | - multivariate GCD (in char 0, no extension) improved |
|---|
| 13 | by a modular method: selected by On(SW_USE_CHINREM_GCD), on by default |
|---|
| 14 | - modgen has no longer a builtin path: |
|---|
| 15 | change SINGULARROOT in the generated Makefile if you dislike the default |
|---|

|---|
| 28 | - doc/general.doc: description of algorithms updated |
