I'll save this repos in case anyone cares. Output of

    hg log -l20 -GT '{rev} {desc|firstline}'

@  716 Speed up database loading.
|
| o  715 Remove debian/get-orig-source.
| |
| o  714 Override default sdist with CustomSdist class to build orig tarball.
| |
| o    713 Branch merge with debian branch. Henceforth the debian/ directory
will be in the default branch.
| |\
+---o  712 * write_data_file: Remove.
| |
o |  711 Add 'id' as an argument to the Gene class, corresponding to the gene
table.
| |
o |  710 Remove 'startpos' and 'endpos' from write_data_file_partial. Rename to
write_data_file. Function now processes entire gene.
| |
o |  709 Throw error if stated model length is smaller than actual (incomplete)
model length.
| |
| o  708 Branch merge with default.
|/|
o |  707 Check that the data frames True, Sim, and Data are not empty in
'get_stat'.
| |
o |  706 Bugfix in load_sequence_dataset. Forgot to check for simulated = 'f'
in conditional.
| |
o |  705 Typo fix in make_sequencestatgroup_table docstring.
| |
| o  704 Branch merge with default.
|/|
o |  703 Add score column to crossval table.
| |
o |  702 simann: Check that method string is correct.
| |
o |  701 Add 'search' boolean column to Crossvalgroup table. Change constraint
| |
o |  700 Bugfix in crossval function.
| |
o |  699 Correctly specify location of local 'default_conf.yaml'.
| |
o |  698 Add comments to linsplit::method. Exit from simann is model has length
<= 1.
| |
o |  697 On second thoughts, per Jarod42's suggestion in
http://stackoverflow.com/a/24530120/350713,
