Hi Emilio,

thanks for bringing up this issue on the LTS list.

MySQL 5.5 should be EOL this month if nothing has changed, although I don't see
an announcement on [1] yet. Maybe it will be published next month when the next
CPU (critical patch update) is released. Norvald, do you know if 5.5 is
effectively EOL already? Or will it receive another update next month?
[Norvald replied, saying that 5.5.62 in October was the last 5.5
Right. 5.5.62 was the final 5.5 release.
Also note that mariadb 10.0 is EOL in three months[2].
I think this rules out mariadb 10.0 as a sensible upgrade path here.
(Also, switching from mysql to mariadb in an LTS security upload???)

I don't think it makes much sense to upload mysql-5.6, since stretch has no
mysql at all. Since users will have to migrate to MariaDB anyway (or to
externally provided MySQL packages if they so choose), they can do so now.
following that logic they could also upgrade to Stretch now... :)

For mariadb 10.0, we may be able to backport important security fixes, or we
could backport 10.1 which will be supported upstream until October 2020.

I would lean towards one of those last two options.
I think I'm rather *leaning* towards mysql-5.6 or declaring mysql-5.5
unsupported/EOL in jessie, but that's really leaning, nothing more.
(And then I believe mysql-5.6 in jessie isnt simple/feasable neither, so... :/

Other comments/suggestions?

Upgrading to 5.6 would be less risky than MariaDB 10.1, but it's a similar sort of risk. Building: Since both 5.5 and 5.6 have libmysqlclient18 I don't expect many issues, but 5.6 and 5.5 "leaked" symbols, so even internal symbols were published. Third-party packages using internal symbols in 5.5 may fail to build with 5.6.

User experience: 5.5 and 5.6 will be very similar for most users (particularly, init scripts in third-party packages shouldn't be impacted), but anyone still using jessie and 5.5 may have pretty strict stability requirements.

There's a summary of changes here:
