[celix] branch develop updated (f9f3207 -> 043b77e)
This is an automated email from the ASF dual-hosted git repository.
pnoltes pushed a change to branch develop
in repository https://gitbox.apache.org/repos/asf/celix.git.
from f9f3207 Updated logging statement in PSA ZMQ
new 68f7918 Fixes an issue in http_admin with using the (internal) save_ptr of strtok_r and update etcdlib to use a apaque instance pointer.
new 043b77e For now disables the deprecated attribute on the glocal etcdlib calls.
The 2 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails. The revisions
listed as "add" were already present in the repository and have only
