v0.4.1 ssmtp&msmtp

Having both ssmtp & msmtp so we can support sending mail from older devices as well.
Many will never get updates, but could eventually get a security update.
At least for now, we keep both...

v0.4.0 msmtp

Migrates from ssmtp (deprecated) to msmtp

v0.3.6 - Fix for enigma2 systems

Fix package listings by removing extra line printed in enigma2 systems.

v0.3.5

• Change which calls to command -v

v0.3.4

v0.3.4 :

• Load info from /etc/openwrt_release when available
• Add more router info on email report (from openwrt_release)
• Detect if the system is a DISTRIB_RELEASE='SNAPSHOT' and show warning about upgrading those
• New/prettier HTML email (new font type, sizes and info table)
• Code cleanup from v0.3.0 implementations

v0.3.2

• Ignore opkg errors when listing upgrades.

Used to abort execution if opkg returned any errors when listing packages,
but that is not really needed and may break execution.

Disabled.

v0.3.1

• New table print was ignoring first package when printing to screen.
• Actual upgrade process was fine, just printing was affected.

v0.3.0

v0.3.0 :

• Sort package list by package names
• Ignore opkg warnings
  • opkg list-upgradable may print something like "Multiple packages (libpthread and libpthread) providing same name marked HOLD or PREFER. Using latest." within the list. This used to cause an error because it would be parsed as a package name.
  • It was kind of rare though. I THINK it only happens on TRUNK/BETA versions that are very old.
• Use awk + printf to print an ASCII table of the updates (prettier)

---

Example of the new/prettier package list:

# ./opkg-upgrade.sh -n

Simple OPKG Updater v0.3.0

Done | Ignoring package lists update
Done | Getting upgradable packages list
