III. mLinux 5.3.0bOverview
- 1.mLinux 5.3.0bdoesnot include support for Node.js
- Current mLinux versions (mLinux 5.2.7 and earlier) support Node.js version 0.10.48-r1.7.0
- The requirement to upgrade to OpenSSL 1.1 in mLinux 5.3.0bmeans that the Conduit family of programmable gateways can no longer support Node.js applications due to security protocol vulnerabilities that exists within Node.js
- mLinux 5.3.0bdoes not include support for Ruby
- Current mLinux versions (mLinux 5.2.7 and earlier) support Ruby version 2.2.5-r0.0
- Other software packageshave been removed or revised
- Contact support@multitech.comfor details
- Upgrade to Yocto 2.6.4 (codename: Thud)
- Current mLinux versions (mLinux 5.2.7and earlier)are built using Yocto 2.2.4 (codename: Morty).
- Yocto 2.6.4 introduces a large numberof new software versions
- It is recommended that user applications be re-compiledand re-linked using either BitBake or the toolchain to be compatible with newer software libraries
- Upgrade to OpenSSL 1.1.1b
- Current mLinux versions (mLinux 5.2.7) supports OpenSSL 1.0.2k
- mLinux 5.3.0bsupports OpenSSL 1.1.1b
- Support for LXFP utility replaced with UXFP utility
- Utilities used to upgrade Telit radio firmware
- UXFP utility: Available on mLinux 5.3.0b and laterhttp://www.multitech.net/developer/software/mlinux/using-mlinux/using-uxfp-to-upgrade-telit-firmware/
- LXFP utility: Available on mLinux 5.2.7 and earlierhttp://www.multitech.net/developer/software/mlinux/using-mlinux/using-lxfp-to-upgrade-telit-firmware/
- Support added for AS923 LoRa Frequency Plans
- AS923-1, AS923-2, AS923-3
- Support added for new software packages
- Contact support@multitech.comfor details
- Many current software packages have been revisedand support for new software packages hasbeen added.Contactsupport@multitech.comfor details
- No upgrade package install
- mLinux 5.3.0bincludes a large number of version updates
- Due to these changes, a full image install is required to move from prior mLinux versions (i.e.mLinux5.2.7) to mLinux5.3.0b
- Failure to perform a full image install in upgrading to mLinux 5.3.0bwill result in an upgrade failure
- Group Sudo changes
- Path for commissioned users and all users in group Sudo now includes /sbin and /usr/sbin.
- This existed in versions of mLinux prior to 5.2.7
- Cellular Modem APN Behavior Changes
- When changing the cellular modem APN, there was a chance that the device mightnot register successfully (i.e. bad reception)
- When this occurs, the cellular modem is left with a mode setting of COPS=2 or CFUN=0. This prevents all future ppp connections
- This has been corrected. mLinux 5.3.0bchecks for CFUN=1 and COPS=0 before attempting to register the cellular modem
- mLinux 5.3.0balso sets CFUN=1 and COPS=0 before attempting to register the cellular modem
mLinux 5.3.0b is amajorsoftware release built upon mLinux 5.2.7. The new features, feature enhancements, bug fixes, and known behaviors announced in mLinux 5.2.7are also available in mLinux 5.3.0b. |
