leshan-2.0.0-M1

❗☠️❗ Affected by security issue❗☠️❗

Build artifacts are available on maven central.

First development release on track for LWM2M 1.1, see LWM2M 1.1 supported features.
⚠️ As a milestone release keep in mind API could be broken.
(As this is the first milestone, I can even guarantee that API will be broken 😅)

If you are interested in LWM2M 1.1 support in Leshan, we strongly advice to :

• use/test this milestone release,
• report us any bug or feebacks,
• share what part of LWM2M 1.1 missing you more,
• contribute code.

This is the best way to get a final 2.0.0 release which fit your needs.

You are more and more to contribute to Leshan, thx to all of you ! 🙏

Noteworthy

• add support to LWM2M 1.1 object model. #870
• embed last models. #870
• refactor model validation to support both model format, LWM2M 1.0 and LWM2M 1.1. #870
• add resource instance support for Read/Write request using text/tlv/json content format. #877
• add unsigned integer support. #879 #880
• add LowerLayerConfig class to tweak lower layer request parameter. #876
• Integration of Californium 2.4.1.(2.4.0 change log)
• some bug fixes.

Thx to @zakharenkodmytro for "resource instance operation" contribution 🙏 !

Noteworthy

Cleaning Bootstrap Server API.

Notable API/behavior break

2. Redis store implementation are moved in a leshan-redis-server project (#679)
3. Old TLV/JSON code is not supported by default anymore (#720)
4. No more magic conversion by default at encoding time (#710)
5. With new object versioning, only model reported in registration are used, you can keep the old behavior like this.
6. Lot of bootstrap server API break, mainly renaming (#713)

Known Issue :

#757: Memory leak in DTLS Connection Store.
