To name the most important ones: new caching system, Riak support for several modules and introduction of Certificate Manager. Certificate Manager is a feature that has been requested by many organisations, allowing administrators to manage their certificate more easily. From now, starting ejabberd with an invalid certificate will dump a clear entry in ejabberd log file, explaining what’s wrong. Upcoming ACME support will further refine these improvements we’ve worked on early this year to give our users a great experience with certificate management. The new cache system is also a new component that allows fine tuning of ejabberd performance for either small systems or large scale servers. To use data cache for a supported module, you need to set the module option `use_cache`. You also have the possibility to define a maximum number of cache entries and/or maximum life time of cached data, so you keep control on your memory use. Example: ``` modules: mod_roster: use_cache: true cache_size: 10000 cache_life_time: 3600 # 1 hour ``` The cleanup tasks on all ejabberd API also continue, consider checking against few methods rename. ## Changes ### API - Deprecate `misc:encode_base64/1` and `misc:decode_base64/1` - Rename `is_user_exists` function to `user_exists` - Allow api access on both ipv4 and 6 loopback addresses - Fix invalid argument in get\_messages\_susbset ### Admin - Refactor ejabberdctl - Improve ejabberdctl parameters parsing - Quote all paths to allow spaces in directory names - update-deps-releases.pl: Show operations to perform before asking to apply them - Fix Salt import from prosody SCRAMmed password ### Configuration - Validate module options on start\_module/2 - Validate new options before module reloading - Validate second-level options - Introduce `iqdisc` global option - stream\_management listen option deprecated, use mod\_stream\_mgmt - Check presence of some files during option validation - Speedup configuration options lookup - Validate all certfiles on startup - Only validate certfiles if `public_key:short_name_hash/1` is available - Introduce Certficate Manager ### Commands - Add clear\_cache admin command - Parse correctly presence\_broadcast option in change\_room\_option command - Describe command arguments and results in `mod_muc_admin` - Improve export2sql explanation; remove obsolete and duplicated command - Fix and document `push_roster_all` command - Fix mod\_muc\_admin command set\_room\_affiliation - Fix invalid {args,result}\_examples in mod\_muc\_admin - Fix srg\_user\_add/del for non-Mnesia database backends - Make ext\_mod api return rescode ### Compilation - Erlang 17.5 or higher is required (ejabberd\_c2s needs latest maps fixes from OTP-17, see OTP-12402 and OTP-12623) - Add `--enable-system-deps` configure option - Add `--enable-stun` and `--enable-sip` configure options ### Core - Speedup Mnesia tables initialization - Improve Mnesia tables creation and transformation - Improve `ejabberd_c2s:close()` - ejabberd\_c2s: Don’t close session on stream resume - Speedup loading of translation files - Fix `ejabberd_router:is_my_route/1` - Don’t let a receiver crash if a controller is unavailable - Fix OTP-17.5 support - websocket: Catch exception that may happen when sending data over websocket ### Databases - New `sql_connect_timeout` option - New `sql_query_timeout` option - Get rid of sql\_queries.erl - Use round-robin algorithm when selecting worker from DB pool - Add Riak as BOSH RAM backend - Add Riak as mod\_proxy65 RAM backend - Add Riak as mod\_carboncopy RAM backend - Add Riak as router RAM backend - Add Riak as session manager RAM backend - Fix cleaning of Riak route table - Add pubsub import from prosody/metronome - Fix username in mam export - Fix Salt import from prosody SCRAMmed password - In offline export to SQL, first write all DELETE, later all INSERT ### Cache - Implement cache for mod\_announce - Implement cache for mod\_private - Implement cache for mod\_privacy/mod\_blocking - Implement cache for mod\_last - Implement cache for mod\_vcard and mod\_vcard\_xupdate - Implement cache for roster - Add cache options to the validator - Use cache for authentication backends - Use new cache API in mod\_shared\_roster\_ldap - Use new cache API in ejabberd\_oauth - Use new cache API in mod\_mam - Use new cache API in mod\_caps - Use cache in front of Redis/SQL RAM backends ### Modules - mod\_http\_upload: Add support for HTTP File Upload 0.3.0 - mod\_mam: Added export function - mod\_metrics: Don’t leak with UDP sockets - mod\_metrics: New options ip and port - mod\_muc: Allow a room admin to un/subscribe another JID - mod\_offline: Don’t store messages via a single process - mod\_offline: Make sure only jabber:x:event tag is present in offline event - mod\_register: New option ‘access\_remove’ ACL - mod\_stream\_mgmt: Preserve stanza count on timeout - mod\_vcard\_ldap: Parse `ldap_uids` like in eldap\_utils - mod\_client\_state: Reset state on session resume - mod\_metrics: Fix IP address parsing - mod\_pubsub: Avoid useless calls on simples subscriptions - mod\_block\_strangers: Add allow\_local\_users option ### Elixir - Update elixir to v1.4.4 ### Installer - Upgrade OTP to 19.3 ## Feedback As usual, the release is tagged in the Git source code repository on [Github](https://github.com/processone/ejabberd.git?ref=process-one.net).
