Joomla Miscellaneous API changes: Joomla 3 → 4, 5 and 6

18 issues in this guide

Everything that does not own a subsystem guide still needs a namespaced home. This miscellaneous guide groups 18 catalog entries: JBuffer, JCaptcha, JCrypt, JDate, JHelp, JKeychain, JLog, JLogEntry, JLogLoggerFormattedtext, JNode, and 8 more. The replacement pattern is almost always a use statement for the Joomla\CMS\… (or Joomla\Registry\Registry) class listed in each entry, deletion of wrapper indirection, and third-party OAuth libraries where the old social package was removed. Profiler timing becomes microtime(true) / memory_get_usage() where helpers vanished. Hop mix: 5 at Joomla 3 → 4; 13 at Joomla 5 → 6. None of these entries invent new product statistics — they only record what the catalog already documents as removed, aliased, or replaced. Scan this list when a Class not found does not match Factory, Form, Table, or HTMLHelper, then jump to the matching anchor for the mechanical fix. Catalog replacements in this guide include JBuffer → Joomla\CMS\Utility\BufferStreamHandler; JCaptcha → Joomla\CMS\Captcha\Captcha; JCrypt → Joomla\CMS\Crypt\Crypt; JDate → Joomla\CMS\Date\Date. Open each h2 anchor for the full before/after, fix list, and error strings shipped in the reference data.
