Changelog
This page lists every content update we make in response to a regulatory change: what changed, when the change was announced, when our affected questions were pulled, and when their replacements went live. Dates included, every time.
We publish this because “always up to date” is an easy thing to say and a hard thing to prove. This is the proof — or, if we ever slip, the receipt for that too. A swept-and-confirmed entry counts too: it's proof the monitoring is being read, not just running.
Seven CPF and HDB page changes reviewed — no practice content affected
Monitoring detected changed page content on CPF's lease-age-95 guidance and six HDB pages covering Community Care Apartments, the HFE letter, home maintenance, renovations and upgrading. Each page was refetched and checked against the knowledge units grounded on it. No proposition used by a live question had changed, so no content needed to be withdrawn or rewritten.
HDB shops-and-offices and Request for Value guidance — affected practice content held for review
Source triage found six shops-and-offices knowledge units and one Request for Value knowledge unit that may be affected. Their linked practice content is being kept out of circulation while replacement knowledge units and questions complete human review. This entry will be updated when that review is resolved.
Eight other HDB page changes reviewed — no practice content affected
Apparent changes on HDB's business-partner, commercial-property, Executive Condominium, financial-planning, rental, renting, selling and news pages were refetched and compared with the knowledge base. The review found no changed exam proposition on those pages, so their questions remained available.
Incomplete HDB and CPF fetches caught — temporarily held questions restored
Two source fetches returned sharply incomplete copies of HDB buying guidance and CPF loan guidance. The monitoring system initially treated those incomplete copies as substantive changes and temporarily withheld 165 questions. We verified that the official rules had not changed, restored every affected question the same day, retired the unusable generated drafts, and added a pre-withdrawal guard that rejects a fetched source if it collapses below half of its registered size.
URA change-of-use and HDB Community Care pages reviewed — no practice content affected
Monitoring detected apparent updates across three URA change-of-use and circular pages and HDB's Community Care Apartments page. The refreshed pages were checked against their grounded knowledge units. No new change to an exam proposition was found, so no practice content needed updating.
CPF Home Protection Scheme rechecked — no rule change; three questions restored
A stale detector signal caused one supported knowledge unit and three linked questions to be withheld for rechecking. The current official CPF material still supported the rule verbatim. We restored all four records, cancelled the unnecessary replacement batch before it inserted anything, and added a byte-identity guard so an unchanged current source cannot trigger the same containment path again.
CPF Home Ownership guidanceSeven HDB and CPF page changes reviewed — no additional practice updates required
Between 20 and 23 July, monitoring raised apparent changes on HDB selling, housing-loan and renting pages and a CPF housing-scheme page. Each was refetched and compared with the grounded content. Apart from the separately recorded CPF and Community Care remediation, these checks found no additional changed exam proposition.
CPF housing and HDB Community Care guidance refreshed — replacement practice set live
Monitoring identified changes in the CPF housing-usage material and HDB's Community Care Apartments guidance. We withheld 67 affected questions before candidates could continue receiving them, captured immutable current source copies, rebuilt and independently verified the affected knowledge, and completed human review of the replacements. Ninety replacement questions — 65 standalone and 25 case-study questions — went live after review; the original affected questions remain out of circulation.
URA conservation and renting-property guidance restructured — reviewed, no exam content affected
URA reorganised its website and moved its conservation guidelines and private-residential renting rules to new pages, rewriting some of the surrounding text. We detected the change, re-read every affected page, and checked it against the 66 knowledge units that rely on these sources. The changes were editorial — reorganisation and rewording — with no change to any underlying rule: the conservation restoration parameters and the private-residential occupancy caps (including the temporary relaxation running to 31 December 2028) all still read exactly as our questions assume. No questions or knowledge units needed updating.
URA Conservation Guidelines (current page)Housing and Development (Common Property and Open Spaces) (Amendment) Rules 2026 — reviewed, no exam content affected
Checked HDB, URA, CPF, CEA, IRAS, and 39 tracked Acts via Singapore Statutes Online for changes since the knowledge base was built. One new piece of subsidiary legislation went live 15 July 2026: the Housing and Development (Common Property and Open Spaces) (Amendment) Rules 2026. It covers vehicle clamping and towing fees on HDB estates, which is outside the RES syllabus, so no questions or knowledge units needed updating.
