I was using the term 'issue' pejoratively there to match the phrase 'crash mag'. They are still issued as individual publications for each accident, although perhaps a little thinner now than in years gone by.
In the period where the publications were thin on the ground, there was a bit of communication down the flight safety chain with things like 'Feedback' - essentially brief summaries of incident reports. But it was all a mess, which is why (rightly) the decision to rebuild the IFS was eventually taken.
