@jmikola After a review of docs, this was only unnecessary mention of an older version. Let me know what you think or if there were other particular spots you had in mind, thanks!

After a review of docs, this was only unnecessary mention of an older version

I found four references to older server versions in the docs:

• The introductory paragraph in decimal128.txt starts with "MongoDB 3.4 introduced support for..." This can be rewritten to just say "The Decimal128 BSON type is a 128-bit decimal-based..."
• The description of the flags option in MongoDBDatabase-createCollection.txt includes "MongoDB 3.0 and later". I think that entire paragraph can be removed, as the manual links no longer contain any content on the subject. I also opened PHPLIB-1545 and PHPLIB-1546 to deprecate and remove the option in PHPLIB 1.21 an 2.0, respectively. It's a relic of the MMAPv1 storage engine.
• Also in MongoDBDatabase-createCollection.txt, you can remove "This option has been deprecated since MongoDB 3.2" from the description of the autoIndexId option.
• collation.txt starts with "MongoDB 3.4 introduced", which can be rewritten as "Collations provide a set of rules..." (preserving the manual link if it's still valid). This is comparable to what I suggested above for Decimal128.

@jmikola Is it safe to remove autoIndexId from MongoDBDatabase-createCollection.txt? I don't see autoIndexId on the manual page, and it seems it can only be set to to true now anyways.
Thanks for flagging the above tickets; we can address these to remove the flag option once the engineering tickets are out of code review.

Is it safe to remove autoIndexId from MongoDBDatabase-createCollection.txt? I don't see autoIndexId on the manual page, and it seems it can only be set to to true now anyways.

Note that autoIndexId can be false when creating a collection in the non-replicated local database. PHPLIB-1159 removes the option in PHPLIB 2.0 and there's already a corresponding docs ticket (DOCSP-44238), so I don't think it needs to be touched in this PR.

As for the server manual, it should be documented as it's is still technically party of the create command API. I opened DOCSP-43428 some time ago to track that, as it looks like it was inadvertently removed from the manual in recent years.

One question about adding "the". Regardless of whether that is changed, LGTM and no need to review a second time.
