<br></div><div>#---------------------------------- 0.25.0 -----------------------------------</div><div>[changed] version numbers to account for bugfixes vs. feature updates.</div><div>[added] columns can now be defined to allow for prefix and/or suffix queries.</div>
<div> Enabling prefix queries also enables arbitrary pattern matching over your</div><div> data.</div><div>[fixed] in some cases, rom would allow the definition of multiple primary</div><div> keys, of which only one would ever be used (inconsistently). This will now</div>
<div> result in an error.</div><div>[changed] defaulted to assume Lua is available on Redis, which has been</div><div> released for over 15 months at this point. You can disable support via</div><div> a call to rom._disable_lua_writes().</div>
<div>[added] the ability to cache and get the key that holds the result of a query,</div><div> which can be used for pagination, etc. See: Query.cached_result()</div><div>[warning] using rom versions of 0.23 with 0.25.0 when prefix and suffix</div>
<div> indexes are enabled can result in improper results from prefix, suffix,</div><div> and/or pattern queries, and can result in orphan data living in prefix or</div><div> suffix indexes. Upgrade all of your clients!</div>
<div>[changed] temporary keys for queries are now prefixed with the name of the</div><div> model over which queries are being executed on. This should effect</div><div> basically zero people, but can allow for query cleanup in the off chance</div>
<div> of a failure during execution.</div><div>#----------------------------- 0.23 (unreleased) -----------------------------</div><div>[changed] reduced number of round trips for single-filter queries by 1, thanks</div>

<div> Model.get_by(attr=value) or Model.get_by(attr=(min, max)) by roughly a</div><div> factor of 60x or better in some cases. Thank you to</div><div> <a href="https://github.com/MickeyKim" target="_blank">https://github.com/MickeyKim</a> for the report on poor performance.</div>
